Jaw Coupling Half 0.5" Series 24

ID: TRM4319_0
Recommended for new designs: Phidgets Inc. is not the original manufacturer for this product, but we intend to sell it (or a similar replacement with a compatible form, fit and function) for as long as it is available from the supplier.

This aluminium jaw coupling fits a 0.5" shaft and connects to another half coupling with a spider.

This jaw type half-coupling can be used to connect a 0.5" shaft to another shaft. It is held in place by two set screws, and fits together with another series 24 jaw coupling of any shaft size with a hard elastomer spider in between. See the Connection & Compatibility tab for a complete list of compatible couplings and spiders.

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 610 kg·cm and speeds of up to 4000 rpm.


This jaw type half-coupling connects to any other series 24 half-coupling with a coupling spider pressed in between. The other half and the spider are both sold separately.


Jaw Coupling Spider

You'll need a coupling spider to connect this jaw coupling to another. You can find a list of compatible spiders below:

Jaw Couplings


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 in the list below will fit together with this coupling:
