This jaw type half-coupling can be used to connect a 12mm shaft to another shaft. It is held in place by two set screws and accomodates a 4mm keyway for a more secure grip. It fits together with another CL8-25 series jaw coupling of any shaft size with a hard elastomer spider in between.

Jaw type couplings are ideal for high-torque applications and applications where shafts of two different sizes need to be coupled. This series of couplers are rated for torques as high as 60 kg·cm and speeds of up to 16000 rpm.

If you're having trouble with slipping, you can file a groove into the shaft where the set screws hold it in place. You can also use a Loctite adhesive on the set screws to ensure that they remain in place.

Assembly

This jaw type half-coupling connects to any other half-coupling in the CL8-25 series with a coupling spider pressed in between. The other half and the spider are both sold separately. See the "Compatible Products" tab for a complete list.

Jaw Couplings

FUNCTIONAL

Jaw couplings are designed to connect to other jaws in the same series, which gives you the option of coupling two differently sized shafts together. Between the two jaw couplings, a coupling spider is used to hold them in place while still allowing for a small amount of flex. The jaw couplings and spiders in the list below will fit together with this coupling:
