Clevite MS-2202A-.75MM Engine Crankshaft Main Bearing Set

The Clevite MS-2202A-.75MM is a high-performance engine crankshaft main bearing set designed for demanding automotive applications. This precision-engineered bearing set features .75mm undersize dimensions to accommodate reground crankshafts, making it an essential component for engine rebuilds and performance upgrades.

Key Features:

• TriMetal bearing construction for superior strength and durability
• Optimized 180-degree upper shell grooving for maximum oil film thickness
• High crush design ensures positive bearing retention
• Reduced overlay thickness prevents overlay fatigue and hen tracking
• Precision tolerances for proper clearance and fit
• .75mm undersize for use with reground crankshafts

Performance Engineering:

Clevite main bearings utilize advanced grooving technology to balance oil delivery with bearing protection. The upper main shells feature a 180-degree groove that efficiently supplies oil to connecting rod bearings while maintaining optimal oil film strength. The lower shells are ungrooved, allowing the crankshaft to develop a thicker oil film for improved load capacity and extended bearing life under high-performance conditions.

Application:

This main bearing set is ideal for street performance, racing, and heavy-duty applications where reliability and durability are critical. The undersize dimension accommodates crankshafts that have been machined .75mm below standard diameter, providing proper clearances after journal refinishing.
