BRANT HYDRAULIC -- ISO 6022 cylinders
Features ¡V Standards: DIN 24333, ISO 6022 and VW 39 D 921 ¡V 6 mounting styles ¡V Piston O: 40 to 320 mm ¡V Piston rod O: 25 to 220 mm ¡V Stroke length up to 6 m Standards: The installation dimensions of the cylinders and mounting styles meet the requirements of DIN 24333 and ISO 6022. 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). Installation: Optional Pressure fluid / pressure fluid temperature range: HL, HLP, HFD-R: -20 ¢XC to +80 ¢XC HFA: +5 ¢XC to +55 ¢XC 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. Undercoat: The hydraulic cylinders are, as standard, painted with a max. thickness of 80 £gm. Other color tones on request. Acceptance: 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 £p > 320 mm are available on request. For assembly, commissioning and maintenance cylinders, please take the operating guidelines stated in catalogue into account! |
