Helwig Carbon Products, Inc. has been designing and manufacturing high quality brush holders for over 35 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.
