RCB-650Solid Lubricant Embedded Bushings with graphite
Introduction
It has a backing made of bronze with particular formulation supported by certain angle and density. The solid lubricants inlaid in the bushing are compounded with precision. It's used in successive casting machine, mineral mountain machinery, shipping, steam turbine etc. |

| Solid bronze turned bearings |
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.
