Designed for machine tool, automotive, press, plastics machinery, and other applications, the CDT4 operates at pressures to 3,000 psi. The CDT1 is rated to 1,500 psi. The cylinders feature a removable extra-long, ductile-iron bearing that reportedly gives long service life. Minimal guide clearance uniformly distributes loads while a spiral groove in the rod bearing keeps it lubricated and compensates for pressure changes. A casehardened, chrome-plated piston rod also extends seal life and lowers susceptibility to damage. Precisely centering the tube to the head end cap eliminates seal extrusion and tube-seal leakage. Piston rod diameters on the CDT1 range from 0.5 to 5.5 in., and from 0.62 to 5.5 in. on the CDT4 Series. Bores range from 1 to 8 in. and lengths to 120 in.
