Carbon brush set GEKO BS138 5×10×16.5 mm for power tools (G00489)

Carbon brush set GEKO BS138 5×10×16.5 mm is a replacement set of graphite-metal brushes intended for maintenance and repair of compatible power tools and small electric motors. The set is designed to restore electrical contact between stationary brush holders and rotating commutators, enabling reliable current transfer in brushed motors used in drills, grinders and similar equipment. Supplied as a ready-to-install pair (or set), these carbon brushes match the specified dimensions for a direct fit in applications that accept 5×10×16.5 mm brushes.

Advantages

These GEKO carbon brushes combine conductive graphite material with metallic components to provide stable electrical contact and low wear under normal operating conditions. The precisely machined dimensions ensure good mechanical fit and consistent pressure against the commutator, reducing sparking and maintaining motor efficiency. The set simplifies routine maintenance by providing the necessary replacement parts for timely brush exchange.

Suitable for (tasks / use cases)

• Replacement of worn brushes in hand-held drills and angle grinders with compatible brush holder dimensions.
• Repair and refurbishment of brushed electric motors in workshop equipment.
• Preventive maintenance to restore motor performance and reduce noise or sparking.
• Use in hobbyist and professional tool upkeep where 5×10×16.5 mm brushes are specified.

Key specifications

• Brush material: graphite with metal contact element.
• Nominal dimensions: 5 × 10 × 16.5 mm (width × thickness × length).
• Type: replacement carbon/graphite brushes for brushed motors.
• Pack: set supplied for matching both brush positions when applicable.

How to use

Ensure the tool is disconnected from power before attempting replacement. Access the brush holders according to the tool manufacturer's instructions, remove the old worn brushes and note their orientation and spring/holder configuration. Fit the GEKO BS138 brushes in the same orientation, ensuring the contact surface seats properly against the commutator and that springs or retention clips are reinstalled to provide correct pressure. After reassembly, run the tool at no load briefly to confirm smooth operation and to seat the brushes fully.

Usage recommendations

Inspect commutator surface for heavy scoring or debris before fitting new brushes; clean or dress the commutator if necessary. Replace brushes as pairs when both sides show wear. Observe manufacturer guidelines for break-in and avoid prolonged heavy load immediately after installation to allow proper seating.
