📘 Technical Reference & Bearing Size Information

📏 Crankshaft Main Journal Size Reference

Bearing Size	Journal (Inch)	Journal (mm)
Standard (STD)	2.6772″	68.00 mm
.010″ Undersize	2.6673″	67.75 mm
.020″ Undersize	2.6575″	67.50 mm

STD bearings suit unmachined crankshafts. Undersize bearings are used after crankshaft journals have been machined. This differs from pistons, which are supplied as oversize when the cylinder bore is machined larger.

Important: .010″ and .020″ undersize bearings are designed specifically for crankshafts that have been professionally reground. Always confirm your required size with your engine machinist before ordering to ensure correct oil clearances.

Measurements are provided as a guide only. Always measure crankshaft journals accurately and refer to the relevant OEM service manual to confirm specs before ordering.
