Perfect Circle Connecting Rod Bearing Undersize

Perfect Circle undersize connecting rod bearings, also called rod bearings or con rod bearing sets, are made for engine rebuilds. They are meant for crankshafts that have been machined to a smaller journal diameter. They help restore proper oil clearance and smooth rotating assembly operation.

Key Features:

• Undersize design for use with reground or machined crankshaft rod journals
• Precision-manufactured bearing shells for consistent wall thickness and accurate fit
• Built to help maintain correct oil film and clearance between the bearing and journal
• Backed by the Perfect Circle brand, a long-standing name in engine sealing and bearing products for rebuilders and professional shops
• Suited to engine rebuild and overhaul projects

Measure the crankshaft journals and confirm the oil clearance during assembly. Choose the correct undersize for the engine build. Quality bearings help the engine run quietly and last longer after a rebuild.
