Features of Bearing Hubs

The rolling part of the bearing hub is mainly composed of high-precision ball bearings, and some are combined with balls. Usually, there are 2 bearing, 3 bearing and 4 bearing, which represent the number of bearings inside the hub, of which 3 bearing and 4 bearing is mainly used on the rear hub.

feature is:

1. There is a support frame inside the bearing hub, which has high stability and precision;

2. The number of installed balls is small, the friction force is small, and the wetness is high, which will sacrifice durability and comfort;

3. Radial, that is, the vertical rigidity is very high, but the lateral rigidity is weak;

4. No maintenance is required, it can be replaced directly after wear, and the maintenance cost is low;

5. Professional tools are required for installation and disassembly. Improper methods will damage the bearings.
