What does the +0.50mm sizing mean for these bearings?

The +0.50mm sizing indicates that these bearings are designed to be used with a crankshaft that has been machined down by 0.50mm from its original size. This is common during engine rebuilds to correct for wear or to achieve specific internal clearances.

What is the advantage of King's three-layer bearing technology?

King's three-layer technology combines a strong steel backing with a specialized aluminum alloy and a durable bearing material. This design helps manage oil flow effectively, resist corrosion, reduce friction, and ultimately improve bearing longevity.

Are these bearings suitable for high-performance applications?

While designed for durability and proper oil control, it's important to ensure these bearings meet the specific requirements of your engine build. Always follow manufacturer installation guidelines and torque specifications for optimal performance and reliability.

About this part

Product Details

If you're rebuilding the engine in your BMW M20 or M60, getting the connecting rod bearing clearance just right is critical for oil flow and engine longevity. This set from King Engine Bearings is built to help you achieve that precise fit, especially when you're working with a crankshaft that's been machined to a +0.50mm undersize.

King uses a unique three-layer material technology that helps manage oil flow and prevent bearing failure. The inner layer is a strong steel backing for support, the middle layer is a specialized aluminum alloy that's designed to bond well and resist corrosion, and the outer layer is a bearing material that's engineered for low friction and durability. This combination helps ensure consistent oil pressure and reduced wear, even under demanding conditions. Because these bearings are sized at +0.50mm, they are intended for use with a crankshaft that has been machined down by that amount to correct for wear or to achieve a specific build specification.

When you're putting an engine back together, especially one with a performance or rebuild focus, using well-built bearings like these is a smart move. Make sure to follow the manufacturer's installation instructions carefully, paying close attention to oil clearances and torque specifications to ensure a successful rebuild.
