This sleeve and ball assembly supports smooth mechanical movement by reducing friction and maintaining alignment between connected parts. Designed for precision and durability, it is replaced when wear causes binding, noise, or reduced performance.
This is an authentic Milwaukee replacement part that has been sourced from the original manufacturer to be used with impact drivers, wrenches, and screwdrivers. The steel ball is used to reduce friction between the anvil and the impact assembly. The steel ball is priced as a single item.
This genuine manufacturer-sourced component is made for use with Milwaukee power tools. It is an identical replacement for a missing or a faulty 5mm ball that was installed on a new unit. Please make sure to refer to the appropriate diagrams of your model for the correct location and application of this hardware. Keep in mind this high-quality part is made of durable metal and is sold individually.
