Note
Clamping the hub with a grub screw is a cost-effective alternative to the elastomer dog couplings with radial clamping hub (23022). Short mounting times.
The couplings can be mounted completely assembled or plug-in mounting is also possible. Lightly oil the spider to ease assembly. Take note of the required tightening torque for the grub screw. To ease removal we recommend milling a flat on the shaft.

Assembly
The shaft to hub bore fit is a transition fit. The play should be min. 0.01 mm and max. 0.04 mm i.e.
shaft: Ø 6 f7
hub: Ø 6 H8.
Bores smaller than D1/D2 min. are possible, however an optimal transfer of the couplings nominal torque is no longer guaranteed.

On request
Hub bores D1 and D2 with separate tolerance class or range.
