Wheel Bearing

Wheel bearings are important parts installed on the wheels of vehicles to support the rotation of the wheels. It is mainly composed of inner ring, outer ring, rolling elements and cage.The inner ring is a metal ring fixed on the wheel shaft, and the outer ring is a metal ring fixed on the wheel bearing seat. The rolling elements are usually steel balls or rollers, which roll between the inner and outer rings to reduce friction and resistance and enable the wheel to rotate smoothly.The cage is used to maintain the position of the rolling elements and prevent the rolling elements from contacting and rubbing against each other. The cage is usually made of metal or plastic, which has certain elasticity and wear resistance.The main function of the wheel bearing is to support and rotate the wheel, reduce friction and resistance, and improve the driving efficiency and stability of the vehicle. At the same time, it can also withstand the weight of the vehicle and the shock and vibration of various road conditions.The life and performance of wheel bearings are affected by many factors, including load, speed, lubrication and maintenance. Regular inspection and maintenance of wheel bearings and timely replacement of severely worn parts can prolong their service life and ensure the safety and reliability of the vehicle.
