Series of dynamic locking-rod units for cylinders ISO15552. The
piston-rod brakes series ABK can be supplied normally closed
The peculiarity of this series is to lock the cylinder piston-rod while
moving and to hold it still even in presence of pressure in the
chamber.
A special feature of the series ABK is the absolute absence of axial
movement and rotation of the cylinder piston-rod.
For the application of the piston-rod brake ABK to a cylinder
ISO15552 is necessary to order the cylinder with the rod predis-
posed for this (the extended one in hardened steel, option B1, see
page 1.5.1).
