The CDT1 and CDT4 series of NFPA tie-rod hydraulic cylinders are available with fluorocarbon, NBR, PTFE and wear-resistant polyurethane seals. Rexroth uses a chrome-plated piston rod to extend life and prevent damage. The cylinders also feature a single removable bearing made of ductile iron.

Piston rod diameters range from ½ inch to 5 ½ inches on the CDT1 series and from ⅝ inch to 5 ½ inches on the CDT4 series. The cylinders are designed for applications such as machine tool, automotive, press, plastics, civil engineering, material handling and wood/paper equipment.
