Tell us the size of each shaft, and we'll machine a custom two-piece coupling to meet your needs. A good fit for uncommonly sized shafts, as well as shafts that are over- or undersized due to thick coatings or wear, these couplings allow you to specify a shaft size for each side of the coupling to the nearest 0.001" or 0.1 mm. A two-piece design means you can install and remove them when access to the shafts is limited by components that are already in place. Clasp the two pieces around the shaft ends and tighten the clamping screws to install; separate the two pieces to remove.

Because these are rigid couplings, the two shafts must be properly aligned. Rigid couplings are good for high-torque applications where there's no relative movement between the two shafts.

Couplings for keyed shafts have keyways that are sized to fit ANSI standard machine keys. Insert a machine key in between the coupling and shaft to lock the coupling in place and transmit high levels of torque without slipping.
