RCB-650 Solid Lubricant Embedded Bushings with graphite

RCB-650 Solid Lubricant Embedded Bushings with graphite

Basic characteristics

Machined Cast bronze bearings offer technically and economically favourable bearings solutions. High loading capability, low weight, good corrosion resistance. Roncan Bearing can offered different type bronze alloys according to the life time, service etc. The tolerance is much tighter than wrapped bronze bushes.。
