Germany Mubea Disc Spring Belleville Spring Washer for CNC machine Spindles Drawbars
This is called disc spring, manufactured by Mubea, Germany. Belleville disc springs, also known as conical washers, have a curved shape that creates a spring-like action. They are used in applications that require heavy loads, such as machine tools, valves, wind turbines, slip clutches, piston return springs, overload clutches, and spring actuated brakes.
This type of disc spring stack installed in the machine spindle used to provide the clamping force that holds the cutting tool. These specialized springs are produced with a machined inner diameter, whose geometry is optimized to provide very tight dimensional tolerances and reduced friction during operation.

Belleville springs look like dished washers with a hole in the middle. They come in a wide variety of sizes. These are the most common type of springs used with drawbars and the easiest to locate. Spindle design engineers use a variety of arrangements to accomplish the spring rate and compression distance needed. Belleville springs can be nested together to make a stiffer spring or they can be opposed to making a longer spring.
Here are some models of Mubea spring washers.
