SKU CH-WJ8T-8150C

A pair of 13 mm carbon motor brushes with springs and wire leads for electric motor repair

  • Exact 13 mm x 9 mm x 6 mm fit for many generic electric motors
  • 18 mm spring maintains steady contact pressure during operation
  • Carbon construction with metal terminals resists wear and conducts current efficiently
  • Ready-to-install pair includes wire leads and springs for quick repair
  • Restores smooth running when worn brushes cause poor motor performance

Replacement Carbon Brushes for Electric Motors

This pair of carbon brushes measures 13mm by 9mm by 6mm and includes wire leads with attached springs. They are designed as direct replacement parts for generic electric motors found in various power tools. The set weighs approximately 4g and features a grey and gold-tone finish.

Low-Friction Contact and Spring Tension

The carbon composition provides consistent electrical contact with the motor commutator while minimising wear during normal operation. Integrated springs maintain steady pressure against the contact surface as the brush material gradually erodes. The spring length is 18mm, ensuring reliable engagement throughout the service interval.

Ready-to-Install Repair Components

Each brush arrives pre-fitted with wire leads and springs, eliminating the need to salvage hardware from worn parts. This allows immediate installation once the motor housing is opened. The pair format covers both brush positions in a standard motor, restoring performance without sourcing separate components.

Questions about this item

How do I install these 13 mm carbon brushes and what step is often missed?

Remove the old brushes, noting the spring orientation, then insert each new 13 mm brush with its 18 mm spring and wire lead secured under the terminal screw. The step most people miss is checking that the spring sits flat against the brush holder so pressure stays even.

When will these brushes need replacement again?

Replace them once the carbon block wears down close to the wire lead or the spring loses tension and no longer holds the 13 mm brush firmly against the commutator.

What limit appears first during continuous motor use?

Heat builds up at the commutator contact face, causing the carbon to wear faster and the spring to soften, which reduces brush pressure and leads to sparking.
