ACL Bearings 5M1913H-STD Race Series Main Bearing Set Standard Size

The ACL Race Series 5M1913H-STD represents the unique combination of design, metallurgy and engineering that delivers what drivers expect from high performance trimetal engine bearings. This standard size main bearing set is engineered for Honda F20C and F22C engines, commonly found in 2000-2009 Honda S2000 applications.

Key Performance Features:

• High strength overlay plate with reduced thickness for improved fatigue properties
• Increased crush for improved bearing retention
• Elimination of flash plating on the back of the bearings to improve heat transfer
• Increased eccentricity to compensate for bore distortion at high rpm and assist in hydrodynamic oil film formation
• 3/4 grooved main bearings to optimize bearing load carrying surface area and oil flow
• Enlarged ID chamfers on bearing edges to accommodate large fillet radius on performance crankshafts

Technical Specifications:

• Bearing Material: F780
• Bearing Size: Standard (STD)
• Max Shaft Size: 55mm (2.1654 inches)
• Max Tunnel Size: 60.02mm (2.363 inches)
• Oil Clearance Range: 0.012mm to 0.072mm (0.0005" to 0.0028")
• Wall Thickness at Crown: 2.504mm (0.0986 inches)

Designed to withstand higher RPM conditions, ACL Race Series Engine Bearings are available for many of the popular 4, 6 and 8 cylinder applications. Race Series rod and main bearings are standard components in race engines that have set records and won championships across multiple motorsports disciplines.
