JTEKT has successfully developed wheel hub bearing units with low torque and high tightness in cold areas.

In recent years, in order to achieve carbon neutrality, the manufacturing environment led by the automobile industry,

It is more necessary than ever to reduce energy losses. The low torque of wheel hub bearing unit supporting automobile wheels has also become an indispensable technology directly related to fuel consumption.

On the other hand, nitrile rubber used for sealing part accounts for about half of the torque generated by hub bearing unit. It is used as sealing material in hub bearing unit and various fields, but its low friction property is contrary to the physical properties of rubber (such as strength, heat resistance, wear resistance, etc.), so how to realize the two properties at the same time has become a subject.

Generally speaking, nitrile rubber has certain advantages in oil resistance, wear resistance and tear strength, but its cold resistance is inferior to other rubber materials.

With the development of marketization, if the hub bearing unit produced by JTEKT will be used in a worse environment than at present, expanding the service temperature range of sealing rubber has become an important topic.

Loading position of sealing rubber (new product)

The rubber materials developed this time can be used not only in wheel hub units, but also in various industries, including other auto parts. JTEKT will continue to contribute to the realization of a low-carbon society.

The new products developed by JTEKT this time contribute to the realization of the United Nations sustainable development goals SDGs
