What does the 0.50mm undersize mean for my engine rebuild?

The 0.50mm undersize specification means these bearings are designed for a crankshaft that has been machined down by 0.50mm. This is a common practice during engine rebuilding to achieve proper oil clearance when the original bearing surfaces have wear or have been machined.

What type of engine is this bearing best suited for?

These bearings are ideal for medium-load engines. This typically refers to engines that are not constantly subjected to extreme stress, such as daily drivers or vehicles used for moderate towing or hauling.

Are these bearings environmentally friendly?

Yes, these bearings feature a lead-free composite material, making them an environmentally safe option.

About this part

Product Details

If you're rebuilding the engine in your 1986-2002 Ford Escort, especially if it's a medium-load application, these connecting rod bearings from King Engine Bearings are a solid choice. They are specifically sized at 0.50mm undersize, meaning they are designed to be used with a crankshaft that has been machined down by that amount to ensure proper clearance and oil film.

King specializes in bearings, and these are made from a lead-free, environmentally safe composite material on a bi-metal aluminum base. This construction is well-suited for engines that aren't constantly pushed to their absolute limits, offering reliable performance and durability for everyday driving and moderate use. Because they are a specialized component, ensuring your crankshaft has been properly machined to the 0.50mm undersize is key for a correct installation and optimal oil pressure.
