Product Details
Thrust Ball Bearing Thrust ball bearings are separable and their limit rotational speed is low. Structures: 1.51000 type single-direction thrust ball bearings, this type of bearing can only accommodate axial load on one direction and can control the axial movement on one direction of the shaft and housing. 2.52000 type double-direction thrust ball bearings, this type of bearings can accommodate axial load on double direction and can control the axial movement on double direction of shaft and housing. 3. 560000 type thrust angular-contact ball bearing, as this structure can carry axial load and radial simultaneously. Cage materials When the outside diameter is equal or lesser than250mm, thrust ball bearings generally adopt pressed steel sheet cages, when the outside diameter is more than250mm,it will adopt solid cages. Minimum axial load When the thrust ball bearing is operating, if the applied axial load is too small, the axial direction is not tightly pressed, then acted by centrifugal force, the steel ball will slip and displace and destroy the normal operation of the bearings. To avoid the occurrence of such case, an axial load, Famin must be applied when the thrust ball bearings is working. The calculating formula is: In the equation, Famin Minimum axial load (kN) A Minimum load constant N Revolution (r/min) Minimum load constant A is showing in the bearings dimension table. If the applied axial load is small, a spring must be used to preload the bearing. Permissible tilt angle The double supporting surface of thrust ball bearings should be parallel. The axis center line should be square with shell supporting surface, if this is not assured, it can compensate by adopting spherical housing washer and self-aligning washer. Tolerance The tolerance value of thrust ball bearings is showing in the section [the tolerance of rolling bearing". Dynamic equivalent axial l
