• Small electric motors in workshop equipment and appliances
• Maintenance and repair tasks where matching brush dimensions are required

Key specifications

• Brush type: carbon (graphite) conductive contact
• Physical dimensions: 5 mm × 8 mm × 16.5 mm
• Intended application: commutator and slip ring contact in electric motors
• Compatibility: designed for small to medium-sized motors and common power tools

How to use

Turn off and disconnect the equipment from the power source before attempting replacement. Access the motor brush holder according to the tool or motor service instructions, remove the worn brush and inspect the holder for debris or excessive wear. Install the GEKO BS905 carbon brush ensuring correct orientation and secure electrical connection; confirm that the brush moves freely in the holder and makes consistent contact with the commutator. Reassemble the housing and test the motor under no-load conditions to verify proper operation before resuming normal use.

Usage recommendations

For optimal performance, replace brushes in pairs when applicable and maintain the commutator surface by cleaning or light dressing if signs of pitting or heavy carbon deposits are present. Use the specified 5×8×16.5 mm size to ensure proper fit and electrical contact; consult the motor or tool documentation if uncertain about compatibility.
