Perfect Circle CB745P30 Connecting Rod Bearing Undersize - 030

The Perfect Circle CB745P30 is a high-performance connecting rod bearing designed for small journal Chevrolet engines. This precision-engineered bearing features a .030" undersize specification, making it ideal for crankshafts that have been machined to restore proper clearances during engine rebuilds.

Key Features:

• Tri-Metal construction with hardened steel backing, copper-lead alloy intermediate layer, and electroplated babbitt overlay
• P-Series design with high crush factor for maximum bearing retention
• Higher eccentricity to compensate for bore distortion in high-revving engines
• Extra-thin overlay thickness engineered to prevent fatigue under demanding conditions
• .030" undersize for proper fitment on machined crankshaft journals
• Suitable for Chevrolet V8 265, 283, 302, and 327 engines, as well as inline-6 and inline-4 applications

The P-Series bearings represent Clevite's traditional tri-metal design that combines exceptional strength, conformability, and embedability. The steel backing provides structural integrity, while the babbitt overlay delivers critical surface characteristics including low friction and excellent conformability. This bearing is sold individually and is ideal for performance rebuilds, heavy-duty applications, and engines subjected to high RPM operation.
