     Product Description:

     Bronze 650 high-strength brass bearings with embedded solid lubricant.

     Brone 650 material is made of strong cast brone based metal with special solid lubricants 


     The base metal withstands high load and the solid lubricants provide self-lubrication. 

     The bearing shows excellent performance without pre-lubrication under conditions of extreme 

high/low temperature with low speed.

     The material provides a maintenance-free bearing solution, particularly for high load, 

intermittent of oscillating motion. 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.

     It is widely used in automotive products line, water engineering……
