Petrone Oleodinamica is an Italian manufacturer of hydraulic components, part of the ecosystem of specialist European hydraulics firms whose products are found in industrial machinery long after the brand has stopped being familiar to the people maintaining it.
What the brand is known for
- Hydraulic cylinders for industrial and mobile applications, including custom designs.
- Hydraulic power units and manifolds built to application requirements.
- Valve blocks and control assemblies integrating standard cartridges into purpose-built manifolds.
- Special cylinders for presses, marine and heavy-duty service.
Why sourcing these parts is different
Specialist hydraulic manufacturers build to order, which has two consequences. First, the part number often encodes a configuration unique to one machine, so a generic equivalent does not exist. Second, when the original specification is lost, the only reliable route back is the drawing, the nameplate and the dimensions of the failed unit.
How to source a Petrone component
- Photograph the nameplate in good light — bore, stroke, pressure rating and mounting style are usually marked.
- Measure the mounting — pin diameter, eye or flange dimensions, port sizes and centres.
- Record the machine — make, model and the function the cylinder performs.
- Note the operating conditions — pressure, temperature, duty cycle and the hydraulic fluid used.
- Accept that a remake may be the answer — for low-volume specials, manufacturing to drawing is often faster than hunting for remaining stock.
Repair as an alternative
For cylinders, re-sealing or re-chroming a scored rod is frequently cheaper and quicker than replacement. Inspect the barrel bore for scoring and the rod for chrome damage before deciding — a repairable cylinder should not be scrapped, and an unrepairable one should not be re-sealed.
