Product Description

Standards:
Bosch Rexroth standard; main dimensions like piston Ø and piston rod Ø correspond to ISO 3320.

Nominal pressure:              250 bar
Static test pressure:              375 bar Reduced test pressure:       315 bar
The maximum operating pressures must be less than or equal to the applicable nominal pressures and apply to applications with shock-free operation with reference to excess pressure and/or external loads. With extreme loads like e.g. high sequence cycle, mounting elements and threaded piston rod connections must be designed for durability.

Minimum pressure:
Depending on the application, application conditions and technical design, a certain minimum pressure (approx. 10 bar) is required in order to guarantee technically unobjectionable functioning of the hydraulic  cylinder.

Installation position: any

Hydraulic fluid (amending data sheet): Mineral oils DIN 51524 HL, HLP (90220) Oil-in-water emulsion HFA (90223) Water glycol HFC (90223)
Phosphate ester HFDR (90222) Polyol ester HFDU (90222)

Hydraulic fluid temperature range: see page 62 Ambient temperature range: see page 62 Optimum viscosity range: 20 to 100 mm2/s Minimum admissible viscosity: 12 mm2/s Maximum admissible viscosity: 380 mm2/s

Cleanliness class acc. to ISO
Maximum admissible degree of contamination of the hydraulic fluid according to ISO 4406 (c) class 20/18/15.
The cleanliness classes specified for the components
must be adhered to in hydraulic systems. Effective filtration prevents faults and simultaneously increases the life cycle of the components.
For the selection of the filters see wuxihyphen.en.made-in-china.com

Bleeding by default secured against screwing out

Color set-up:
Priming: By default, hydraulic cylinders are primed with a coating (color gentian blue RAL 5010) of min. 40 μm, see page 74.
Other colors upon request.
With cylinders and attachment parts, the following surfaces are not primed:

• All fit diameters to the customer side
• Sealing surfaces for line connection
• Sealing surfaces for flange connection
• Connection surface for valve mounting

• Inductive proximity switches
• Position  measurement system
• Measuring coupling
• Spherical / plain bearing
• Lubricating nipples

Painting: By default, hydraulic cylinders can be ordered in four corrosivity categories in the RAL colors, see page 74. With cylinders and attachment parts, the following surfaces are not painted:

• All fit diameters and connection surfaces to the customer side
• Sealing surfaces for line connection
• Sealing surfaces for flange connection
• Connection surface for valve mounting
• Inductive proximity switches
• Position  measurement system
• Measuring coupling
• Spherical / plain bearing
• Lubricating nipples
