For the vast majority of rotary motion of mechanical systems and lot of other systems, the bearing can be said to be a necessity.
But today, demand for bearings of the auto industry is the largest.Each car has an average of 100-150 bearings and 25-30 bearings on each motorcycle.
Under the background of annual production of 93 million cars and annual production of 140 million motorcycles, demand for bearings in the international market trend of substantial growth and have continued to grow.

Japan Seiko (NSK) developed in the harsh environment can also achieve high reliability, "with high reliability seal ring bearings."

The wheel hub bearing is a component bearing which is designed as one of the components installed on the wheel and the parts mounted on the vehicle, which is usually installed in the nearest position of the road, easily stained with muddy water, and it is an important part of supporting body, so it requires high reliability. In recent years, with the promotion of environmental protection measures, there are CO2 emission reduction requirements, and the price of petrol is also rising, to improve the efficiency of the car as a matter of urgency, so the need for hub bearings to improve reliability while reducing friction.

Japan Seiko by changing the seal Ring section shape, in the current main lip of the external side of the supplementary lip, to prevent the mud immersed in the lip movement, to achieve the original 1.5 times times the water resistance, and reduce the water accumulation of space, so that slurry is not easy to accumulate. At the same time, by computer analysis, the surface pressure distribution of the lip of the seal ring is optimized, and the friction loss of the original hub bearing is realized after the supplementary lip is added.

At present, Jinan Baisite Bearing Co.,Limited for the wheel hub bearing models listed below:
