  SB-090 | CuSn8 wrapped bronze bush, diamond oil pockets, ISO3547 standard  

The bearings are wrapped from a cold formed homogenous bronze CuSn8 (alternative CuPb10Sn10) with exceptional material properties. The standard sizes are fitted with diamond shaped lubrication indents in the bearing surface. These indents serve as lubricant reservoirs to rapidly build up a lubrication film at the start of movement and thereafter reduce the running friction. The material is suitable for construction and agricultural machinery applications.

  Bronze alloy   Chemical Composition (%)   Type
   CuSn8P    Cu=91.3%  Sn=8.5%  P=0.2%  Pb=0%  Zn=0%    Lead Free
   CuPb10Sn10    Cu=Balance. Sn= 9~11%, Pb=9~11%    With Lead



Suitable for dry running with a low coefficient of friction, low wear rate, good sliding characteristics, the transfer film created will protect the mating metal surface. Suitable for rotary and oscillating movement, high chemical resistance, lower absorption of water and reduced swelling. Also performs well with lubrication.
Typical Applications

This type of bushing is widely applied in hoisting machines and other construction machines, automobiles, tractors,trucks, machines tools and some mineral engines. It can be fabricated into bushes, half bearings, flanged bushes, trust washers, spherical bearing and so on.
