Cam
Bendix

This cam style in the braking actuation family emphasizes consistent timing and robust construction for strong, reliable shoe actuation in drum brakes. With a VMRS designation of 013-001-031, it integrates seamlessly into standard cataloging and replacement workflows, supporting fleet maintenance across a range of trailer and tractor configurations. The 16.50 inch brake size, along with a 1.50 inch spline diameter, and 28 spline drive interface, ensures a snug fit with common cam assemblies and drive yokes used in heavy duty braking systems. Rotation direction is clockwise, matching conventional installation practices for most trailer axles. The category 41394 placement confirms its role within a broader set of cam and actuation components designed for durability under load, heat, and vibration. In field service, technicians value consistent engagement geometry and interchangeable mounting patterns that simplify inspection, replacement, and preventative maintenance in busy maintenance bays or at roadside service stops.
