PEEK Sleeve Shock Absorber Bearing For Hydraulic Machinery Long Operating Life
1. Product Description
PEEK Sleeve Bushings For Gear Unit , Hydro Engine & High Pressure Injection Pump are consists of steel backing, sintered porousbronze layer and sliding layer of modified PEEK. Oil sockets were formed on the surface of sliding layer. This product has low friction coefficient at high temperature and good anti-corrosion.Therefore, it is widely used in engineering.

3. Application
PEEK Sleeve Bushings For Gear Unit , Hydro Engine & High Pressure Injection Pump are widely used in pump ,guiding part of high quality shock absorbers,lathes and lifting parts of tanks and rockets etc.
4. Advantages
The PEEK sleeve bearing has the characteristics of high bearing capacity, good seismic resistance, stable and reliable operation, low noise and long life, even has good performance when it works under water lubrication or little oil lubrication.Its wear resistance is quite outstanding compared with ordinary material bearings.Its form is simple, large contact area, if the lubrication is maintained well, this wear resistant sleeve bearing will be very good, the bushing life will be very long.
