KJF BDV Block Clamp, Hydraulic, Vertical Push/Pull Type

KJF BDV Block Clamp, Hydraulic, Vertical Push/Pull Type

Double-acting hydraulic block cylinder (vertical type) about 80 mm shorter than a conventional hydraulic cylinder, for pushing or pulling in tight fixture spaces.

Key features

  • Double-acting (push and pull); compact block body easy to install in narrow spaces
  • Bores Ø20-125 mm with various strokes
  • Threaded-rod (C), pin-hole-rod (P) and gasket-port (G, GU, GC, GCU, GP, GPU) versions with the same specifications
  • Special strokes, port locations, rotation prevention and valves available as design changes
  • BDV-20 size may ship with a "K" dimension of 0; check piping before ordering

Specifications
