Material: Hub aluminium. Bellows stainless steel. Version: Bright. Note: Clamping the hub with a grub screw is a cost-effective alternative to the metal bellows couplings with radial clamping hub (23000). Short mounting times and an easy installation even in difficult to reach places. Take note of the required tightening torque for the grub screw. To ease removal, a flat milled on the shaft is recommended. Temperature range: -20 °C to +90 °C. Assembly: The shaft to hub bore fit should be a transition fit. The play should be min. 0.01 mm and max. 0.04 mm. i.e: shaft Ø 5 k6 bore Ø 5 G7. Bores smaller than D1/D2 min. are possible, however an optimal transfer of the nominal torque is no longer guaranteed. As the metal bellows are made of thin stainless steel plate, special care should be taken during installation and removal. Damages to the bellows can render the coupling unusable. On request: Hub bores D1 and D2 with separate tolerance class or range.
