Description
Material
Spider polyurethane hardness Shore 98A.
Hub aluminium.
Hub aluminium.
Version
Bright.
Note
Radial clamping of the hub for short mounting times. The couplings can be mounted completely assembled or a plug-in assembly is also possible. Lightly oil the spider to ease assembly. Take note of the require tightening torque for the clamping screw.
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 28 k6
hub: Ø 28 F6
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.
