Power tool bearings are mechanical components that support and constrain moving parts of a power tool. The bearings allow the moving parts to rotate smoothly and with little friction.
There are many different types of power tool bearings, each with different advantages and disadvantages. The most common types of power tool bearings are ball bearings, roller bearings, and sleeve bearings.
Ball bearings are the most common type of bearing and are used in a wide variety of power tools. Ball bearings have a round shape and are made of metal. They are very durable and can withstand a lot of wear and tear.
Roller bearings are another common type of bearing. Roller bearings have a cylindrical shape and are also made of metal. Roller bearings are less durable than ball bearings but can withstand more radial (side-to-side) force.
Sleeve bearings are the least common type of bearing. Sleeve bearings have a cylindrical shape and are made of plastic or metal. Sleeve bearings are not as durable as ball or roller bearings but can withstand more axial (up-and-down) force.
