Product Description

Self-Lubricating Multilayer Composite Bushing

Carbon Steel + Copper Powder + (PTFE + Pb + Filler)

Carbon-based lead-free lubricating bearings Cylindrical PTFE Sleeve Bushes | VSB-10

VIIPLUS VSB-10 is backed with copper-plated steel with porous bronze sintered on the steel and polymes (PTFE+Pb) imbedded into the bores of the bronze. By combining the metals and the polymers together, its products are endowed with the lower friction coefficient and good capacity of anti-abrasion and self-lubrication. Moreover, the steel back is plated with a erosion-prevention layer. Products of VSB-10 series are widely applied in printing, weaving and tobacco producing machines, gymnastic equipments, etc.

 

 

Carbon-based lead-free lubricating bearings Cylindrical PTFE Sleeve Bushes have same features as the VSB-10, but without lead.

 

 

Typical application

Typicai applicaton
Application: the printing, woven, tobacco and gymnastic machinery, etc.
same application as the normal VSB-10, but much more for automotive industry, food industry, medicines, drink machines and so on which not allowed to use the lead and difficulty forming the oil film or need lubrication parts.
