FAQ

Question?
How do I determine the stroke length of this specific cylinder?

Answer: The stroke length is encoded in the full type number but is not explicitly listed on the plate. The most accurate way is to measure the distance the rod travels from its fully retracted to its fully extended position.

Question?
What type of hydraulic fluid is recommended for the Rexroth CD70 series?

Answer: CD70 series cylinders are typically compatible with standard hydraulic fluids based on mineral oil (HL, HLP) according to DIN 51524. Always check the machine’s documentation for specific system requirements.

Question?
Can the seals in this used cylinder be replaced?

Answer: Yes, Rexroth provides seal kits for their cylinders. Replacing the seals is a standard refurbishment procedure to restore the cylinder to optimal performance and prevent leaks.
