J08CT Diesel Engine Bearing
The engine is the heart of the car, which determines the power, economy, stability and environmental protection of the car. In recent years, with the development of the automotive industry, the operational requirements of automotive equipment have been increasing requirements for automotive bearing performance.
The diesel engine bearing is designed with high-strength materials to ensure its long-term stable operation and resistance to damage. Its smooth surface reflects the exquisite manufacturing technology, ensuring accuracy and stability, and improving the efficiency and reliability of mechanical equipment. Additionally, the lightweight design of the bearing contributes to energy savings.
High-strength Bearing Ability:
The bearing ability is a crucial indicator in bearing design, directly impacting the reliability and service life of mechanical equipment. Generally, the harder the inner material of the engine bearing, the greater its bearing ability. A well-designed bearing can significantly improve its bearing ability. If it lacks sufficient bearing ability, it may fail prematurely and disrupt the normal operation of the motor. Due to the outer surface is treated, which increases the hardness and strength of the engine bearing to enhance the bearing with fatigue resistance. This shows that it with high strength is essential to ensure the motor’s normal operation and long-term stability.
Wear-resistance:
The wear-resistance of bearings is achieved through special coatings and technologies. Metal coatings, for example, can significantly improve the wear-resistance of motor bearings, reducing the friction. If it is not wear-resistant, its surface will be severely damaged, leading to disruptions in normal operation. The reasonable shape can well make the the bearings with even pressure to improve the wear-resistance. Therefore, they are becoming increasingly popular due to their ability to reduce energy consumption.
Very Suitable for Diesel:
It is a crucial support component for the crankshaft, effectively bearing the weight and power to maintain stable operation. With a large contact area with the crankshaft, it can distribute pressure and reduce friction, ultimately extending the lifespan of both the bearing and crankshaft. Additionally, the use of bearings can reduce noise and vibration, ensuring the diesel engine operates normally. The special design and manufacturing techniques employed in bearing production can also reduce energy loss, improve fuel efficiency, and lower emissions and power consumption.

The automobile engine is the device that provides power to the car and is the heart of the car, which determines the power, economy, stability, and environmental protection of the car. In recent years, with the development of the automotive industry, the operational requirements of automotive equipment have been increasing requirements for automotive bearing performance.
Common types of bearings for automotive engines
Automotive engine bearings usually use the structure of steel backing + wear reducing alloy, wear-reducing alloy commonly used in the three categories of pasteurized alloy, copper-based alloy, and aluminum-based alloy.
1. Pasteurized alloy is divided into tin-based and lead-based two types, pasteurized alloy fatigue strength is low, the allowable specific pressure and the working temperature are low, generally used for strengthening the lower degree of gasoline engines.
2. Copper-based alloys are divided into two categories: lead bronze and copper-lead alloys.
3. Aluminum-based alloys are divided into two categories: high tin alloys and low tin alloys, aluminum-based alloys are currently the most widely used in internal combustion engine crankshaft shafts.
Alternator bearings
Alternator bearings are single-row sealed ball bearings, mainly subject to centripetal force, required to be able to operate reliably under the condition that the speed exceeds 2000r/min and the temperature is greater than 180℃.
Air conditioner compressor electromagnetic clutch bearing
Air conditioner compressor electromagnetic clutch bearing is double row angular contact ball bearing, outer ring rotation, air conditioner pulley speed up to 7000~13000r/min, maximum temperature 160℃, material as above, cage from ordinary single spherical pocket hole part into a cylindrical surface.
Tension pulley and idler pulley bearing
Tension pulley and idler pulley bearings are high performance sealed ball bearings, the former acts on the loose side of the synchronous drive belt, the latter acts on the tight side of the synchronous conveyor belt, the material is basically the same as above, the cage is available in engineering plastic, also available in 08 steel or 10 steel manufacturing, the seal is made of ACM or FPM (fluorine rubber).
Water pump shaft bearing
Water pump shaft bearing is generally a double row ball bearing, radial size is smaller than the general bearing. It is essentially a simplified structure of the double-branch bearing system, two bearing support without the inner ring, rolling body raceway directly on the shaft, two bearing support outer ring made of a whole, the two sides of the ring with seals sealed, its roller is usually made of high chromium bearing steel, shaft, outer ring material using carburized steel or high chromium bearing steel manufacturing.
How to choose the lubrication of bearings?
The lubrication of bearings can be divided into oil lubrication and grease lubrication. Oil-lubricated bearings generally choose type bearings, grease lubricated bearings generally choose dust cover or rubber seal.
The seal set is suitable for higher temperature or better use environment parts, the seal is divided into contact seal and non-contact seal two, contact seal dustproof performance is good, but the starting torque is large, non-joint seal starting torque is small, sealing performance is not good.
