Precision Cam Shaft for High Performance Valves

As the core component of the engine valve train, the cam shaft dominates the valve opening and closing timing and lift control, and has three advantages: precise valve control, stable transmission and wear resistance. Precise valve control relies on CNC grinding processing, with cam profile error ≤0.01mm and phase accuracy controlled within ±5′, ensuring that the valve opening and closing time and stroke accurately match the engine working conditions. Stable transmission benefits from the overall rigidity optimization of the shaft body, using 45CrNiMoV alloy steel for integral forging, radial runout error ≤0.008mm, and combined with the surface contact design of cam and tappet, transmission impact vibration is reduced by 40%. Wear resistance is achieved through surface quenching + nitriding composite treatment, the cam working surface hardness reaches HV900-1100, and the wear amount is reduced by 50% compared with conventional treatment, prolonging the service life.This product is wi…
