Flanged plain bush Specification
Flanged plain bush, the Steel matrix, sintered bronze spherical powder in the middle, rolled PTFE and Pb mixture on the surface, which is the rolled sliding bearing. It has the characteristics of small friction coefficient, good wear resistance, good corrosion resistance and oil less lubrication. It has the advantages in reducing the cost, reducing the mechanical volume, avoiding biting shaft phenomenon and reducing the noise.

Flanged plain bush Application Feature
1. Without oil or less oil lubrication, applied in the place where can’t add the oil or is hard to refuel, without maintenance or less maintenance during using.
2. Good wear resistance, low friction coefficient, long service life
3. Distributed the stress on the wide surface of the contact to improve the bearing capacity of bearing with a proper elastoplasticity.
4. Similar static friction coefficient, eliminate low-speed crawling, to guarantee the mechanical working accuracy.
5. Make the machine reduce vibration, reduce noise, prevent pollution and improve working conditions.
6. Formed a Transfer film to protect the grinding axis without biting shaft phenomenon in motion.
7. Low hardness requirements for grinding shaft, the shaft can be used without conditioning treatment, reduce the processing difficulty of related parts.
8. Thin wall construction, light weight, reduces the mechanical volume.
9. Steel back can be plated a variety of metals, can be used in corrosive media; widely used in various mechanical sliding parts at present, for example: printing machines, textile machines, tobacco machinery, micro motors, automobiles, motorcycles and forestry machinery, etc.
