Fitment data not listed — send us your machine model or serial number to confirm.
Description
The main thrust bearing helps support the axial load generated by the reciprocating motion of the pistons. Typically located at the center of the crankshaft between the main bearing journals, it is designed to withstand the thrust generated by connecting rod movement. The main thrust bearing is located between the cams.
Features
- Built to exact specifications for durability and reliable performance
- The upper and lower halves are separated by a thin layer of lubricating oil, which helps reduce friction and wear
Applications
The main thrust bearing limits the front-to-rear movement of the crankshaft by keeping it within a specific range of motion.
