ACL Bearings 5M2152H-001 Race Series Main Bearing Set Oversize - 001

The ACL Bearings 5M2152H-001 is a high-performance Race Series main bearing set engineered for Ford Kent 1500-1600cc engines, including Lotus Twin Cam and Ford Cosworth BDA, BDB, BDC, and BDD applications. This .001" oversize bearing set is designed for demanding motorsports applications where reliability and performance are critical.

Advanced Engineering Features:

• Multi-layer construction with precision-engineered overlay, barrier, lining, and high-tensile steel backing
• Enhanced bearing eccentricity compensates for bore distortion during high-speed operation
• Increased crush improves bearing retention through higher radial contact pressures
• Superior heat dissipation through improved thermal transfer to the housing
• Manufactured to exacting micron-level tolerances for consistent wall thickness and crush
• High-strength overlay plate with reduced thickness for improved fatigue resistance

Technical Specifications:

• Standard shaft size: 53.988-54.000mm (2.1255-2.1260")
• Standard tunnel size: 57.683-57.696mm (2.2709-2.2714")
• Identical halve design for simplified installation
• .001" oversize specification for machined crankshafts

ACL Race Series bearings are proven in championship-winning engines across multiple motorsports disciplines, from sport compact drift racing to NHRA and IHRA competition. The unique combination of advanced metallurgy, precision manufacturing, and race-focused design delivers the endurance and capability required where standard bearings cannot perform.
