Abstract
Clutch and brake components especially adapted for use in electromagnetic semblies (50) includes a first disc (56) or plate having a ground surface (58) comprising parallel surface features and a second disc or plate (64) having a turned surface (66) comprising circular or spiral features. Excellent static and dynamic frictional coefficients are achieved. Preferably, the ground (58) and turned (66) surfaces have roughness of between Ra 3 and 300. A wide variety of variously alloyed steels may be utilized to fabricate the clutch or brake components.
