Features and applications

Particularly suitable for applications such as presses, moulding machines, rolling mills, steelworks hydraulics and plants where there are vibrations, large moving masses, radial loads and impact conditions, where a very robust structure is required to ensure a long service life.
The bronze guide system for both rod and piston delivers excellent performance even when radial loads are present, reduces friction during rod movement and, thanks to its properties, protects the surface from scratches, thus preserving the sealing capacity of the seals and preventing the occurrence of leaks.
The presence of adjustable hardened steel end-of-stroke cushioning ensures correct load deceleration at the end of the stroke, with a long service life.
They can be equipped with proximity sensors to detect the position of the piston at both ends of the stroke.
