The function and purpose of Main Bearing Set.

A lack of proper lubrication for your internal engine components can result in intense friction and heat and lead to total engine failure. The moments where your engine's main caps meet the crankshaft are where all the friction and heat come from, and that is why your Buick Rainier main bearings are installed there. These main bearings are made from a composite metal called Babbitt (iron, zinc, copper, aluminum, and more), because its gall-resistant surface makes it ideal to act as a buffer in the space between the crankshaft and main bore in your Buick Rainier. When properly lubricated, very little friction is created around the engine main bearings and they will last the life of the vehicle.
