A Cam Gasket is a precision-engineered washer designed to work together with a concave wheel gasket to achieve accurate positioning and a smooth automatic reset feel. It is commonly used in mechanisms requiring controlled rotation and tactile feedback, such as adjustment knobs, control levers, or rotary assemblie
The main function of the Cam Gasket is to provide positioning and automatic return through its precise shape and frictional contact with the concave wheel gasket. This combination ensures stable movement, consistent torque, and a reliable “click” or return feel during operation, improving both performance and user experience.
The Cam Gasket is made from high-quality spring steels such as 65Mn, SK5, and SK7, offering excellent elasticity and durability.
Hardness (HRC): 43 – 50
This range ensures the gasket maintains stable friction performance and long service life under repeated mechanical stress.
The Cam Gasket is available in the following size range:
Inner Diameter (ID): 2.5 – 11 mm
Outer Diameter (OD): 4.5 – 16 mm
Thickness: 1.2 – 2.0 mm
These options allow compatibility with various shaft and cam configurations for different industrial applications.
To ensure corrosion resistance and stable performance, the Cam Gasket can be finished with multiple surface treatments, including:
Environmental Nickel Plating
Chemical Nickel Plating
Black Oxide
Zinc-Nickel Alloy Coating
These finishes provide enhanced wear resistance, aesthetic appeal, and long-term durability even under harsh working conditions.
Make it easy for customers to make shafts and apply them to more fields.
