📘 Technical Reference & Bearing Size Information

📏 Conrod (Big-End) Journal Size Reference

Bearing Size	Journal (mm)	Journal (Inch)
Standard (STD)	54.00 mm	2.1259″
.25mm Undersize	53.75 mm	2.1161″
.50mm Undersize	53.50 mm	2.1063″

STD bearings suit unmachined crankshafts. Undersize bearings are used after conrod journals have been machined.

Important: .25mm and .50mm undersize bearings are designed for crankshafts that have been professionally reground.
They are not intended to compensate for minor wear on a standard-sized shaft.
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 conrod journals accurately and refer to the relevant OEM service manual to confirm or cross-reference bearing and journal sizes before ordering.
