Camshaft
Bendix

This dimensionally robust variant is tailored for drum brake actuators requiring a longer reach. It presents a width and height of 109 mm each, a length of 410 mm, and a camshaft length of 16.12 inches, all supporting a 1.50 inch spline and 28 spline teeth. The 28‑tooth pinion arrangement provides precise torque transfer and minimized runout, essential for even shoe wear and uniform contact pressure across the drum. The geometry accommodates mid to large drum housings and ensures reliable actuation timing when installed with standard Bendix hubs and drive components. By design, it integrates with the same 28‑spline mating interface used across multiple assemblies, simplifying cross‑reference in fleets that operate mixed model brake sections. VMRS code 013-002-029 categorizes this unit within the actuation family for planning and inventory control. In practice, users gain predictable pedal response, consistent braking force distribution, and extended component life in heavy‑duty applications, including long‑haul, construction, and vocational service, where timing accuracy and linkage integrity are critical.
