A tapered adapter bush for a size 24 ROTEX (KTR) elastomeric jaw coupling. It seats in a 28 mm hub bore and gives the shaft a tapered seat running 13.25 mm to 16.75 mm, which is how a taper-shaft motor or pump is clamped into a straight-bored coupling hub without a keyway doing all the work.
This is a single bush, not a coupling and not a complete coupling half. Neither the driving nor the driven ROTEX hub is included. The flexible element, the star-shaped elastomer insert that transmits the torque, is not included. A working drive uses two hubs plus one element in addition to this bush.
A ROTEX is a jaw coupling: two toothed hubs with an elastomer star between them.
It accepts modest misalignment and damps torsional shock.
The metal jaws stay engaged even if the element degrades, so the drive continues to turn.
Size 24 is the small-to-mid ROTEX size.
With the standard 92 Sh A element the size is rated in the region of 35 Nm nominal torque. Element hardness changes that figure.
The taper is the fit-critical dimension.
Type: tapered adapter bush for elastomeric jaw coupling.
Coupling series and size: ROTEX 24.
Outside diameter: 28 mm.
Bore: tapered, 13.25 mm to 16.75 mm.
Coupling family nominal torque: approximately 35 Nm with a standard 92 Sh A element.
One bush. New old stock.
ROTEX hubs and elements are size-specific: a size 24 element does not fit a 28 or a 19, and no other maker’s jaw element is a legitimate substitute for a KTR ROTEX element of a given size. Other bushes in the size 24 range cover different taper and straight bores; those are related sizes, not equivalents to this one.
