The product
is made of high quality low-carbon steel with sintering
porous bronze as its interlayer, with the compound of
POM as its surface. It can offer the good load capacity
and wear-resistant. It is applied to vehicle chassis,
forming machine tools, metallurgical machinery, mining
machinery, hydraulic industry and rolling steel industry,
etc. Because of without lead, the product is accord
with environment protection.

BIMETAL BUSHING
|
|
It is
made of high quality low-carbon steel, sintered copper
alloy of CuPbSn10, the alloy surface is rolled to
diamond oil grooves. The special lubricant is embedded
in grooves. It has good lubricating and corrosion
resistance property, it can work in the condition
of little of oil or none of oil. It is particularly
applied to high temperature, water solution and the
occasions where cannot be added oil.
