Two-Piece Rigid Couplings


Two-piece rigid couplings provide the same advantages as rigid couplings made of one piece, but with the additional benefits of repair-in-place as well as opposing hardware for an even design, and keyways that are stepped into the bore. They are equipped with a unique anti-vibration coating that allows for consistent installation, which prevents screws from becoming loose in operation, and offer the required dissimilarity between stainless steel joints that reduce wear. Straight-bore rigid couplings have been precisely ground to ensure they are properly aligned. This is crucial when using rigid couplings in servo systems that are precision designed because honing provides more interaction with shafts as well as greater capability of transmission of torque. We build our two-piece, rigid couplings out of 1215 lead-free and stainless steel 303, with a special Black Oxide finish.
