51406 Thrust Ball Bearing
Comprising of caged ball bearing element and pair of shaft housing washers (bearing shaft washer and housing washer), Thrust Bearings are designed primarily to support axial loads at contact angles between 30 and 90, normal contact angle is 90. Just as with radial bearings, these bearings differ according to the type of rolling element they use. With thrust bearings, it is necessary to supply an axial preload in order to prevent slipping movement between the bearing's rolling element and raceways. Axial loads can be supported in only one direction, radial loads cannot be accommodated.
Spherical roller and needle roller versions are also available.
