    Two-Piece Rigid Couplings

    Two-piece rigid couplings have the same benefits as one-piece style with the added advantages of being serviced in-place, opposing hardware for a balanced design and step bores with keyways. They are supplied with proprietary Nypatch® anti-vibration coating, which allows for repeated installations, prevents screws from coming loose during operation, and provides the necessary dissimilar material in stainless steel couplings to reduce galling. Straight bore rigid couplings from Ruland are precision honed to ensure bores are collinear. This is important when the rigid coupling is used in a precision servo system as honing allows for greater surface contact with the shaft and higher torque transmission capabilities. Ruland manufactures two-piece rigid couplings in 1215 lead-free steel with a proprietary black oxide finish and 303 stainless steel.
