steel backed bushings
high-performance steel-backed DU bushing, environmental protection is predicated on steel substrate, the center bronze powder, sintered spherical surface rolling four ethylene (PTFE) and a mix of green polymer material, rolling and sliding bearing. Product is lead-free environmental protection, wear-resisting performance is superb , plastic layer and a copper layer with high strength, fatigue resistance, impact resistant performance may be a great way for a plus .
Can be provided as form:
Non-standard products also are avalidable.
PTFE/Pb composition, 0.01-0.03mm,anti-abrasion material, which form a lubrication film to guard the shaft during machine operational .
bronze powder layer,0.2-0.35mm, which further strengthen the mixture of the plate and PTFE layer. Bronze have good thermal conductivity. It can transfer the warmth which produce
during operation more quickly.
Low-carbon steel, which improve load capacity and warmth transfer.
Copper/tin plating layer, anti-corrosion.
Working under oil free or minim oil condition,maintenance free or simply
need a couple of maintenance.
Resist abrasion,low coefficient of friction long operating life.
Operating in -190℃~+280℃.
Easy to mending,low-noise,non-pollution.
Thin wall,light,which can reduce the rolume of machine.
Forming a transferred film during operation to guard shaft.
Low demand to the shaft even no surface hardness treatment,which lower
the cost of the mating components.
No absorption to water/oil,small coefficient of thermal emption,good
thermal conductivity and size stability.
The back of the steel strip are often plated with various metal,anti-
The products now are utilized in sliding components of various
machines,such as auto machines,piston pump,gear pump,textile
machine,auto-sides machine,injection machine,sports machine,office
