PROTRANS™ BRAKE S-CAM SHAFTS
PROTRANS™ BRAKE S-CAM SHAFTS
Protrans™ brake s-camshafts are designed for a range of commercial vehicle applications. Forged using high quality carbon steel to meet SAE 1045 standard, these brake s-camshafts feature hardened critical contact points to increase reliability, wear life and corrosion resistance.
The brake camshaft is a part of the brake linkage for heavy duty truck air brakes. The camshaft is the component responsible for spreading the brake shoes apart. In air brake systems, the brake chamber expands and the operating rod pushes on the (brake) slack adjuster. As the operating rod pushes on the slack adjuster, it rotates around the shaft of the S-Cam. When the camshaft is rotated the eccentric shape of the cam head pushes the brake shoes apart. The brake shoes separate and cause friction between the brake lining and the brake drum. It is this friction that slows and stops the vehicle.
