What does '0.5mm oversize' mean for these bearings?

This means the bearings are slightly larger than standard size. They are intended for use when the crankshaft journals have been machined down by 0.5mm to correct for wear or damage. Always measure your crankshaft journals to confirm the correct size needed.

What type of engine is this bearing set best suited for?

This bearing set is specifically designed for medium-load engines. The bi-metal aluminum construction and lead-free composite make them a solid option for many common vehicle applications.

Are these bearings environmentally safe?

Yes, these bearings utilize a lead-free composite material. This makes them an environmentally safe choice compared to older bearing technologies that contained lead.

About this part

Product Details

When you're rebuilding the bottom end of your engine, getting the right crankshaft main bearings is crucial. This set from King Engine Bearings is designed for medium-load engines and features a bi-metal aluminum construction. They are a lead-free composite, making them an environmentally safe choice. This particular set is 0.5mm oversize, which is important if your crankshaft journals have been machined down during a rebuild. King has been specializing in bearings since 1960, focusing on supplying well-built components for a wide range of vehicles.

These bearings fit a broad spectrum of vehicles, including popular models like the Ford Taurus, Mazda 6, and Lincoln LS. The bi-metal aluminum material offers good performance for everyday driving conditions. Because these are an oversize bearing, they are specifically intended for use when the crankshaft has been ground undersize to correct for wear or damage. Always confirm your crankshaft journal dimensions before ordering.
