Description
High-Performance Crankshaft Support for Cummins K50 & KT50 Engines
The Cummins 3018213 Main Bearing Set is a premium-grade engine component engineered to deliver exceptional durability and reliable crankshaft support in heavy-duty applications. Designed specifically for Cummins K50, KT50, KTA50, and QSK50 diesel engines, this main bearing set is an essential choice for professional engine rebuilds and overhauls.
This bearing set features a 0.030-inch (0.75 mm) oversize configuration. When a crankshaft journal is reground during servicing to eliminate wear or scoring, standard-size bearings can no longer maintain the correct oil clearance. Installing this precision-manufactured oversize bearing set restores the exact clearance required for optimal oil pressure, reducing friction and preventing premature engine failure.
