Hydraulic Cylinders

Idraulica Sighinolfi Albano is able to design and manufacture hydraulic cylinders from 32mm up to 650mm bores, with length up to 11 metres.
After a first collection of information useful to design the cylinders, we start to draw the cylinder with CAD 3D integrated with FEM Analysis and calculation to achieve third-party certifications (DNV, ABS, GL, LR, BV) and ensure in compliance with every request.

In the last part of the process, there is the assembly and the final check supervision: our staff of engineers and highly specialized experts are at customers’ disposal to guarantee the highest level of quality and reliability in every step of the process.

PISTON ROD PROTECTION extreme and high corrosive environments

We protect the piston rod of our hydraulic cylinders by means of surface treatments and coating which are studied in a very close cooperation with our customers and certified by a research together with universities and suppliers.

The process encompasses different steps:

  • Thermal spray of metallic super alloys HVOF
  • Fusion welding of metallic super alloys PTA
  • Nickel Chromium
  • Hard chrome plating
  • Induction hardening
  • Nitriding
