ACL Bearings 5M8353-.50 Race Series Main Bearing Set Oversize - 50mm

The ACL Race Series 5M8353-.50 main bearing set is designed for high performance race engines requiring .50mm oversize crankshaft journals. These race bearings feature tri-metal construction with lead, tin, copper and nickel for superior strength and seizure resistance, making them ideal for demanding motorsports applications.

Key Features:

• Multi-layered tri-metal copper alloy construction that blends characteristics to provide high strength and excellent seizure resistance
• 3/4 grooved main bearings to optimize bearing load carrying surface area and oil flow to the conrod bearings
• High strength overlay plate with reduced thickness for improved fatigue properties
• Elimination of flash plating on the back of the bearings to improve heat transfer through the bearings and to maximize the grip between the bearings and its housing
• Increased eccentricity to compensate for bore distortion at high rpm and to assist in the formation of hydrodynamic oil films
• Enlarged ID chamfers on bearing edges where required to accommodate large fillet radius on performance crankshafts
• Tight consistent wall tolerances to help you maintain consistent clearances

ACL Race Series performance engine bearings are recognized as a premier brand throughout the motorsports world, with bearings that are standard components in race engines that have set records and won championships.
