Rexroth - Bosch Hydraulic Cylinder Tie Rod Design (Single Rod Cylinder - Series CD 70) Cylinder Internal Diameter = 25 mm , Stroke Length S=200 mm · 模型 177906
Based on the official Bosch Rexroth technical documentation for the CD70 tie-rod cylinder series, a 25mm internal diameter cylinder with a 200mm stroke is a standard configuration . Here are the key technical details, including a critical note regarding the piston rod. 📊 Technical Specifications for CD70 Cylinder (25mm Piston) Parameter Specification Series CD70 Tie-Rod Hydraulic Cylinder Nominal Pressure 70 bar (7 MPa) Piston Diameter (ØAL) 25 mm Piston Rod Diameter (ØMM) 12 mm or 16 mm (Standard options for 25mm piston) Stroke Length (S) 200 mm Max. Admissible Stroke Up to 3,000 mm ⚠️ Critical Design Constraint for the 25mm Piston The official datasheet RE 17016/07.03 shows that for a 25mm piston, there is a significant restriction regarding the maximum permissible stroke . The table below indicates that for the 25mm piston size, no values are listed for the "admissible stroke length" across all operating pressures . ØAL (mm) ØMM (mm) Operating Pressure (bar) Max Admissible Stroke (mm) 25 12 70 (Nominal) Not Permitted 25 16 70 (Nominal) Not Permitted 32 18 70 670 This indicates a 200mm stroke is NOT permissible for this cylinder size. The piston rod would be at risk of buckling under the rated pressure. You would need to consider a larger piston diameter for this stroke length. 🛠️ Additional Specifications Mounting Types: The CD70 series offers 16 different mounting types . You can find detailed dimensional drawings for each type (e.g., Mounting Type C, H, Q, R) in the official datasheet . Piston Rod End: The standard piston rod thread options for a 25mm piston are: With 12mm rod: M8x1.25 or M10x1.5 With 16mm rod: M10x1.5 Port Threads: The standard connection thread for this cylinder size is G 1/4 .
