Rexroth - Bosch Hydraulic Cylinder Tie Rod Design (Single Rod Cylinder - Series CD 120E) Cylinder Internal Diameter = 25 mm , Stroke Length S=200 mm · 模型 126886
A Rexroth hydraulic cylinder with the exact model number CD 120E was not found in the available information. However, the search results do provide detailed technical data for the very similar CD70 series, which is a tie-rod hydraulic cylinder . The "E" in the model name likely denotes a specific mounting style, as demonstrated by other variants like CD70F and CD70P . 📊 Technical Specifications for the CD70 Series The following table outlines the key specifications for the CD70 series, which match the piston diameter and stroke you are interested in. Parameter Specification Series CD70 (Tie-Rod Design) Nominal Pressure 70 bar (7 MPa) Piston Diameter (ØAL) 25 mm Stroke Length (X*) Up to 3000 mm (your 200mm is feasible) Max. Admissible Stroke The official datasheet indicates that for a 25mm piston with a 12mm or 16mm rod, no stroke length is permissible under standard operating pressures . This likely means the 200mm stroke is not permissible for this bore size without a larger piston rod. ⚠️ Critical Design Constraint The official Rexroth datasheet (RE 17016) contains a table of "Admissible stroke lengths" which shows that for a 25 mm piston (with either a 12mm or 16mm rod), no stroke length is permissible at operating pressures from 40 to 105 bar . This is a critical safety consideration to prevent piston rod buckling. A 32 mm piston with an 18mm rod is the smallest configuration that supports a 200mm stroke (up to 670mm is admissible at 70 bar) . 🔍 How to Find the Exact "CD 120E" To find the exact details for the CD 120E model: Verify the Model Number: The "120" may be a different series identifier. The "E" likely designates a specific mounting style, similar to how "P" denotes a clevis mount in the CD70P model . Consult Official Documentation: The definitive source for this series is the official Bosch Rexroth datasheet RE 17016. A direct review of this document will provide a complete list of available mounting styles and their dimensional drawings for a 25mm bore. Contact Rexroth Support: For confirmation on a potentially custom or older model variant, contacting Bosch Rexroth technical support is recommended.
