The Connecting Rod Bearing (Part No. 612600030020) is an original equipment (OE) precision wear component produced by Weichai Power, designed for use in heavy-duty diesel engines within the Weichai WD and WP series. Commonly referred to as the "small bearing" or "conrod bushing," this critical engine part serves as the sliding interface between the connecting rod big end and the crankshaft journal.

Engineered for high-load operation under extreme pressure and temperature conditions, this bearing ensures smooth rotational motion while maintaining hydrodynamic oil film integrity. It plays a vital role in reducing friction, preventing metal-to-metal contact, and protecting both the crankshaft and connecting rod from premature wear or catastrophic failure such as bearing seizure ("burned bearing") or crankshaft damage.
