Description
Overview:
The Main Bearing (Output Side) RHP LRJ1.1/8 is a genuine Villiers component for the Villiers C30 Industrial Engine (OEM No. 31378V). It is a precision ball bearing made from hardened bearing steel, designed to support the crankshaft on the output side, keep it running true, and reduce friction under load. The LRJ1.1/8 designation indicates a 1 1/8 in (28.6 mm) shaft bore, giving the correct interference fit for the C30 crank journal. Supplied as unused old stock, it may show light tarnish or storage marks, but remains mechanically sound and fit for service. This bearing helps maintain engine efficiency, protects mating components, and restores smooth operation on engines used in industrial and workshop environments where reliability matters.
