Milwaukee Disc Spring
Model Number: 40-50-0029
The Milwaukee 40-50-0029 is a genuine OEM Disc Spring for use in compatible Milwaukee tools. A disc spring — also known as a Belleville washer — is a conical washer-shaped spring that deflects axially under load, providing a high spring force in a very compact axial space. Disc springs are used in Milwaukee tools at spindle preload interfaces, clutch mechanisms, and impact systems where a precise axial spring force must be maintained in a very tight space that a coil spring cannot fit. The disc spring must maintain its designed spring rate and free height throughout the tool's service life for consistent mechanism performance. A fatigued, cracked, or flattened disc spring that has lost its spring force requires replacement to restore correct axial preload or mechanism force.
Using a genuine Milwaukee OEM disc spring ensures the correct inner diameter, outer diameter, thickness, and spring rate for the mechanism it serves. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct spring for your specific unit.
