SBM TYPE
SBM-10 . SBM-11 . SBM-20
This is a material designed for use where a high wear resistance is needed, even when low or high temperature are present, as much as heavy loads. In comparison to similar materials, this product keeps a relatively low coefficient of friction. The self-lubricating layer is a peculiar mixture of sintered bronze and special solid lubricants.
The backing materials used for this product are carbon steel, stainless steel and bronze. We can produce any dimension for any type of special plain bearings, flanged bearings, thrust washer or sliding plates and shaped tapes according to drawings.
Normally, this material does not require any lubrication, but it can be used with hydrodynamic lubrication.
