Metallic Self-Lubricating Bearings, The Copper Sleeve, Bronze Graphite Guide Bushes
 

Cast bronze with graphite oilless bearings

650# material is made of strong cast bronze based metal with special solid lubricants embedded. The base metal withstands high load and the solid lubricants provide for self-lubrication. The bearing shows excellent performance without pre-lubrication under conditions of extreme high/lower temperature with low speed.
This material provides a maintenance-free bearing solution, particularly for high load, intermittent of oscillating motion.

1.May work without oil for long perlod
2.Extremely high load capacity,good anti-wear and lower friction
3.Particularly appropriate for low speed and high load
4.Suitable for reciprocating,oscillation or Intermittent motion whereoil film is hard to be formed
5.Good chemical resistant and anti-corrosion characteristics
6.can be used in wide range of temperature from -40°c~+300°c

Typical Application
This kind of bearing can be applied under dry, high temperature, high pressure, corrosive, water or other chemical environments when no oil can be introduced.
Now is widely be used in automotive products line, water engineering, dam gate, plastic industries, successive casting machines, steel rollers in metallurgy industry, mineral machines, ships, turbo generators, hydraulic turbines and injection molding machines...
