3" x 8" x 1.25" HYD REPHASING CYLINDER New. LION HYDRAULICS 30WP08-125 ORB 90, welded, double acting, rephasing hydraulic cylinder. Rephasing cylinders for series applications where multiple cylinders extend and retract equally. Two or more cylinders are plumbed in series, with bore and rod diameters sized so all rods extend or retract in unison. The rephase bypass allows oil to bypass piston on full cylinder extension to fill the next cylinder during initial synchronization or to compensate for internal leakage. Non-removable restrictor orifice in retract port.
