ACL Bearings 5M1706P-.50 Race Series Main Bearing Set Undersize - 0.50mm

ACL Bearings has earned a global reputation for robust metallurgy, quality, precision, innovation and performance in engine bearing manufacturing. This main bearing set is designed to provide precision crankshaft support during engine rebuilds and performance applications.

Undersize Specification:

This bearing set is 0.50mm (approximately 0.020 inch) undersize, specifically engineered for crankshafts that have been ground or machined during rebuilding. Undersized bearings allow you to achieve the correct oil clearance when crankshaft journals have been ground down during a previous rebuild or due to wear.

Race Series Features:

• Trimetal design features a high-strength overlay plate with reduced thickness for improved fatigue resistance
• Hardened steel backs on all bearings to improve support and assist with bearing retention in the housing
• Increased crush for improved bearing retention and heat transfer
• Increased eccentricity to compensate for bore distortion at high RPM and assist in hydrodynamic oil film formation
• Tight consistent wall tolerances to help maintain consistent clearances

ACL performance engine bearings are specially made to provide dependability under higher RPM conditions and feature improved eccentricity to compensate for bore distortion at high-speed operation. For over 70 years precision engine bearings have been manufactured in Tasmania, Australia, and ACL has been a major OEM supplier to the Australian and International automotive industry.
