The analytic comparison of capability features between thrust ball bearing and pillow block ball bearing

A: Thrust Ball Bearings features:

1, i.e.one-way thrust ball bearings are only bear a direction of the axial load on the structure by shaft circle, seat ring and ball with full of the cage. Among them, the shaft circle installed in shaft, seat ring hole hole bigger than shaft circle, seat ring aperture can not conducted grinding.

2, the two-way thrust ball import bearings can withstand the two directions of the axial load it with a two sides in gully axis, two seat ring ring and ball, two groups of strip maintains a module.

3 import bearings, thrust ball by centrifugal force ball operation, to channel the lateral, easy to squeeze a scratch that high temperature, unfavorable high-speed operation in order to guarantee the ball and channel contact, must exert minimum axial force.

2: the characteristic: the pillow block ball bearing

1, want beforehand inject enough foreign pillow block ball bearing, high-quality grease set-contained ball bearing installed directly in shaft. This can avoid import bearings unit in installation process of harmful substances into the bearings inside.

2, the two sides are pillow block ball bearing with heat-resistant, prevent oil rubber sealing ring and steel dust cover combined sealing. Dust cover assembly in bearing inner circle diameter rotate together with inner circle, can effectively prevent external foreign body in bearing, and can resist the external internal pressure protection bearings.

3 and the bearing outer diameter and bearings for spherical coordinates, with automatic adjust between members, can compensate for the installation errors are no superposition and installation underside axis of the deformation.

4, import bearing inner circle around the race-way and hardening part and needed by normal quenching, assembly tight set screw the inner circle elongation end is by high temperature and maintain local tempering toughness and impact resistance.
