Brush Holders

Helwig Carbon Products, Inc. has been designing and manufacturing high quality brush holders for over 49 years. Our grounding breaking research on the effects of spring pressure relating to brush performance, led to superior brush holder designs using “Constant Force Springs.” Constant force springs can dramatically improve brush life, resulting in lower maintenance costs. Helwig Carbon is unique in offering the carbon brush and holder design and manufacturing in the same facility. This ensures that both the brush and brush holder work collectively to provide you with the best performance, savings and brush life possible.


  • Direct replacement of original OEM holder
  • Replaceable constant force springs
  • Proper spring force for the application
  • Custom made for your equipment
  • Convenient height adjustability
  • Individual, easy to replace components
  • Longer carbon brushes for additional brush life and less

Over 40 of the popular brush holder styles are carried in stock. Helwig Carbon also refurbishes GE magazine brush holders.

Helwig offers replacement spring assemblies or spring repair for virtually every type of constant force brush holder, including turbine ring magazines. Our spring assemblies are designed to meet or exceed the performance of the original part. Over 35 popular spring styles are carried in stock.

Turbine ring holders for GE and Westinghouse are carried in stock ready for immediate delivery. Get your GE magazine holders refurbished at a fraction of the cost of a new brush holder.


An optional wear device is available with selected springs to easily detect brush replacement.

Helwig Quick Disconnect (HQDs) terminals and mounts make changing carbon brushes fast and easy. With no screws to remove or replace, the HQD terminals and mounts snap together in a tight positive locking action. The electrical connection remains secure in the roughest conditions and is manufactured to handle 200 amps continuously. Styles and sizes can be threaded to fit most existing equipment.

Check out our shaft grounding brush holder and brush holder kit, which effectively shunts static and induced shaft currents away from the bearings. The silver graphite brush maintains the lowest contact drop so shaft voltages stay at safe, minimum levels near zero. Also effective in contiminated environments.
