In connection with threaded rods, hollow cylinders can create extremely high forces which are helpful for various repair or assembly applications like removing press-fitted parts, pre-stressing of anchors etc.
In addition, hollow cylinders are used as a power source in puller sets and test rigs.
By the use of long threaded rods and by re-adjusting the nut, longer distances can be pulled.

Hollow cylinders are used as the power component within hydraulic puller sets, for pre-stressing of anchor bolts, removing of axles, shafts, bushings, extracting of tubes, as well as for heavy duty pulling applications.
Double acting cylinders have the advantage over single acting cylinders of being able to retract the piston quickly and are ideal therefore for high-cycle pulling applications.
