Good To Know

Q: What does 'STD' stand for in engine bearings? A: Standard (STD) means the bearings are designed for crankshafts that have not been ground down or undersized during machining.

Q: Why is proper bearing clearance critical? A: Proper clearance ensures correct oil film thickness, preventing metal-to-metal contact and keeping the crankshaft rotating smoothly.

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