Perfect Circle CB542P10 Connecting Rod Bearing Undersize - 0.010

The Perfect Circle CB542P10 is a high-performance P-Series connecting rod bearing engineered for demanding engine applications. This precision-manufactured bearing features a 0.010" undersize specification, making it ideal for engines with slightly worn crankshaft journals that have been machined to restore proper clearances.

Advanced Performance Design:

• Tri-metal construction with hardened steel backing for exceptional strength and durability
• Copper-lead alloy intermediate layer for load-bearing capability
• Electroplated babbitt metal overlay provides superior slipperiness and conformability
• Higher eccentricity and increased crush factor to compensate for connecting rod bore distortion in high-RPM applications
• Full 360-degree oil grooves on both halves ensure optimal lubrication throughout the bearing surface
• Extra-thin overlay design reduces friction and heat buildup

Key Features:

• Designed specifically for high-revving engines where RPM causes connecting rod bore narrowing
• Dowel holes in lower sections accommodate aluminum connecting rods
• Precision-engineered to meet or exceed OEM specifications
• Part of the renowned Clevite 77 performance bearing family

Perfect Circle P-Series bearings deliver professional-grade performance and reliability for engine rebuilds, restorations, and performance upgrades. The tri-metal design offers properties not typically found in standard replacement bearings, ensuring long-lasting protection for your engine's critical rotating assembly.
