GE19 Curved Jaw Coupling Full Hub Pilot Bore, 19 to 24 mm Bore
Available
Full Hub hubs for curved jaw couplings, with a pilot bore, in sizes GE19 to GE90. Hub type 1a is the full hub. Curved jaw couplings join two shafts with a hub on each shaft and a flexible element between the curved jaws. The element absorbs shock and vibration, and takes up a small amount of misalignment between the shafts. Elements come in two hardnesses, 92 Shore A (yellow) and 98 Shore A (red), and the red element is rated for more torque in every size.
Each hub has a pilot bore, so you can have it bored and keywayed to suit your shaft within the bore range listed for the size. The elements are sold separately.

Selecting and fitting
Choose the size from the torque you need to transmit and the shaft sizes. Use the rated torque for the element you want: the yellow 92 Shore A element or the red 98 Shore A element. Apply a service factor for the type of machine before you check the rating. Each coupling needs two hubs and one element, and the element is sold as Curved Jaw Coupling Red/Yellow Shore Element.
This listing is the full hub. The stepped hub version is Curved Jaw Coupling Stepped Half, Pilot Bore. Taper lock versions of the hubs are also available: see Curved Jaw Coupling Flange Taperlock Half and Curved Jaw Coupling Hub Taperlock Half.
Bore the hub concentric with its outside diameter and keep within the maximum bore for the size. Align the two shafts as closely as you can before fitting the coupling, and check the alignment again once the coupling is fitted. Good alignment gives the longest life, whatever the coupling type.
Dimensions are as listed in the manufacturer catalogue and are for reference. Contact AIMS to confirm a measurement if it is critical to your application.
