This hydraulic linear unit was designed so that the full piston surface is available during the return stroke.
This means that it is ideal as a core puller unit. You can now choose a smaller piston diameter than for standard core puller units, whilst still obtaining the same power.

The core puller unit is run through linear roller bearings, which have reduced pressure at the front end position, guaranteeing a longer lifespan.

Version with limit position damping on both sides as standard.
