Product Specification

Basis Information

Bearing bush is an important component used in mechanical equipment, which supports and guides the rotating shaft. It is widely used in automobiles, engineering machinery, ships, and various other industrial fields.

Product Usage

The bearing shells are used to support the bearings.When mechancial equipment is running,the contact surface between the shaft and the bearing will generate sifnificant pressure and friction.

Can provide you with whatever your areas of application: passenger vehicles, utilities or heavy goods vehicles.

1. Car: truck, road, bus, car, modified car and so on.

2. Construction Machinery: forklifts, earth moving machinery, compaction machinery, concrete machinery, etc.
3. The general petrochemical machinery: oil refining machinery, chemical machinery, gas compressors,textile machinery,paper machinery, printing machinery, etc.

Product Principle

The working principile of the bearing shell is based on knowledge of tribology and lubrication.Enable the shaft to rotate smoothly and reduce friction and wear.Through reasonable bearing design and correct lubrication methods,the efficiency and service time of mechanical devices can be improved,enabling them to operate normally.
