The Bosch Rexroth CDT1 and CDT4 series of tie-rod hydraulic cylinders feature a single removable ductile iron bearing for improved service life. Designed for sealing system applications including machine tool, plastics machinery, and material handling equipment, the CDT4 series operates at a nominal pressure rating up to 3000 psi (207 bar), while the CDT1 offers 1500 psi (103 bar). Reduced guide clearance provides uniform load distribution, and a rod bearing spiral groove lubricates and compensates for pressure change. High-tensile steel tie rods with rolled threads improve strength and corrosion resistance. Piston rods are available in various diameters and stroke lengths.
