Nominal pressure: 250 bar
Static proof pressure: 375 bar
Higher operating pressures on request.
The specified operating pressures are only valid for applications with shock-free operation. If extreme loads occur, e.g. as happens in high sequence cycles, the fixings and piston rod thread connections need to be designed for durability (fatigue strength).
Pressure fluid / pressure fluid temperature range:
- HL, HLP, HFD-R: -20 °C to +80 °C
- HFA: +5 °C to +55 °C
- Water glycole HFC on request
Viscosity range: 2.8 to 380 mm2 /s
ISO cleanliness class
Maximum permissible degree of pressure fluid contamination is to ISO 4406 (c) class 20/18/15.
Stroke velocity: Up to 0.5 m/s (depending on the connection ports), higher stroke velocities on request.
Bleed screw as standard:Secured against unscrewing.
The hydraulic cylinders are, as standard, painted with a max. thickness of 80 μm. Other color tones on request.
Each cylinder is tested to Brant standards. Cylinders whose application data lies outside the stated values can be offered as a special version. Cylinders with piston Ø > 320 mm are available on request. For assembly, commissioning and maintenance cylinders, please contact us for more details.
