Product Description

Bronze Wrapped Bearing with Through Holes

The bearings are wrapped from a cold formed homogenous bronze (CuSn8) 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.

Low Maintenance Polymer Plain Bearings , CuSn8P Oil Filled Bronze Bearing
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 CSB-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...


  • Wrapped bronze sliding bearing
  • CuSn8P 
  • Low-maintenance
  • With perforations


  • High load capacity and stability at low abrasion. Because of perforations lubrication clearances are reduced to a minimum!


  • CuSn8P
