Bushings And Sleeves

(Total 6 Products)

As for the ternary ceramic cobalt-tungsten alloy, 2B bushing, bushing and sleeve developed by our company, their superior wear resistance, corrosion resistance and crack resistance are 5-6 times better than the similar product. (sink roller sleeve and arm sleeve can be used continuously for about 30 days, stable roller sleeve and arm sleeve can be used continuously for about 60 days)


The new material IB developed by our company overcomes the defects of sinking roller and stabilizing roller, such as short service life, slime on the surface of shaft body, serious corrosion, low hardness and changeability. The mechanical property of IB new material is 4-5 times better than 316L material and the wear resistance is 3-4 times better than 316L material.

Bushings And Sleeves
Bushings and sleeves are two common connecting parts in machinery. Their function is to protect and fix other parts.
Bushing is a part that fits on the shaft or in the hole, usually made of metal or plastic. The inner diameter of the bushing usually mates with the outer diameter of the shaft or hole, and the outer diameter mates with the external part. The bushing can reduce the friction between the shaft and the hole and prevent wear and damage. It can also adjust the matching gap between the shaft and the hole to improve assembly accuracy.
A sleeve is a part that fits over a bolt or nut, usually made of metal. The inner diameter of the sleeve mates with the outer diameter of the bolt or nut, and the outer diameter mates with the external part. The sleeve can protect the bolt or nut from corrosion and damage from the external environment. It can also increase the contact area of the bolt or nut and improve the strength and stability of the connection.
Generally speaking, bushings and sleeves are connectors used to protect and fix other parts. They play an important role in mechanical assembly.
