UK carbon brush manufacturer
Unlike suppliers who simply resell stock parts, we manufacture carbon brushes in-house — so if what you need isn’t on the shelf, we can make it. That means:
- Custom brushes made to your exact grade, size and configuration
- No dependency on overseas lead times
- Brush holders manufactured to match, not just supplied
- Full control over quality, from raw material to finished part
This in-house capability is also what makes our identification and replacement service fast — we’re not waiting on a third party to confirm or produce a match.
Carbon brushes for electric motors
We supply carbon brushes for all types of industrial electric motors and rotating equipment, including:
- DC motors and generators
- AC motors and alternators
- Power tools and appliances
- Wind turbines and marine equipment
- Obsolete or legacy motors no longer in production
Choosing the correct brush grade matters more than it might seem — the wrong brush leads to sparking, power loss and eventual motor failure. Our engineers match the brush to your specific motor and application to extend brush life, improve contact, and maintain performance under load.
Carbon brush replacement: when and how
Carbon brushes wear down through normal use, and catching the signs early prevents bigger problems. You should consider carbon brush replacement if you notice:
- Excessive sparking where the brush contacts the commutator
- A noticeable decrease in power from your motor or tool
- Increased noise or vibration
- Complete motor failure
Brush wear can also be accelerated by incorrect installation, the wrong brush size, winding faults, commutator issues, or a brush that isn’t shaped correctly to the arc of the commutator — which is why getting the right match matters as much as replacing on time.
On-site inspection available. Our engineers can visit to assess wear, check fitment, and recommend replacement before failure strikes — part of our end-to-end service, not an extra.
