This genuine Milwaukee ball bearing (OEM No. 4931436062) is a factory-spec replacement for selected M18 cordless impact wrenches, including the M18BIW12 and M18BIW38.

Designed specifically for Milwaukee impact wrenches, it offers a straightforward fit and reliable service life for both tradespeople and DIY users who need tools to run consistently under demanding conditions.
