Cam Outer
Mack

The cam outer is a structural member in a cam-driven mechanism, providing a surface for mating with an inner cam or follower. This part governs timing, displacement, and the conversion of rotational motion into controlled linear movement within hydraulic or pneumatic subsystems. It is manufactured to tight tolerances to ensure smooth engagement, minimize play, and reduce vibration. Proper fit and alignment are essential to prevent premature wear and to maintain consistent cycle timing. Routine inspection for scoring, corrosion, or misalignment helps sustain performance.
