  SB-T90 | CuSn8 wrapped bronze bush with through holes, ISO3547 standard, metric size  

The bearings are wrapped from a cold formed homogenous bronze CuSn8 (alternative CuPb10Sn10) with
exceptional material
properties. The standard sizes incorporate holes, which are dispersed in a special
way over the whole bearing 
surface. These holes 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 etc. 
where high load and slow movement occur.

  Bronze alloy    Chemical Composition (%)   Type
   CuSn8      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   

 


Features

1. Easy of fitting and lubricate
2. High load capacity
3. Excellent wear resistance with lower friction
4. High level thermal conductivity
5. Minimum overall dimensions
6. Chemical resistance
7. Extended service life and lubrication intervals than normal SB-090 type bearings
8. Free selection of lubricants
9. Collection of dust and rub off particles in the holes. 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. It can be fabricated into bushes, half bearings, flanged bushes, thrust washers, spherical bearing and so on.
