The constant force springs from Popular Carbon Brush Mfg. Co. are designed for carbon brush holder application. They are used to hold carbon brush to make electrical connection steady to rotor of slip ring, and to commutator of brush motor. They make sure that the carbon brush works consistently by dependably exerting constant pressure to increase brush life and reduce electrical wear. Constant force springs benefit to users through exerting constant pressure for commutator and slipping ring in any brush length.
Our constant force springs provide:
Smooth, even, uniform load through entire length or travel (deflection)
Strong force yield within small spaces
Extensive linear range
