Thrust bearings four point ball bearing, double row (column) angular ball bearings, double direction tapered and cylindrical roller thrust bearings, has recently also developed the brake roller bearing thrust bearing.
At four o′clock by ball bearings, double (single) when used as a thrust bearing of angular contact ball bearings, no radial load, correspond to the bore of the bearing to the other part of NSK bearings, their diameter must be larger than the bearing outer diameter 0.5 mm or so. Is smaller than the inner diameter of the bearing or roller diameter 0.5 mm or so.
Four-point contact ball bearings, installation do not use swaps, the isolation of the same model to prevent changes to the factory the axial clearance.
Thrust tapered roller and double direction thrust cylindrical roller bearings of the intermediate circle, bearings of the same type do not interchange to prevent change of axial clearance of the factory.
End face of thrust bearing inner ring must be taken when installing pressure and axial locking. To avoid relative rotation on the roll neck, roll neck wear of the mating surfaces, caused burns.
Brake roller thrust bearing is to be used by two axial positioning of bearing box, and adjust the axial clearance. When you install the bearing box, be sure that the inner and outer rings of NSK bearings and main bearings inner and outer rings of snapping. When axially on both sides of the rack when the bearing box, pay attention to the Elimination of import on both sides of the rack housing bearing boxes that might arise in the course of the axial direction of the shaft end.
