A wheel bearing is a crucial part of the wheel assembly that connects the wheel and the axle. It is a set of steel balls (ball bearings) or tapers (tapered bearings), held together by a metal ring. It enables the wheel to rotate smoothly with a minimum of friction. Wheel bearings are safety critical components designed to sustain radial and axial loads caused by gravitation, acceleration, breaking & cornering forces, so they need to be replaced when they stop working properly.
These are different from the engine bearings, as there is no constant source of lubrication for the wheel bearings, which means they need to be tight enough to keep away water and road dust. They also support the entire vehicle weight while driving, which is why they suffer a lot of abuse from rough roads, potholes, as well as lateral forces when turning.

Maintenance free wheel end trend
1、Serviceability 2、 Lightweight
3、Reachability 4、Warning Function
5、Emergency 6、High efficiency & mass production
7、InterchangeabilityStrong bearing capacity, low noise and high rotational speed.
hub assembly is a non-adjustment and maintenance-free wheel end designed by high precision non-adjustment bearings, combined long life oil seal, special variable nut locking mechanism of shaft head and front axle visual inspection function on front wheel cover. Comparing with ordinary axle wheel end, the most unique design is that the HL hub assembly build an elastic adjustment partition between the two hub bearings
Wheel bearings Application
Heavy duty truck、Agricultural machinery、Petrochemical engineering、Transmission parts、Automobile、Engineering machinery
Wheel bearings play an important role within the drivetrain of any vehicle, as they provide the first connection between the moving and static areas of the car. A bearing – in its simplest form – is a friction reduction device placed within something like a wheel to aid efficiency of rotation. This is achieved as rolling produces much less friction force than sliding.
