Difference Between Linear Bearing and Oilless Bush

1. What is the difference and selection between linear bearing and oil-free bushing?

 

The difference between the two: the bushing is of sliding friction, with large resistance and poor feel, but with large load and low price.

 

The linear bearing is equipped with steel ball, which is of rolling friction, low resistance, good feel, but low load and high price.

 

Both options: linear bearings should be available on the gearshift mechanism. Linear bearings are widely used in foreign automobiles

 

2. What is the difference between bearing, bushing and shaft sleeve?

 

Bearings are divided into sliding bearings and rolling bearings according to different friction types; The bushing can be understood as a sliding bearing, which acts as isolation lubrication between the shaft and the hole; The shaft sleeve usually refers to the connection between the shaft and other parts, which does not necessarily play the role of a bearing. Rolling bearings or bushes can be installed in the shaft sleeve. Of course, the shaft can also be directly installed in the low-speed field;

 

3. What does the bearing bush do?

 

Bearing sleeve: the ring sleeve that plays the role of gasket is used in the valve application field. The sleeve is in the bonnet. Generally, PTFE or graphite and other anti-corrosion materials are used for sealing. The sleeve made of antifriction material in sliding bearing is also called bearing sleeve and bushing. It is usually cast on the inner surface of bearing pads, mainly to reduce costs and save valuable anti-wear materials. Thickness 0.5-6mm, for large or important bearings. The bearing bush is mainly used to replace the wear of the shaft. In addition, it can support the shaft operation, reduce friction and wear, and reduce vibration.
