What does 'undersize' mean for these bearings?

An undersize bearing is designed for a crankshaft that has been machined down to a smaller diameter. This set is 0.010 inch undersize, meaning the crankshaft journals have been turned down by that amount to correct wear or damage.

What is the main function of connecting rod bearings?

Connecting rod bearings sit between the connecting rod and the crankshaft. Their main job is to create a low-friction surface that allows the rod to rotate around the crank while maintaining a thin film of oil for lubrication and cooling.

Are these bearings sold individually or as a set?

This product is sold as a set, which includes all the necessary bearings for the connecting rods on a typical engine.
