This line of aluminum cylinders features lifting capacities of 20 to 150 tons and stroke lengths to 10 inches. Included in the line are the single-acting RAC Series, double-acting RAR Series, RACL Series single-acting lock-nut, and RAXH Series single-acting hollow. Composite bearings on all moving surfaces prevent metal-to-metal contact. Removable hardened saddles and steel base plates protect plungers and cylinder bases from surface contact.
