Cam
Bendix

This cam type concentrates on the essentials of drum brake actuation, providing the essential engagement geometry that translates rotational motion into linear shoe movement. It shares the VMRS code 013-001-031, aligning with a broad ecosystem of components designed to fit conventional camshaft assemblies on trailer and heavy duty axle configurations. The dimensioning highlights a standard 16.50 inch brake size with a 1.50 inch spline diameter and a 28-spline drive interface, enabling reliable engagement with the corresponding actuator hardware in typical service fleets. Clockwise rotation remains compatible with common installation orientations, supporting straightforward replacement in many on road and off highway configurations. The category 41394 context emphasizes a family of brake actuation parts that emphasize durability, precise timing, and consistent performance under high load and high temperature scenarios. When selecting replacements, technicians reference VMRS mappings and cross references as needed to ensure seamless integration with existing yokes, studs, and mounting patterns, while maintaining consistent operational characteristics during braking events.
