HOME > YPR Product > Camshaft
Camshaft delivers the motion to valves by changing the movement of crankshaft into the reciprocation of tappet or rocker arm and adjusts valve's opening and shutting. Cam profile should equivalent to the lift of valves and the cam shape is complicated and precise, and so the characteristics of Cam and Shaft requires different material.
