Brand New DNJ® Crankshaft Main Bearing Set

DNJ® Crankshaft Main Bearing Sets are precision-engineered components designed to support and stabilize the crankshaft in engines, ensuring smooth and reliable rotation under high load conditions. Each set typically includes upper and lower bearing shells, and depending on the application, thrust bearings to control crankshaft movement and maintain optimal oil clearance for effective engine lubrication. Manufactured to meet or exceed OEM quality standards, ensuring professional-grade reliability and performance under demanding engine conditions.

DNJ® Crankshaft Main Bearing Sets are constructed using advanced bi-metal or tri-metal materials to ensure optimal strength and durability. The typical construction includes a robust steel backing for structural integrity, a copper-lead or aluminum alloy intermediate layer for excellent load-carrying capacity, and a soft, wear-resistant overlay such as Babbitt or aluminum-tin to promote embeddability and reduce friction. This layered composition is designed to withstand high operating pressures and deliver long-lasting, reliable performance in a wide range of engine conditions.

DNJ® also offers a wide selection of related engine components including connecting rod bearings, thrust washers, and complete engine rebuild kits. These products are engineered to the same high standards, ensuring compatibility and performance consistency across all critical engine assemblies.

With precision engineering and top-tier materials, DNJ® Crankshaft Main Bearing Sets deliver exceptional performance and long-lasting durability.
