What is the main function of crankshaft main bearings?

Crankshaft main bearings sit between the crankshaft and the engine block. Their primary job is to support the crankshaft and allow it to rotate smoothly while maintaining proper oil clearance.

What does 'STD' mean for these bearings?

STD refers to 'standard' size. This means the bearings are manufactured to the original equipment manufacturer's (OEM) specifications and are intended for use when the crankshaft journals are not worn beyond their service limits.

Are these bearings suitable for a rebuilt engine?

Yes, this ACL main bearing set is a popular choice for engine rebuilds. Ensuring proper clearance and lubrication is critical for the longevity of a newly rebuilt engine.
