About Automobile Bearings

Wheel bearings are critical in the sense that they are designed to support the complete loads of the vehicle and are therefore made of wear resistance and corrosion, impact and high temperature resistant materials. In modern vehicles, the most commonly used are the double row ball bearing or the tapered roller bearings which bear disabling and axial loads simultaneously in an effort to stabilize and keep the vehicle safe while in use.

Automobile engines integrate parts that move through bearings such as crankshafts, camshafts and turbo chargers. The primary purpose of engine bearings is to cover the spaces between rotating elements, thereby minimizing wear from the heat generated by friction This is because it has to operate under high pressure forwards and backwards at high speeds hence the material has to be wear and heat resistant.

Gearbox bearings support the transmission shaft and those of the gear sets in movements while ensuring smooth and efficient operation of the gearbox system. Bearings need to sustain highly dynamic rotating movements and intricate load scenarios with axial and radial force. Usually, ball and roller bearings are the two types of bearing used in the gear boxes. Ball bearings are applied in operations with light and high speed rotating loads and roller bearings work best when applied in low speed high load operations.

The suspension system of a car requires steering knuckle bearings and swing arm bearings. And the bearings used in the suspension system are mainly responsible for transmitting the movement between the suspension system and the wheels, ensuring the sensitivity and accuracy of the steering system. Therefore, the bearings inside must have high fatigue resistance, accuracy, durability and sealing.
