Cast Bronze Bearings with Graphite

Cast Bronze Bearings with Graphite(YF-500)
 
Structure
 
YF-500 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 self-lubrication.The bearing shows excellent performance without pre-lubrication under conditions of extreme high/low temperature with low speed.This material provides a maintenance-free bearing solution, particularly for high load, intermittent of oscillating motion.
 
Features
 
●Long-term use without maintenance;
●Designed for high static load and dynamic load;
●Has a low coefficient of friction and smooth, no ”sticky” phenomenon;
●Resistant to dust, corrosion resistance, impact resistance and resistance to edge load capacity; 
●Metal substrate has good shock absorption;
●Be able in a wide temperature range;
●Suitable for reciprocating, rotary and oscillating so frequent and difficult to form a film starts the occasion;
●Has a very low wear rate, long service life.
