A Concave Wheel Washer is a precision metal component with a curved or recessed surface designed to work in combination with a Cam Gasket. Together, they create a precise positioning and automatic return mechanism, providing a smooth, controlled “click” or tactile feel during operation. This structure is widely used in rotary adjustment systems, control knobs, and mechanical linkages requiring accurate alignment.
When paired with a Cam Gasket, the Concave Wheel Washer plays a key role in achieving positioning and automatic return. The concave surface interacts with the cam structure to produce stable frictional resistance, enabling smooth rotation, precise positioning, and a self-resetting feel after movement. This combination enhances both functionality and user tactile experience.
The washer is made from high-strength spring steel materials such as 65Mn, SK5, and SK7, which provide superior elasticity, toughness, and resistance to deformation.
Hardness (HRC): 43 – 50
This ensures excellent wear resistance and stable performance over prolonged use.
The Concave Wheel Washer is available in multiple dimensions to meet different application needs:
Inner Diameter (ID): 3.02 – 8.03 mm
Outer Diameter (OD): 5.5 – 10 mm
Thickness: 1.0 – 1.5 mm
These precise specifications ensure compatibility with various cam systems and rotational components.
To enhance durability and resistance to corrosion, the Concave Wheel Washer can undergo multiple surface treatments, including:
Environmental Nickel Plating
Chemical Nickel Plating
Black Oxide Treatment
Zinc-Nickel Alloy Coating
These finishes improve both appearance and performance, ensuring long-lasting stability in demanding mechanical environments.
Make it easy for customers to make shafts and apply them to more fields.
