How Angular Contact Ball Bearings Improve Efficiency in Machinery?
Angular contact ball bearings are a common type of rolling bearing designed to support radial and axial loads. Machines that use angular contact ball bearings are more efficient than those that do not because the bearings allow the parts to rotate smoothly and quickly.
Angular contact bearings have a ring shoulder removed from the inner or outer ring. This allows more ball replenishment, providing greater load capacity and higher speed capability than comparable deep groove bearings.
They are commonly used in applications requiring high precision and high speed, such as aircraft, automobiles, dental drills, and power tools. Angular contact ball bearings perform well in demanding applications such as pumps, compressors, and machine tool spindles – often at high speeds, with poor lubrication, and contamination.
This article will introduce the types, advantages, and working principles of angular contact bearings. It also discusses the steps to install it.
What are the types of Angular contact bearings?
Angular contact bearings’ choice depends on specific application requirements such as load capacity, speed, accuracy, and space constraints.
There are several types of angular contact bearings, including:
Single Row Angular Contact Bearings
These bearings have a single row of balls and are designed to accommodate radial and axial loads. They are used in a variety of applications such as machine tool spindles, pumps, and gearboxes.
Double Row Angular Contact Bearings
These bearings have two rows of balls and are designed to accommodate heavy radial and axial loads. They are typically used in applications requiring high radial and axial stiffness, such as machine tool spindles and printing presses.
Four-point contact bearing
These bearings are uniquely designed to accommodate radial and axial loads in any direction. They are typically used in applications requiring high axial loads and limited space, such as robotics and medical equipment.
Thin Section Angular Contact Bearings
These bearings have a thin section and are designed for applications where space is limited. They can accommodate radial and axial loads and are commonly used in aerospace and defense applications.

Radial Ball Bearings Versus Angular Contact Ball Bearings
Radial ball bearings and angular contact ball bearings are two types of ball bearings that are commonly used in various applications. Although both types of bearings are designed to support radial and axial loads, there are some differences between them.
The features of Radial ball bearings
Primarily designed to support radial loads perpendicular to the axis of rotation.
Designed with deep grooves for stability and support.
The load-carrying capacity is lower than that of angular contact ball bearings.
Usually have a lower operating speed than angular contact ball bearings.
May not be suitable for applications requiring high axial stiffness.
The features of Angular contact ball bearings
Designed to support radial and axial loads, which makes them suitable for applications requiring high load capacity.
Have a more complex design enabling them to handle radial and axial loads.
Has a higher load capacity than radial ball bearings.
Can run at higher speeds than radial ball bearings.
Offer high axial stiffness which makes them suitable for applications requiring precise positioning and precision.
In summary, radial ball bearings are suitable for applications that mainly require radial loads and are simpler in design, while angular contact ball bearings are suitable for applications that require both radial and axial loads and are more complex in design, providing higher load capacity and Higher performance, speed capability. Bearing selection depends on the specific requirements of the application.
How do angular contact bearings work?
Angular contact bearings work by using a series of balls positioned at an angle to the axis of the bearing. When a load is applied to the bearing, the balls roll between the inner and outer ring raceways, distributing the load evenly across the bearing, providing high load capacity, high speed capability and high axial stiffness, which means that they Holds its position even under load. This makes them suitable for applications requiring precise positioning and accuracy.
How to select the right angular contact bearing?
When selecting an angular contact bearing, the main considerations revolve around speed, load type, load magnitude, seal type, tolerances, and bearing size:
Speed: When choosing an angular contact ball bearing, it is important to consider the operating speed needed, lubrication method, and load capacity. Speed capabilities vary depending on these factors. When reviewing bearing options, be sure to evaluate each aspect closely in order to select the option that best meets your needs.
Load: Angular ball bearings boast impressive durability, enabling them to withstand both radial and axial loads. End users should evaluate the requirements of the application when selecting between single-point, double-point, or four-point angular ball bearings; factors such as type, direction and amount of load must be taken into account. Additionally, static and dynamic radial load capacity should also be considered in order to arrive at the best solution.
Lubrication and Seal Type: Relubrication is the process of applying oil or grease to an open or shielded seal. For oil and grease, a pre-lubrication phase is typically used with shielded or hermetic seals. Solid lubricants can also be used, usually in closed designs that are based on polymers.
Size: Select the bearing size based on load type, load capacity, shaft size, or housing size.
How to install an angular contact ball bearing?
Installing angular contact ball bearings involves several steps to ensure proper installation and prevent damage to the bearing.
The following are the general steps for installing angular contact ball bearings:
Clean Surfaces: Before installing bearings, ensure that the surfaces of the shaft, housing, and bearings are clean and free of any debris or contamination.
Install The Bearing: Carefully install the bearing onto the shaft, making sure it is properly aligned and seated.
Apply Lubricant: Apply an appropriate lubricant to the bearings to ensure smooth operation.
Tighten Locking Mechanism: If the bearing has a locking mechanism, such as a lock nut or lock washer, tighten it to the recommended torque specification.
Verify Fit: Verify proper fit by inspecting bearings for any signs of misalignment, play, or excessive play.
Test Turn: Turn the bearing to make sure it runs smoothly without any excessive noise or vibration.
Securing Bearings: If necessary, secure bearings with retaining rings or other fasteners to keep them from loosening during operation.
Summing it Up
Angular contact ball bearings are a type of bearings that help improve mechanical efficiency. They are designed to support high radial loads and axial loads in both directions. Angular contact ball bearings are often used in applications requiring high precision and speed.
