Thrust ball bearings are classified into those with flat seats or aligning seats depending on the shape of the outer ring seat (housing washer). They can sustain axial loads but no radial loads. For Single-Direction Thrust Ball Bearings, pressed steel cages and machined brass cages are usually used The cages in Double- Direction Thrust Ball Bearings are the same as those in Single-Direction Thrust Ball Bearings of the same diameter series.
A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. ... However, they can tolerate some misalignment of the inner and outer races.
Bearings Reduce Friction. Bearings are constrained elements used to reduce the friction of certain moving parts in a machine or device. This is done by replacing sliding friction with rolling friction. ... Roller bearings are used for heavier loads than ball bearings.
