Material: Housing made of aluminium alloy with iridite NCP finish. Inner hub made of steel. As sliding hub for a driving wheel, for concentric arrangement.
The driving wheel hasto be mounted by the customer
on the outer diameter 21.97mm +0/-0,02mm.

The construction is simple and basically consists of 4 or 6 clutch plates
which are connected to the inner hub and held by the outer housing.
Max. slip-speed 1000 rpm. Torsional backlash of the coupling below 2°.
Torque range with 2 friction plates 2.4 Ncm to 53.8 Ncm.
Torque range with 6 friction plates 7.8 Ncm to 132.4 Ncm.
Maximum operating temperature 80°C.
An adjusting ring - screwed to the outer body - serves to adjust the torque.
Two sintered bearing sleeves serve as bearing housing to inner component.
An O-ring seals the hub off against dirt.
