Thrust ball bearings and spherical bearings performance comparison
1: Thrust ball bearings features:
1, one-way thrust ball bearings can only support axial load in one direction from the axis of its ring structure, with a full set of ball seat and maintain the frame. Which axis ring installed in the shaft seat ring bore hole bigger than the shaft, seat hole can not be grinding.
2, two-way thrust ball bearings can withstand import axial load in both directions on both sides it has a ring with the axial channel and the two seat, two components with a ball cage.
3, thrust ball bearings import operation, the ball outside the channel due to centrifugal force, Ji Xiang, easy to scratch that temperature is too high, not high speed ball with the channel in order to ensure access, we must impose the minimum axial force.
2: Insert bearing features:
1, to advance into the external sphere ball bearings good enough grease, the ball bearing with spherical seat directly on the shaft. This avoids the process of installing the bearing unit of imports of hazardous substances into the bearing interior.
2, insert ball bearings are on both sides with a heat-resistant, oil resistant rubber seal ring and the combination of steel dust cover. Dust cover assembly in the bearing inner ring with inner diameter with rotating, can effectively prevent external foreign matter into the bearing interior, and can resist external pressure to protect bearings.
3, bearing diameter and bearing with spherical outside diameter, with automatic transfer between cardiac function can compensate for the installation of the error of the axis do not coincide and the installation of the bottom deformation.
4, the import needs in and around bearing were hardened and been part of the normal quenching, the assembly set screws of the inner end of the elongation at high temperatures while maintaining local tempering toughness and impact resistance.
