What does the '0.5' in the part number mean for these bearings?

The '0.5' indicates that these are 0.5mm undersize bearings. This means they are designed for use when the crankshaft journals have been machined down by 0.5mm, typically during an engine rebuild to clean up wear or damage.

What is the benefit of silicon bi-metal aluminum construction?

Silicon bi-metal aluminum offers a well-built material that balances strength and wear resistance. This makes it a solid choice for supporting the rotating crankshaft in medium-load engine conditions.

Are these bearings compatible with all 2002-2008 Mini Coopers?

This specific bearing set is designed for the W10B16A and W11B16A engines found in the 2002-2008 Mini Cooper. It's important to confirm your engine code to ensure proper fitment for your vehicle.

About this part

Product Details

This is a main bearing set from King Engine Bearings, specifically designed for the W10B16A and W11B16A engines found in 2002-2008 Mini Cooper models. Main bearings are crucial components that support the crankshaft within the engine block, allowing it to rotate smoothly and efficiently. This set is built with a silicon bi-metal aluminum material, which offers a good balance of strength and wear resistance for medium-load engines.

King Engine Bearings has been specializing in engine bearings since 1960, focusing on supplying well-built components. This particular set is 0.5mm undersize, meaning it's intended for crankshafts that have been machined to a smaller diameter during an engine rebuild. The lead-free composite construction is also an environmentally safe choice for your build.
