Good To Know

Q: What is a standard (STD) bearing size? A: Standard size bearings are designed for factory crankshafts that have not been ground down or machined to undersized specifications.

Q: Why is proper oil clearance critical for these bearings? A: Correct oil clearance allows a thin film of pressurized oil to isolate the rotating crankshaft from the bearing shell, preventing catastrophic metal-on-metal contact.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
