Product Descriptions

Double acting hollow plunger hydraulic cylinder also called tensioning cylinder, cross-core cylinder  and hollow plunger cylinder, the operation is convenient and the service life is long, widely used in prestressed construction, bridge building, highway and railway construction, power plant power station building, equipment lifting, mechanical disassembling, etc..

The center hole can provide the steel strand, the steel bar and so on through, the center aperture can be processed according to the use unit needs.

Double acting hollow plunger hydraulic cylinder is applied to long distance stroke, at the same time, the hydraulic traction force produced by the piston can be fully utilized in the recovery of the piston operation. Hollow plunger design, which can produce both pushing and pulling force, the design of the double action can be quickly retracted and accurately control the return distance.

Product Features
