Trailer Cam
Bendix

This large trailer cam assembly combines a long actuator bore interface with a 28-spline input, delivering precise control over braking timing in demanding trailer applications. The specified dimensions—Length 26.25 in, Head Thickness 0.69 in, Spline Diameter 1.50 in, Main Journal Diameter 1.62 in, and Brake Surface Diameter 12.25 in—define a substantial engagement surface and a robust mounting footprint suitable for high-load conditions. The 28-spline quantity indicates a high torque transfer capability and smooth rotary-to-linear conversion, minimizing backlash and wear in the actuation pathway. The VMRS 002-014-001 categorizes this component within trailer actuation subsystems, confirming broad compatibility with Bendix trailer cylinder assemblies and matched cam followers. Its specification set supports extended service life in fleets that demand precise brake timing, consistent release and engagement, and reliable performance across temperature and humidity variations. The trailer-focused category reflects applicability to a wide range of highway and regional operation profiles, contributing to safer, more predictable braking behavior during routine and emergency stops alike.
