The basis of the intensifying hydraulic spindle is that it works with a closed oil cylinder. On inserting the piston into the chamber, the pressure due to the section differences or diameters intensifies with little effort. The movement is light; this is noted on turning the handle which is also smooth. As these are hollow spindles, the force is transmitted inside the threaded spindle. Therefore this carries out only the stroke movement, and enjoys long-lasting wear as it does not have to carry out any clamping force.
