Heavy duty T4 thruster offers smooth actuation and high static load-carrying capability. A black anodized body, precision re-circulating ball bearings, and four guide shafts double load-carrying capacity and reduce deflection. It is available in 2-, 2 1/2-, and 3-in. bores and in standard stroke lengths of 1- to 12-in. increments. Strokes to 36 in. are available. Air cushions, internal and external bumpers, and magnetic position sensing are optional.
