Hub Bearings

Hub Bearings
1st wheel bearing is a double row angular contact ball bearing incorporating an integral outer ring and two separable inner rings or a double row tapered roller bearing. In order to ensure the preloading after assembly to meet the requirement ,the bearing clearance is set in advance. There is no need to use the spacer to adjust the preloading at assembly. And the wheel bearings are self-owned seals so the labour cost is reduced.

The characteristic of 2nd Generation Hub units are fewer parts. lighter weight and conveniently assembly. The flange of outer lane is connected by bolts to the suspension (inner ring rotating) or to the brake disc and steel ring (outer ring rotating)

3rd Hub unit contains an outer ring with a flange which is connected to the suspension and an inner ring with a flange which is connected to brake disc and steel ring. There is no need to adjust the position at assembly. The ABS sensor which can measure the vehicle speed and prevent wheel-slip is integrated to the Hub unit. The swaging technology is used to self-locking half inner ring. This swaging mode (non-driving wheel) can reduce the volume. weight and cost.
