Steel Backed Du Bushings,high performance DU rings in steel, environmental protection is based on a steel substrate, medium bronze powder, a spherical sintered surface rolling four ethylene (PTFE) and a mixture of green polymer material, bearing and sliding bearing . The product is lead-free environmental protection, the wear resistance performance is excellent.https://www.viiplus.com
Self-lubricating Bearings Type
Non-standard products are also avalidable.
PTFE / Pb composition, 0.01-0.03 mm, anti-abrasion material, which forms a lubrication film to protect the shaft during the machine in operation.
bronze powder layer, 0.2-0.35 mm, which further strengthens the combination of the steel sheet and the PTFE layer. Bronze has good thermal conductivity. It can transfer the heat it produces
during operation more quickly.
Low-carbon steel, which improves load capacity and heat transfer.
Copper / tin coating layer, anti-corrosion.
Oil-free or minimal oil condition, maintenance-free or fair
need a little maintenance.
Resists abrasion, low coefficient of friction, long service life.
Operating in -190 ℃ ~ + 280 ℃.
Easy to mend, silent, non-polluting.
Thin, light wall, which can reduce the volume of the machine.
Formation of a film transferred during operation to protect the tree.
Low demand on the tree, even without surface hardness treatment, which reduces
the cost of the coupling components.
No absorption to water/oil,small coefficient of thermal emption,good
thermal conductivity and size stability.
The back of the steel strip can be plated with various metal,anti-
The products now are used in sliding components of different
machines,such as auto machines,piston pump,gear pump,textile
machine,auto-sides machine,injection machine,sports machine,office
