45# High Pressure Double Acting Hydraulic Cylinders, dual-acting hydraulic cylinder

1.Seals:Merkel
2.ISO9001:2000
3.Pressure: 250bar.
4.Material:45#


Nominal pressure: 250bar
Static proof pressure: 375bar
Higher operating pressure on enquire.
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 position: arbitrary
Hydraulic fluid:
Mineral oils DIN 51 524 (HL, HLP)
Phosphate ester (HFD-R)
for seal version \"C\"
-20oC to +50oC
HFA (+5oC to +55oC
Water glycol HFC on enquire
Fluid temperature range: -20oC to +50oC
Viscosity range: 2.8 to 380mm2/s
Cleanliness:
Max. permissible degree of contamination of the hydraulic fluid to NAS 1638 class 10. We therefore recommend as filtration element a filter with a minimum retention rate of 6β10≥75.
Stroke velocity: 0.5m/s(depending on the connection ports)
Bleed screw as standard: secured against unscrewing
Acceptance: Each cylinder is tested to Rexroth standards.
Cylinders outside the above parameters are also available if required.
