Crankshaft Main Bearing

Main bearings are important components of crankshafts, which are the main driving shafts of internal combustion engines that receive reciprocating motion from the pistons and convert it to rotary motion. Together, crankshafts and connecting rods transform piston reciprocating motion into rotary motion.


  • Cat® parts are manufactured to precise specifications and are built for durability, reliability, productivity, less environmental impact, and reuse
