LOCKED R

Strong holding force on the shaft

Pneumatic Rotational Clamping
Holding torques 42 Nm to 4,680 Nm

Direct clamping on the shaft: Rotation motions are prevented by the ACE models LOCKED R. Their clamping elements are available for shaft diameters of 50 to 340 mm and ensure maximum holding forces.

The clamp is immediately applied by the diaphragm and spring-plate system when pressure is lost. Pneumatic quick-switch valves reduce the reaction times. The costs are low in comparison with hydraulic clamping systems. Their performance is, however, achieved or exceeded despite the compact and easy to assemble design. Special versions for YRT bearings as well as active clamping elements are additionally available. ACE recommends the use of the optional shaft flange as wear protection. The clamping force can be increased considerably by the use of the additional air function.

Models from the LOCKED R product family are used in mechanical engineering and customised machine tools.
