Supplier part number:
CDT3MX3-25-12-200F
Name: Rexroth - Bosch Tie Rod Cylinder (Single Rod Cylinder) (CDT3 - MX3) 25mm , Stroke = 200mm Description: The MX3 mounting style for the Rexroth CDT3 tie rod cylinder designates an "Extended tie rod at head" configuration . In this design, the cylinder's tie rods extend beyond the cylinder head on the piston rod side. These extended tie rods act as mounting studs to secure the cylinder to the machine .
While I can confirm details about the series and mounting type from the official documentation, the search results do not contain a complete dimensional drawing for your specific combination of the 25mm piston, 200mm stroke, and MX3 mounting . However, I've compiled the confirmed specifications below.
📊 Confirmed Technical Specifications
The following table outlines the core parameters of the CDT3 series and this specific configuration:
Parameter Specification

📏 Key Dimensional Data for 25mm Piston (MX3)
Based on official Rexroth documentation for the MX3 mounting, here are some of the key dimensions for your cylinder's piston size :
Parameter Value (mm)
Piston Rod Thread (KK) M10 x 1.25
Piston Rod Thread Length (A) 14 mm
Port Thread (EE) G1/4
Tie Rod Nut Torque 5.5 Nm
⚠️ Important Design Considerations
The official Bosch Rexroth documentation notes a few key design limitations for the 25mm piston variant:
Line Connection: With a piston diameter of 25 mm, only line connection "B" is possible .
Mounting Restriction: The MX3 mounting type is not possible with the MX1 (extended tie rod on both sides) mounting .
For a complete dimensional drawing and to verify the exact overall length for a 200mm stroke, consulting the official Bosch Re
