Supplier part number:
CDH3MP5-80-56-300A
Name: Mill Type Cylinder (BOSCH , Rexroth) - Single Rod Cylinder(CD) - Range H3. - CDH3 MP5. - Bore Diameter D=80 mm. - With Stroke Length S=300 mm. Description: Based on the official Rexroth technical documentation, here are the key specifications for the CDH3 MP5 mill-type cylinder with an 80 mm bore and 300 mm stroke.
The CDH3 series is a robust, single-rod mill-type cylinder designed for a nominal pressure of 350 bar (35 MPa) . The MP5 mounting style specifies a self-aligning clevis at the cylinder base .
📊 Technical Specifications for 80mm Bore
For an 80 mm piston diameter, the standard piston rod diameter is 56 mm .
