Polyurethane, NBR, PTFE and fluorocarbon among options for sealing systems covering machine tool, automotive, plastics machinery and other applications.
(www.boschrexrothproducts.com/cylinders — Bethlehem, PA) The Bosch Rexroth CDT1 and CDT4 series of NFPA tie-rod hydraulic cylinders come with options for sealing systems including fluorocarbon, NBR, PTFE, and wear-resistant polyurethane seals.
Designed for applications such as machine tool, automotive, press, plastics machinery, civil engineering, material handling and wood / paper equipment, the CDT4 series operates at a nominal pressure rating up to 3,000 psi. The CDT1 nominal rating is 1,500 psi, depending on bore size.
The cylinders feature a single removable extra-long bearing made of ductile iron for longer service life. Reduced guide clearance provides uniform load distribution while a spiral groove in the rod bearing keeps it lubricated and compensates for pressure change.
Rexroth uses a case-hardened chrome-plated piston rod to extend seal life and lower susceptibility to damage. Seal extrusion and tube seal leakage is eliminated by precisely centering the tube to the head end cap.
The piston is mechanically secured to the rod to avoid piston / rod separation. High-tensile steel tie rods with rolled threads add strength and corrosion resistance.
The CDT cylinders contain an ISO 11926-1 SAE straight thread connection port and patented air bleed secured against unscrewing. Piston rod diameters range from ½ inch to 5 ½ inches on the on the CDT1 Series, and from 5/8 inch to 5 ½ inches on the CDT4 Series. Bore diameters range from 1 inch to 8 inches, while stroke lengths are available up to 120 inches.
