Clevite MS-1715AL-.50MM Engine Crankshaft Main Bearing Set

The Clevite MS-1715AL-.50MM is a high-performance engine crankshaft main bearing set designed for demanding applications. This bearing set features precision-engineered construction with optimized oil film characteristics for maximum durability and performance.

Advanced Bearing Design:

This main bearing set utilizes a 180-degree groove in the upper shell, providing optimal oil distribution to connecting rod bearings while maintaining maximum load-carrying capacity in the lower shell. The upper main shells feature grooves to supply connecting rods with oil, while the lower shells remain ungrooved to develop a thicker oil film for improved safety margins and extended bearing life.

TriMetal Construction:

Clevite's legendary TriMetal bearing construction delivers exceptional strength and durability. The precision-engineered design features high crush for maximum retention and reduced overlay thickness to prevent overlay fatigue. This construction ensures consistent performance under high-load conditions.

Performance Features:

• Optimized 180-degree upper shell grooving for balanced oil delivery
• Ungrooved lower shells for maximum oil film thickness
• High crush design for superior bearing retention
• Reduced overlay thickness prevents hen tracking and fatigue
• Precision-manufactured to strict tolerances
• -.50MM undersize for use with reground crankshafts

Application Notes:

This bearing set is ideal for performance and racing applications where maximum bearing life and oil film protection are critical. The -.50MM undersize designation indicates these bearings are designed for crankshafts that have been ground 0.50mm undersize from standard dimensions.

Clevite main bearing sets are engineered to provide the optimal balance between oil supply to rod bearings and load-carrying capacity, ensuring reliable performance in high-stress engine applications.
