Slotted Disc Spring – High Deflection and Progressive Rate
About the Product
A Slotted Disc Spring is a modified Belleville washer featuring radial slots cut into the conical body. This modification dramatically changes the spring's load-deflection curve, providing a much softer and more progressive spring rate than a standard solid disc spring of the same dimensions. The slots allow the material to flex and distribute the load more evenly, resulting in higher deflection capabilities before reaching the flat position.
- Significantly reduced spring rate for softer force application.
- High deflection capacity for applications with greater movement.
- Improved uniformity of load distribution via multiple radial slots.
- Excellent suitability for dynamic, high-cycle applications (e.g., clutches, valves).
Slotted Disc Springs are engineered for precision machinery where standard disc springs are too stiff, but the space constraints require a conical design. They are essential in clutches, safety relief valves, and coupling systems where their unique characteristic curve (lower force, higher stroke) provides optimal performance and fatigue resistance. These are custom-made to meet specific load and space requirements.
