electric bicycle thrust ball bearing 51101 51102 51103

Product Description

Thrust ball bearings with high-speed operation can withstand the design of the thrust load, with a rolling ball rolling groove with a ring-shaped ring. As the ring for the seat cushion, therefore, thrust ball bearings are divided into flat cushion and aligning spherical cushion type two types. In addition, this bearing can withstand axial load, but can not bear the radial load.
Feature editing
1. There are two types of one-way, two-way
2. In order to allow the installation error, whether it is one-way or two-way, you can choose spherical self-aligning spherical seat cushion or spherical seat type.
3. High-quality steel - the use of the bearing life can extend the maximum 80% of the ultra-clean steel
4. High Grease Technology - NSK's lubricant technology expands grease life and improves bearing performance
5. High-grade steel ball - quiet and smooth at high speed
6. Use the ring in the option to allow installation errors.
Usage
Applicable to only one side of the axial load, low speed on the parts, such as crane hooks, vertical pumps, vertical centrifuges, jacks, low speed reducer and so on. Bearing shaft ring, seat ring and rolling body is separate, can be assembled separately.
