Milwaukee Copper Spindle Spacer
Model Number: 45-88-8565
The Milwaukee 45-88-8565 is a genuine OEM Copper Spindle Spacer replacement component for compatible Milwaukee power tools — a precision-dimensioned copper spacer that maintains the correct axial positioning and clearance between spindle components, bearing assemblies, or drive train elements within the tool's output mechanism. Spindle spacers control the exact axial position of components on a rotating shaft — they establish the precise gap or preload between bearings, set the correct spacing between gears and drive components, and maintain the dimensional relationship between rotating and stationary parts that the tool's design requires for smooth, accurate, and efficient power transmission. When a spindle spacer wears down from extended service, distorts from overload loading, or is lost during a service operation, the components it spaces lose their correct axial positioning, resulting in bearing preload changes, gear mesh inaccuracies, increased noise and vibration, and potentially premature bearing or gear failure.
The copper material specification for this spacer is not incidental — copper provides specific mechanical properties including thermal conductivity, corrosion resistance in the tool's lubrication environment, and a precise hardness range that allows the spacer to function correctly under the specific load and environmental conditions of this tool application without the galling, seizing, or corrosion that steel or aluminum spacers might experience in the same application. Always verify your specific Milwaukee tool's model number and serial number at milwaukeetool.com or reference the illustrated service parts diagram to confirm the correct copper spindle spacer part number before ordering, as spacer dimensions and specifications are unique to each tool model and shaft position within the drive train.
