  SB-09G | CuSn8 wrapped bronze bush, diamond indents filled with GRAPHITES, metric size  

These are similar to the SB-090 range, except there are solid GRAPHITE embedded into the diamond shaped lubrication indents on the bearing surface, which provide good lubrication conditions at the start
up stage, even 
with a lack of oil. It can be used in construction machinery, gear boxes, automotive
clutch parts etc.

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



1. Easy of fitting and lubrication
2. High load capacity
3. Excellent wear resistance with lower friction
4. High level thermal conductivity
5. Minimum overall dimensions
6. Chemical resistance
7. Can work under dry/marginal lubrication for short period, lower friction factor at initial moving Initial pre-lubrication at assembly is required...
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.
