Milwaukee 40-50-5262 Pressure Spring

**Milwaukee parts change not only by model# but also by serial number. Milwaukee’s site lets youlook up your tool’s parts diagram.Milwaukee Pressure SpringModel Number: 40-50-5262The Milwaukee 40-50-5262 is a genuine OEM Pressure Spring for use in compatible Milwaukee tools. Pressure springs are helical coil springs that apply a sustained compressive force against a component maintaining consistent contact pressure, pre-load force, or engagement force within a mechanism under static or dynamic conditions. They are commonly used in ball detent systems, clutch engagement mechanisms, chuck jaw return assemblies, and bearing pre-load applications where a controlled, consistent axial or radial pressure must be maintained against the loaded component. Each pressure spring is wound to a specific wire diameter, coil geometry, and spring rate that determines its force output at the operating compression. A broken, set, or weakened pressure spring that can no longer maintain the correct operating pressure requires replacement to restore proper mechanism function.Using a genuine Milwaukee OEM pressure spring ensures the correct wire diameter, free length, and spring rate for the mechanism it serves. Non-OEM springs may not match the original force characteristics, leading to improper mechanism engagement or premature fatigue failure. Always verify your catalog number and serial number on Milwaukee’s website before ordering to confirm this is the correct pressure spring for your specific unit.FeaturesGenuine Milwaukee OEM pressure spring for compatible Milwaukee toolsApplies sustained compressive force to maintain engagement, pre-load, or contact pressureUsed in detent systems, clutch mechanisms, and chuck jaw return assembliesWound to specific wire diameter and spring rate for correct force at operating compressionVerify catalog number and serial number on Milwaukee’s website before orderingSpecificationsType: Pressure SpringMaterial: Spring SteelApplication: Sustained Contact Pressure and Engagement Force in Tool MechanismsCompatibility: Always verify part compatibility using your tool’s model and serial number before orderingIncludes(1) Milwaukee 40-50-5262 Pressure Spring*** This spring is for specific Milwaukee Rotary Hammers.
