Product Details

The Clevite MS-1266A is a precision-engineered crankshaft main bearing set designed to deliver reliable performance and durability in automotive engine applications. This bearing set utilizes Clevite's legendary TriMetal construction, featuring a steel backing, aluminum alloy intermediate layer, and lead-tin-copper overlay for optimal load distribution and wear resistance.

Key Features:

  • TriMetal construction for superior strength and durability
  • Optimized groove design for proper oil film development and lubrication
  • Upper shell features 180-degree oil groove to supply connecting rod bearings
  • Ungrooved lower shells maximize oil film thickness for enhanced bearing life
  • Precision machined to tight tolerances for proper crush and retention
  • High-quality overlay material resists fatigue and wear
  • Engineered to maintain critical oil pressure to connecting rod bearings

Clevite bearings are manufactured using advanced materials and processes to ensure consistent quality and performance. The main bearing design balances the need to supply adequate oil to connecting rod bearings through the upper shell groove while maximizing load-carrying capacity in the lower shells. This configuration provides the best combination of lubrication, oil film strength, and bearing longevity for demanding engine applications.

Clevite is a trusted name in engine bearings, supplying original equipment manufacturers and the performance aftermarket with precision bearing solutions. Each bearing set meets or exceeds OEM specifications for fit, finish, and performance.
