Locked Series - Pneumatic Safety Clamping Products - ACE - #19

The chamber between the two ring-shaped spring steel membranes is filled with compressed air and the inside ring is thereby elastically expanded. Due to the resulting shape and the fact that the membranes are radially slotted outwardly at the inner diameter, the clamping can spring back to its original (released)

position.

The enlargement of the diameters frees the shaft, and movement without resistance is possible. The

increased diameter results from the tolerance

between shaft and the LOCKED-R element.

The air pressure in the chamber between both ring-

shaped diaphragms is released. The diaphragms'

return force presses the clamping surface back into contact with the shaft. The spring-brake actuator affects the clamping and needs no additional energy.
