King Engine Bearings BMW N20B20 (Size +0.75mm) Main Bearing Set

This King Engine Bearings main bearing set is built with a high-performance overlay material, offering improved durability for your BMW N20B20 engine. These bearings are specifically sized at +0.75mm, meaning they are 0.75mm larger in diameter than standard, which is crucial for engines that have been machined to a larger crankshaft journal size during a rebuild.

King uses a unique tri-metal construction that combines a steel backing for strength, a porous bronze interlayer for good embeddability, and a lead-tin-over-copper overlay for reduced friction and wear. This combination helps to manage heat and oil flow effectively, supporting the crankshaft under demanding conditions. The precise sizing ensures a proper fit and oil clearance when installed on a machined crankshaft, which is essential for proper engine lubrication and longevity.

When rebuilding your N20B20 engine, using bearings that are correctly sized for your machined crankshaft journals is critical. This set is designed to meet the needs of a performance-oriented rebuild, ensuring your engine runs smoothly and reliably.
