Tough, Durable and Reliable Camshafts 
The brake camshaft (or S Cam) is at the heart of the air brake system and it must be able to withstand the rigorous demands of heavy duty brakes. State-of-the-art technology is utilized to manufacture our brake camshafts. With CNC turret lathes and computer controlled heat treating equipment, these S Cams are made tough, durable and reliable. 

State-of-the-Art Camshaft Manufacturing Process 
Creating a quality brake camshaft requires forging the head of the cam to the correct specifications. A camshaft with an incorrectly manufactured, worn or damaged head can cause erratic brake operation. 
Therefore it is very important that our camshafts are machined to precise measurements on computer controlled turret lathes. This method ensures both the accurate sizing of journal bearings and the correct concentricity between the cam head and cam shaft. 

Further increasing the quality of these camshafts is the method in which the spline teeth are cut. Many manufactures broach the teeth from the shaft, but this can make for a weaker spline tooth. Our camshafts have their shaft splines are machine rolled for the greatest amount of strength and dimensional integrity. 
To prevent the kind of wear and damage caused by normal use, these S Cams are heat treated for maximum endurance. The critical areas of the camshaft, such as the cam head and the spline teeth are induction hardened to prevent the premature failure due to accelerated wear. 

Quality Camshafts Tested for Excellence 
Finally, to ensure the quality of the camshaft, each stage of the manufacturing process utilizes statistical process control to guarantee excellence at any step in the process, on every part made.
