1. Different functions:

 

1, the shaft sleeve plays the role of sliding bearing, fixing and positioning.

 

2, bushing is used for mechanical parts, in order to achieve sealing, wear protection and other parts.

 

Two, different material requirements:

 

1, sleeve: the requirements of low hardness and wear, sleeve inner hole by grinding scraping, can achieve higher precision, there must be lubricating oil groove on the inner wall.

 

2, bushing: soft metal, rubber, nylon and non-metallic polymer, the texture of these materials is relatively soft, low price and cost. The bushing withstands vibration, friction and corrosion in all kinds of harsh working conditions to protect the wrapped parts, which is easy to replace after damage, low cost and good economy.

 

Three, different applications:

 

Bushing: packaging machinery, textile machinery, mining machinery, metallurgical machinery, printing machinery, tobacco machinery, forging machinery, all kinds of machine tools and exchange machinery transmission connection.
