Steering gear bearing is a key component of the steering system of an automobile, belongs to the category of steering system bearings, mainly used in the internal structure of the steering wheel of motor vehicles, and has the main function of supporting the steering gear. Its outer ring is often made of rubber to provide a soft connection between the body and the shock absorber; the bearing must withstand axial and radial loads and require periodic replenishment of lubricant.
This bearing supports steering flexibility by accurately supporting rotating parts, and when used in conjunction with deep groove ball bearings, can improve steering sensitivity and accuracy. With the development trend of new energy vehicles, the new type of pendulum bearing adopts a self-aligning outer ring design, which can automatically compensate for the rotation angle of the worm and reduce the friction torque, effectively eliminating extraneous steering noise. It is suitable for heavy vehicles and electric vehicles with rack-and-pinion electric power steering. Bearing cracking can lead to irregular wheel alignment, so reliability must be ensured through a quality management system.
Depending on the design and application, power steering system bearings are divided into several types, the most common being ball bearings and roller bearings.
A ball bearing consists of an inner ring, an outer ring, steel balls and a cage and is capable of withstanding significant radial and axial loads. A roller bearing consists of an inner ring, an outer ring, rollers and a cage and is suitable for applications with higher loads and higher speeds.
