Why Rocker Arm Manufacturing Requires Precision
Contact Surface
Surface geometry and finish affect friction, wear and durability.
Pivot Area
Dimensional accuracy at the pivot area is critical for proper assembly and movement.
Material & Hardness
Material selection and surface hardness must match the application and operating conditions.
