M16WKL25-103N
Camshaft
Bendix

This camshaft element is a fundamental part of the trailer braking actuation system, featuring a braking interface sized at 16.50 inches and an elongated head section for reliable engagement with the cam follower. It presents a spline diameter of 1.50 inches and 28 splines, with a counterclockwise rotation orientation and trailer axle applicability. The shaft geometry and material selection are optimized for high load conditions and extended service life, delivering consistent performance across numerous braking cycles. The head length is precisely controlled to maintain alignment with adjacent components, supporting predictable wear patterns and minimized runout. The assembly is designed for compatibility with standard mounting configurations and partners within the same cam family, enabling straightforward replacement during maintenance or axle refresh programs. Cross references are not listed, but VMRS 013-001-031 places this shaft firmly in the trailer camshaft category, highlighting its critical role in translating rotational input into controlled brake actuation. Category context 41394 reinforces its linkage within the trailer cam and shaft components family.
