Description

Material
Centre disc polyacetal.
Hub aluminium.
Note
The clamping of the hub by means of a grub screw is a cost-effective alternative for the Oldham-type couplings with radial clamping hub (23030). Short assembly times due to the clamping hub with grub screws.
The couplings can be installed in a fully assembled state, or push-in mounting is also possible. The required tightening torque of the grub screw must be observed. For easy dismantling we recommend machining a flat on the shaft.
Assembly
The shaft to hub hole 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.
Advantages
- robust
- plug-in
- play-free
- short design
On request
Hub bores D1 and D2 with separate tolerance class or range.
