2 2/44 Bosch Rexroth AG Industrial Hydraulics CDH2 / CGH2 RE 17334/02.05 Technical data (for applications outside these parameters, please consult us!) Standards: The installation dimensions of the cylinders and mounting styles meet the requirements of DIN and ISO 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 C to +80 C HFA: +5 C to +55 C Water glycole HFC on request Viscosity range: 2.8 to 380 mm 2 /s Diameter, weights 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 (colour tone gentian blue R 5010) with a max. thickness of 80 µm. Other colour tones on request. Acceptance: Each cylinder is tested to Bosch Rexroth standards. Cylinders whose application data lies outside the stated values can be offered as a special version. Cylinders with piston > 320 mm are available on request as an ABS (Application Based Standardisation) cylinder. For assembly, commissioning and maintenance cylinders, please take the operating guidelines stated in RD 07-B into account!

4 4/44 Bosch Rexroth AG Industrial Hydraulics CDH2 / CGH2 RE 17334/02.05 Engineering software IHC-Designer The IHC-Designer (Interactive Hydraulics Cylinder Designer) is an engineering and selection aid for hydraulic cylinders. With the aid of the IHC-Designer it is possible for designers of machines and systems, by the logically guded type code questionnaire, to quickly and reliable find the optimum hydraulic cylinder solution. The software enables the design and engineering tasks to be carried out quicker and Mounting style overview CDH2 MP3 See pages 6, 7 efficiently. After being guided through the product selection, the user quickly obtains reliable and exact technical data of the selected components as well as the associated 2D and 3D- CAD data in the correct file format for all current CAD systems. You, as a user thereby reduce your costs and therefore increase your competitiveness.

22 22/44 Bosch Rexroth AG Industrial Hydraulics CDH2 / CGH2 RE 17334/02.05 Position measuring system The contactless, absolute position measuring system is rated up to 500 bar. Its function principle is based on the magnetostrictive effect. In connection with this, a torsion impulse is triggered off when two magnetic fields meet. This impulse is directed from the point of measurement via the wave guide inside the measuring scale to the sensor head. The transmission time is constant and virtually independent of temperature. It is proportional to the position of the magnet and can therefore be used as a reference for the actual position value and is converted into a direct analogue of digital output in the sensor head.

26 A/F19 26/44 Bosch Rexroth AG Industrial Hydraulics CDH2 / CGH2 RE 17334/02.05 Proximity switch Inductive proximity switches are used as a reliable end position control for hydraulic cylinders. They are an important element, in providing safety systems, interlocks and/or other machine functions where signals safely and exactly monitor the end position. The up to 500 bar rated high pressure proximity switches operate without contact and contacts and are, there- fore wear-free. Due to safety reasons the proximity switch is protected against being screwed in too deep. The switching distance can, therefore not be adjusted. For the version with proximity switches (Option 1 E ), the cylinders are fitted with proximity switches on each end. Technical data (for applications outside these parameters, please consult us!)
