FRB-650 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.

Structure

FRB-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 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.
