Hydraulic cylinder mass-produced in accordance with the relevant standards. These are the
- nominal pressures as per ISO 3322,
- diameter of cylinder bores and piston rods as per DIN ISO 3320,
- surface ratios between cylinder bore and piston rod as per DIN ISO 7181.
In addition, DIN ISO 4313 sets out a preferred range for piston strokes, although compliance with these is not always possible.
