Bearing Kit For Armature (47/49/50) Motor Service Kit

Features

• Armature bearing replacement kit Covers the key bearings supporting the armature in the motor assembly.
• Parts-diagram referenced fitment Replaces reference parts (47, 49, 50) for accurate servicing and rebuild work.
• Maintenance-friendly solution Ideal when stripping the motor to address noise, vibration, or bearing wear.

Benefits

• Helps reduce vibration and noise: Fresh bearings can restore smoother rotation and quieter running.
• Supports motor efficiency: Better alignment and reduced friction can help the motor run cleaner and cooler.
• Protects related components: Replacing worn bearings can reduce stress on the armature, housings and brush system.

Extra Information

• This motor service kit covers the bearing kit for the armature referenced as parts (47, 49 and 50) on the applicable parts diagram.
• Common bearing failure symptoms include rough feel when rotated by hand, abnormal noise, excessive heat, and noticeable shaft play.

Safety

• Disconnect the tool from the power supply before any servicing, stripping, or reassembly work.
• Wear eye, ear and dust protection when removing bearings, cleaning housings, or handling metal components.
• Use proper pullers/press tools for bearing removal and installation—avoid slipping tools and avoid damaging the armature shaft.
• After reassembly, run the tool briefly with no load to confirm smooth operation before returning to heavy drilling.
