ACL Bearings 5M2964H-.50 Race Series Main Bearing Set 0.50mm Oversized for Nissan SR20

The ACL Bearings 5M2964H-.50 Race Series Main Bearing Set is engineered for high-performance applications requiring 0.50mm oversized bearings. Designed specifically for Nissan SR20DE and SR20DET engines, these tri-metal performance bearings deliver superior durability and reliability under extreme conditions.

Key Features:

• 0.50mm oversized main bearing set for crankshaft machining applications
• High-strength tri-metal construction with advanced metallurgy for exceptional seizure resistance
• Manufactured to micron-level tolerances for consistent wall thickness and precise crush fit
• Elimination of flash plating on bearing backs improves heat transfer and maximizes retention
• Increased eccentricity compensates for bore distortion at high RPM
• 3/4 grooved design optimizes load-carrying surface area and oil flow to connecting rods
• Hardened steel backing provides superior support and bearing retention
• F780 bearing material designed to withstand high RPM, stress loads, and temperatures

ACL Race Series bearings are manufactured with precision measurement systems that ensure reliable fit and consistent clearances. The enhanced material composition, optimized dynamic thickness, improved heat conduction, and strategic oil groove distribution make these bearings ideal for engine builds, performance upgrades, and motorsport applications from drift racing to drag racing competitions.
