Product Details
Gearbox Anti Erosion Wrapped Bronze Bearing With Special Solid
Lubricant
It is made of Tin-bronze CuSn8P that is of high density. Its
surface is punched with oil sockets by certain angle and density.
There fills with special solid lubricant in the sockets, which
endows the products with fairly small friction coefficient.
Therefore, it can maintain a good lubrication capability when oil
is temporarily run out. In addition, It has good anti-fatigue and
load, anti-erosion and abrasion capacity. The products are widely
applied in conditions of heavier load but mediate running velocity,
such as on engineering machines, gearbox, and clutch on the
automotive vehicles, etc.
