Description
Overview:
The Carbon Brush CB-51 is a genuine Makita replacement designed to keep brushed motors in Makita power tools running smoothly and efficiently. Made from a high-grade carbon/graphite compound with an attached lead and terminal, it transfers current to the armature while balancing wear and commutator protection. This OEM component (MPN/OEM No. 194963-1) restores performance when original brushes become short, chipped, or heavily arced. Suitable for professional and home users, it is commonly fitted to a wide range of Makita tools, including models such as 1901 and 1923B. Replacing worn brushes helps maintain consistent power, reduces sparking, and extends motor life, making the CB-51 a cost-effective item of preventative maintenance for site, workshop, and garden machinery tools that see regular use.
Key Features:
- Genuine Makita part for assured fit and compatibility (CB-51, OEM/MPN 194963-1)
- High-quality carbon/graphite for reliable current transfer and controlled wear
- Helps reduce arcing, overheating, and intermittent power loss in brushed motors
- Consistent spring tension for stable contact with the commutator
- Durable construction suitable for frequent or demanding tool use
- Straightforward replacement via brush caps on most compatible models
- Supports efficient motor performance and can reduce downtime and repair costs
- Best practice is to replace brushes as a pair and check commutator condition at the same time
Typical Applications:
Used during routine servicing or repair of Makita power tools to restore performance and reliability. Ideal when tools show reduced power, visible sparking at the brushes, or inconsistent operation. Suitable for site work, workshop maintenance, and DIY use on planers, jigsaws, drills, grinders, and similar equipment that relies on brushed motors.
