Truly wheel Hub Bearing Co.,Ltd mainly specializedin the manufacturingof First,Second and Third Generation Wheel hub bearings.lts bearing are with heavy carrying capacitance,high sealing performance,and have features as high reliability and long usage life.All of them have past the 180 hours plasterers test,250 hous usage life test and 130 hours high temperature test (According to German Standard).

Reduced fuel consumption and CO2 emissions

Replacing the tapered rollers contact line with the balls contact points and eliminating rib friction reduces bearing friction by approximately 50%. This wheel bearing thus makes an important contribution toward improving fuel economy and reducing emissions.

Low weight

The face splines save a significant amount of weight and enable fuel savings and a reduction in CO2 emissions. The system weighs around ten percent less than a conventional bearing. On four wheels in a vehicle,this involves a weight saving of over one kilogram.

Ease of mounting - a significant cost advantage

The wheel bearing module with axial splines is appealing due to its ease of mounting. The self-centering axial gear teeth are fixed in place on the axial journal by means of the central screw in the assembly. The bearing remains completely clearance-free in the gear teeth during operation. Regardless of whether the vehicle travels 1,000 or 100,000 kilometers, the bearing won t budge during the entire operating life!

Increased driving dynamics

50 % more torque transmission for a significant increase in driving dynamics:The torque transmission with the axial splines is considerably higher compared with radial splines, mainly due to the larger diameter of the pitch circle of the gear teeth.
