Made-to-Order Clamping Shaft Couplings
For Keyed Shafts
For Round Shafts
When other one-piece clamping couplings won’t fit your shafts, we’ll machine a shaft coupling with the exact shaft diameters you need. Choose these couplings when your shafts are undersized from wear or oversized from layers of coatings and finishes. Slide them onto the ends of your shafts and tighten the clamping screws for a secure hold that won’t damage your shaft. These couplings are rigid and must be used on aligned shafts. They prevent movement between the shafts, so they can handle high-torque applications.
Couplings for keyed shafts have keyways that firmly grip the shaft’s key to eliminate slipping. They handle higher torque than couplings for round shafts. All keyways have standard ANSI dimensions.
Through-Bore Shaft Couplings—For Keyed Shafts
Through Bore
To Order: For keyed through-bore shaft couplings, please specify your shaft diameter in 0.001” or 0.1 mm increments within the range listed. Also specify the keyway size that matches your shafts.

Made-to-Order Two-Piece Shaft Couplings
For Keyed Shafts
For Round Shafts
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.
