Product DescriptionACE81-20x26 Shaft Clamping Element
Available for shaft diameters down to 11mm, these shaft clamping elements are designed to fit into very small diameter hubs, being particularly suited to timing pulley and overload clutch applications. A spacer ring prevents axial movement during clamping; and design ensures good levels of concentricity. For correct operation of these units, the hub diameter should not be less than the flange diameter D2, even though with many materials stress limits would allow selection of smaller hub diameters.
Recommended tolerances for full torque transmission are:-
X = Distance required to remove screws, additional clearance for allen key may be required.
