Cast Bronze Bearings with Graphite
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.
