AirCraft Air Impact Wrench Service Kit – Bearings (15 & 22) for AT0004 (AT0004-SK03)
At a Glance: Bearing replacement kit for the AirCraft AT0004, supplying the two key bearings (reference 15 and 22) that support smooth, stable rotation.
Bearings are the silent workhorses inside an impact wrench. When they start to wear, you’ll often notice extra noise, vibration, rough running or a tool that just doesn’t feel as smooth under load. The AirCraft AT0004-SK03 bearing service kit replaces the two specified bearings (parts 15 and 22) to restore proper support and alignment for rotating components inside the AT0004. Fresh bearings help reduce friction, improve efficiency and protect shafts and housings from damage caused by wobble or grinding wear.
Worn bearings increase drag and heat, and they can allow shafts to run out of true. Replacing them helps the motor and drive components spin cleanly, reducing internal stress and helping your impact wrench deliver consistent performance.
