Rod Ends

As an indispensable core component in the automotive industry, automotive bearings are widely used in multiple key systems of automobiles due to their high precision, high load-bearing capacity, and low friction characteristics, directly affecting the operational performance, safety, and durability of automobiles. ​

In the transmission system, bearings play an important role in transmitting power. Needle roller bearings, tapered roller bearings, and ball bearings are widely used in gearboxes. Among them, needle roller bearings, with their compact structure and high radial load-bearing capacity, are suitable for the rotational connection between gear shafts and housings, and can efficiently transmit torque in limited spaces; Conical roller bearings are commonly used at the input and output shaft ends of gearboxes to ensure stable positioning during power transmission, as they can withstand both radial and axial loads simultaneously. The main reducer and differential in the drive axle also rely on bearing support. The active bevel gear of the main reducer often uses a combination of tapered roller bearings to ensure gear meshing accuracy through preload adjustment. The differential housing is supported by spherical roller bearings or cylindrical roller bearings to adapt to differential motion during vehicle turning. ​

The application of bearings in the driving system is directly related to the smoothness and handling of the vehicle. Wheel bearings are a key component, and modern cars often use integrated wheel hub bearing units that integrate functions such as bearings, wheels, sensors, etc. This not only simplifies the installation process but also accurately monitors wheel speed, providing key signals for ABS anti lock braking systems. This unit usually adopts a double row angular contact ball bearing or tapered roller bearing structure, which can withstand the composite load of vehicle weight, driving force, and lateral force, maintain stable rotation during high-speed driving, and its sealing performance design can effectively resist external pollutants such as mud, water, dust, etc., extending its service life.
