• Reduced overlay thickness prevents fatigue in high-stress applications

Performance Features:

• Higher eccentricity compensates for bore distortion in high-revving engines
• High crush factor ensures maximum bearing retention and heat transfer
• Oil grooves extend around both bearing halves for improved lubrication
• Engineered for excellent conformability, embedability, and fatigue resistance
