What you need to know about deep groove ball bearings

Deep groove ball bearings are a type of rolling bearing that is widely used in various industries and applications. They consist of an inner ring, an outer ring, a set of cages, and a set of balls.

The ball and cage roll between the inner and outer rings. The balls are guided by the cage and retain the grease in the bearing. The deep groove raceway of deep groove ball bearings is small and deep. They are the most common bearing type, accounting for more than 70% of all bearing applications.

What is a deep groove ball bearing?

Deep groove ball bearings are a type of bearing used in a variety of applications. These bearings have a deep groove in the outer ring, making them suitable for high-load and high-speed applications. Deep groove ball bearings are the most commonly used bearing type and are available in a variety of sizes and designs.

Deep groove ball bearings are available in a variety of materials including steel, stainless steel, and ceramic. These bearings have deep groove raceways on the inner and outer rings of the bearing. These bearings are typically used to support radial loads, but can also be used to support axial loads in both directions. The balls in the bearing are also specially designed to withstand high loads.

Types and uses of deep groove ball bearings

Deep groove ball bearings are versatile and can be used in a variety of applications from automotive to aerospace. There are many different types of deep groove ball bearings, each with its own unique characteristics and advantages.

Over the years, manufacturers have improved the design of deep groove bearings, resulting in several different types. These types are usually more suitable for some specific applications.

Single-row deep groove ball bearings

Single-row deep groove ball bearings are typical deep groove ball bearings with a single raceway. They are generally strong and made of durable materials, ensuring that these bearings have a longer life.

Single-row deep groove ball bearings are also subdivided into other types, with bore diameters ranging from 3mm to 400mm, making them suitable for almost any application. Some manufacturers will also offer thin, narrow, wide, or miniature bearings depending on the customer’s needs.

Because deep groove ball bearings are required to withstand extreme conditions, manufacturers also offer ceramic-coated bearings to handle electrical pitting and high-temperature installations that can withstand up to 660 degrees Fahrenheit.

One of the latest developments in single-row deep groove ball bearings is the sensor bearing, which measures the condition of ball-bearing components. Simple to use, these units assist with speed sensing, angular position measurement, and steering, making them useful for electric motors, tractors, conveyors, and road rollers.

Sealed deep groove ball bearings

Sealed deep groove ball bearings are similar to single-row deep groove ball bearings except that they have an iron or rubber protective cover installed on one or both sides of the bearing. These seals are pre-greased to extend bearing life.

Many manufacturers use sealed ball bearings in contaminated environments that could otherwise affect bearing performance. The protective cover helps the bearing retain grease while also preventing any contaminants from entering the bearing itself.

Larger deep groove ball bearings can even use machined brass cages for high-speed applications, where the cage prevents unnecessary wear.

Flanged deep groove ball bearings

Some deep groove ball bearings have a flanged outer ring that works like a snap ring on a standard ball bearing. Flanges increase the operating efficiency of the bearing and are also easier to machine due to the simplicity of the housing bore.

Flanged deep groove ball bearings are ideal for axial loads, for example on pipe ends or belt guides. Some variants even have rotating housings to allow for slight misalignment and better axial loading.

Double-row deep groove ball bearings

The double-row design significantly increases load-carrying capacity while still maintaining the low friction characteristics of the bearing. Double-row bearings are generally slightly wider than single-row bearings and are almost as versatile and practical.

The main disadvantage of double-row deep groove ball bearings is that they have no seals or guards, although some may have cages. These cages facilitate installation and assembly but are susceptible to mechanical stress during operation. Selecting the correct type of cage for a specific application is critical, especially when certain cage materials are sensitive to specific lubricants.

How do deep groove ball bearings work?

Deep groove ball bearings are commonly used in rotating applications such as motors, wheels, and pumps. But how do they work?

Deep groove ball bearings have a series of balls in the middle of the inner and outer rings, the balls can rotate freely in the rings, and they act as the contact point between the two rings. When the shaft turns, the inner ring turns with it.

This also causes the ball bearings to rotate. However, since ball bearings can rotate freely, they can also roll in grooves around the circumference of the inner ring. This rolling action helps reduce friction between the shaft and the bearing.

How deep groove ball bearings work

Deep groove ball bearings mainly bear radial load, and can also bear radial load and axial load at the same time. When only radial load is applied, the contact angle is zero. When the deep groove ball bearing has enough radial clearance, it has the performance of an angular contact bearing and can bear a large axial load. Deep groove ball bearings have a small friction coefficient and high limit speed.

Features of deep groove ball bearings

The deep groove ball bearing has a simple structure and is easy to use. Compared with other types of bearings with the same specifications as deep groove ball bearings, this type of bearing has a small friction coefficient and a high limit speed. But it is not shock resistant and not suitable for heavy loads.

After the deep groove ball bearing is mounted on the shaft, the axial displacement of the rod or housing can be limited within the axial clearance of the bearing, enabling it to be positioned axially in both directions. In addition, these bearings also have specific self-aligning capabilities. When tilted 2′ to 10′ relative to the bearing housing hole, it still works normally but has a special effect on bearing life.

Structure of deep groove ball bearing

The manufacturing accuracy of deep groove ball bearings is easier to achieve than other types, so it is convenient for mass production, has low manufacturing costs, and is ubiquitous.

In addition to the main models, deep groove ball bearings also have various modified structures, such as deep groove ball bearings with dust caps, deep groove ball bearings with rubber seals, deep groove ball bearings with retaining grooves, and ball grooves. Mouth-deep groove ball bearings, etc. Large carrying capacity, double row deep groove ball bearings.

The advantages of using deep groove ball bearings

Deep groove ball bearings are characterized by versatility and durability. When selecting bearings for a specific application, it is important to consider the advantages and disadvantages of each bearing.

Deep groove ball bearings have several advantages over other types of bearings including:

• Versatility

Because they can withstand radial and axial loads, they have wider applications in many industries. They are available with and without a dust cover and can be used in any environment.

• Cut costs

Deep groove ball bearings generate less friction torque. This lowers the operating temperature, which extends the life of the bearings, and also reduces the energy costs of running the equipment.

• Low friction

Deep groove ball bearings generate less friction than standard bearings, which can save costs in a number of ways. First, it reduces the operating temperature of the bearing, thereby extending the service life of the bearing. Operating machines with bearings also becomes cheaper due to increased efficiency and reduced maintenance requirements. Low friction also reduces noise and vibration, making these bearings ideal for high-rotation environments, and they use less lubrication than conventional bearings.

How to choose a suitable deep groove ball bearing

In many applications, deep groove ball bearings are ideal. They are widely used in machinery and equipment because they are inexpensive, durable, and require little maintenance.

However, there are different types of deep groove ball bearings to choose from, each with its own unique features and benefits. So how do you choose the right bearing for your application?

The following points need to be considered when selecting a deep groove ball bearing:

• Size

The space allowed by the bearing is usually quite limited. In many cases, the shaft diameter or bearing bore diameter is determined by design requirements. Therefore, the type and size of the bearing must conform to the established specifications.

• Accuracy requirements

The second biggest consideration when choosing a bearing is accuracy. Certain applications, such as bearings for CNC machine tools, require high precision. In other applications, such as scooter wheels, accuracy will not be a major issue.

• Bearing load

The amount of load the bearing must carry will have a major impact on which type of bearing should be used for a particular application. Additionally, the various loads managed by the bearing can significantly affect sustained performance and must be carefully evaluated during the selection process.

Some bearings must withstand radial loads acting perpendicular to the axis of rotation. Some bearings must withstand axial loads acting parallel to the axis of rotation. If the loads on the bearings deviate from these shafts, moment loads are created.

The nature, magnitude, and direction of applied loads can be highly variable. In general, the basic load ratings shown in bearing dimension tables indicate load-carrying capacity. However, the load type should also be considered when deciding on the correct bearing type.

• Running speed

Each specific bearing has specified speed limits, all determined through empirical testing in a variety of routine applications. Permissible speeds may vary depending on bearing size, type, load level, lubrication, and temperature.

A key factor in a bearing’s high-speed performance is the type and amount of lubrication used. In general, deep groove balls and roller bearings are best suited for high-speed applications.

• Durability

There are many factors to consider when it comes to durability, including stiffness and temperature tolerance. Bearing contact surfaces can deform under load, and deformation can be a serious problem in some applications. Due to the temperature difference between the region of use and the environment of use, the operating temperature range that the bearing can withstand should also be a major selection issue.

• Maintain

Some bearing applications require periodic disassembly and reassembly for inspection and maintenance. In these applications, bearings with separable rings are most suitable.

How to prolong the service life of the bearing, thorough lubrication is also very important. Too much lubrication, too little lubrication, contamination, and mixed lubricants can all have an impact on bearing performance.

How to keep your deep groove ball bearings in good condition

Deep groove ball bearings are essential components in many machines and equipment. They are used to support radial and axial loads and reduce friction in rotating systems. Because of their importance, it is crucial to keep deep groove ball bearings in good condition. Here are some tips on how to do this:

• Handle with care

Bearings are complex and precise and therefore require proper handling and storage. If not, they risk being damaged. It is recommended to store the bearings horizontally in their complete packaging in a clean and dry environment. Avoid exposing the bearing to any contamination as much as possible, as a small piece of dirt in the raceway can cause premature bearing failure.

Under no circumstances should you hammer, tap, or apply direct force to the bearing. This can damage or dislocate the rolling elements inside, rendering them unusable. If the bearing is dropped or mishandled, it should not be installed as any small cracks or scratches will result in reduced performance.

• Check housing and shaft

Before installing any bearing, it is important to inspect the housing and shaft for signs of damage to ensure its physical condition is in operating condition. Wipe the surface clean with a soft cloth, making sure to remove any marks or burrs.

• Install correctly

Different types of bearings require different mounting methods, if you are using a bearing with a cylindrical bore, it is usually mounted using a press fit method, i.e. by pressing the bearing against the shaft, or a shrink fit method, in which the Heat is applied to enlarge the diameter of the bearing. If pressure is applied to the ring without a press fit, the raceways will be damaged and the bearing will not operate as intended.

• Prevent direct heating or overheating

The maximum allowable temperature varies depending on the heat treatment of the bearing. If the temperature exceeds this temperature limit, it may cause permanent deformation or soften the bearing steel. When this happens, the load-carrying capacity is reduced and failures can occur.

• Use the right tools

When you install bearings with general-purpose tools, they can cause unnecessary damage, resulting in unnecessary repair costs. That’s because they’re not designed to handle something as delicate as a bearing. Use special tools to maintain the condition of bearings when handling, installing, or removing them. Some examples of these specialized tools include:

• • • Bearing puller
    • Bearing assembly kit
    • Injector kit
    • Hydraulic nut
    • Induction heater

These tools have been specially developed to ensure a smooth installation and removal process while minimising the risk of bearing damage.

• Prevent corrosion

When bearings are exposed to moisture for a long time, they may rust or corrode. When this happens, the bearing fails prematurely, causing problems with machine performance and productivity. This will increase your operating costs.

It is important to wear gloves when handling bearings, as even hand sweat can cause bearing corrosion. It’s a good idea to use waterproof grease as a lubricant to form a protective barrier in wet environments. If you are dealing with a very corrosive environment, it is best to look into bearings made of different materials, such as ceramic bearings.

• Watch out for danger signs

After the bearing has been installed, it must be kept abreast of it, being aware of any abnormality or poor performance. If you notice excessive noise, increased temperature, or unusual vibrations, there is a problem. If any abnormality is found, the bearing should be removed immediately and then analyzed.

By following these tips, you can ensure deep groove ball bearings stay in good shape and continue to function.

Overall, deep groove ball bearings are a good choice for most applications. They are durable and reliable. They are capable of bearing both radial and axial loads can operate at high speeds and are extremely durable. Additionally, deep groove ball bearings are relatively inexpensive, making them a popular choice for many applications.
