Description

Material
Spider polyurethane hardness Shore 98A.
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.
