Product Description

Bronze bushing with good abrasion and corrosion resist bimetal sliding bushing

 

 

Specifications:

 

Features of Bushing

Maintenance-free!

No lubrication required (PTFE composite)

Minimum wall thickness, minimum space requirements

Accommodation of heavy loads

Wide range of temperatures

Good sliding properties

High wear resistance

 

Description:

 

Oilless bearing (bushing) takes steel plate as a substrate and is a kind of wrapped sliding bearing by

 

agglutinating spherical bronze powder inside the middle part and rolling the mixture of PTFE (PTEE) and

 

lead on the surface. It has the characteristics of small friction coefficient, wear-resisting, corrosion

 

resistance and oil-free lubrication. Using this product can reduce costs, reduce mechanical volume, avoid

 

bearing seizure phenomenon and reduce mechanical noise. The product has been widely applied in the

 

sliding parts of various machinery, such as printing machine, elevator, spinner, tobacco machine, body-

 

building, instrument, hydraulic pressure van, micro electrical machinery, solenoid valve, automobile,

 

motorcycle and farm & forestry machinery and so on.

 

1, Non-oil lubrication or less lubrication

 

2, Low maintenance, with better abrasion resistance

 

3, Low friction index and anti-aging.

 

Roughly introduction:

 

Materials

 

1. PTFE with mixture 0.01~0.03mm

 

2. Porous bronze 0.2~0.3mm

 

3. Steel backing 0.7~2.3mm

 

4. Tin-plating 0.005mm or copper plating 0.008mm
