Made-to-Order Clamping Shaft Couplings
For Keyed Shafts
For Round Shafts
When you need a strong hold and even grip on shafts that are oversized due to finishes, undersized from wear, or uncommonly sized, we’ll make a coupling for you that fits just right. Tell us your shaft diameters to the nearest 0.001” or 0.1 mm.
These couplings clamp around your shafts to prevent marring them. But, you need access to the end of each shaft to slide them into place. Because they’re rigid, they don’t allow movement between shafts, making them good for high-torque jobs. This also means your shafts must align to connect.
Through-bore couplings connect same-size shafts. Step-down couplings connect different-size shafts.
Couplings for keyed shafts have keyways that are sized to fit ANSI standard machine keys. Insert a key between the coupling and shaft to lock the coupling in place and transmit high levels of torque without slipping.
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
For hard-to-access shafts that are oversized from coatings or undersized from wear, we’ll get you a coupling in the right size that clamps on as two pieces, so you don’t need to move your shafts or installed components. Let us know your shaft diameter to the nearest 0.001” or 0.1 mm. These couplings are rigid, making them good for high-torque applications. However, your shafts must be aligned.
Through-bore couplings connect same-size shafts. Step-down couplings connect different-size shafts.
Couplings for keyed shafts have keyways that are sized to fit ANSI standard machine keys. Insert a key between the coupling and shaft to lock the coupling in place and transmit high levels of torque without slipping.
