Milwaukee Disk Spring
Model Number: 40-50-0805
The Milwaukee 40-50-0805 is a genuine OEM Disk Spring for use in compatible Milwaukee tools. Disk springs — also called Belleville springs or Belleville washers — are conically formed disc-shaped springs that generate a high compressive force over a very short deflection distance. This makes them ideal for applications requiring high load capacity in a compact axial space, such as clutch pre-load assemblies, bearing pre-load systems, torque clutch mechanisms, and fastener locking applications. Individual disk springs can be stacked in series to increase deflection travel, or in parallel to increase load capacity, allowing precise tuning of the spring system for the specific force and deflection requirements of each application. A broken, cracked, or permanently flattened disk spring that can no longer maintain the correct pre-load force requires replacement to restore proper clutch or bearing function.
Using a genuine Milwaukee OEM disk spring ensures the correct outer diameter, inner diameter, cone height, and spring rate for the assembly it pre-loads. Non-OEM disk springs may not match the original load characteristics, leading to improper clutch or bearing performance. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct disk spring for your specific unit.
