Description
Overview:
This Ball Bearing is a genuine Milwaukee replacement part for select 18V impact wrenches, including the M18FHIWF12 and M18ONEFHIWF12. Made from durable, hardened bearing steel with precision-ground raceways, it supports rotating components in the drive train, reducing friction and limiting wear under high torque and repeated impact loads. A correct, like-for-like fit ensures the bearing seats properly in the housing and on the shaft, helping to maintain alignment, smooth rotation, and consistent tool performance. Replacing a worn or noisy bearing helps protect surrounding parts such as gears and the anvil, and can restore efficiency and running smoothness. Ideal for routine servicing or repair, this genuine part helps keep your Milwaukee impact wrench reliable on site and in the workshop.
Key Features:
- Genuine Milwaukee part for assured compatibility and reliability
- Engineered specifically for M18FHIWF12 and M18ONEFHIWF12 platforms
- Hardened bearing steel construction for long service life
- Reduces friction, heat, and wear inside the gearbox and impact mechanism
- Supports high radial loads typical of heavy-duty impact use
- Smooth, precise running to maintain performance and minimise vibration
- Direct replacement with straightforward fitting during routine servicing
- Helps prevent secondary damage to gears, anvil, and other components
- Suitable for both workshop maintenance and on-site repairs
Typical Applications:
Used during maintenance or repairs when an original bearing shows play, roughness, or noise. Suitable for preventative servicing to keep impact wrenches performing reliably in automotive work, construction and installation, plant hire fleets, fabrication, and general mechanical tasks.
