Pick an actuator size, any size

Pick an actuator size, any size

Tol-O-Matic has introduced line of rod screw actuators that is noteworthy for the breadth of standard sizes available, including metric, English, and ISO sizing, says Derek Wise, project engineer. Six different body sizes are available, ranging from 3/4 to 4 inches and five different lead screw diameters, from 3/8 to 1/2 inch with a solid or ball nut configuration. Any stroke length is available up to an actuator's maximum capacity, with thrust capabilities ranging from 70 to 4,200 lbs.

"With other lines that are more limited, the engineer often has to compromise on the stroke size. For example, he or she may want a 13-inch-stroke but have to settle for a 16-inch-stroke," says Wise. "Obviously, they will be paying for capabilities they don't need, and they'll have to oversize their design."

The actuator features an extruded body, allowing for easy four-sided mounting and an internal guide bearing design that provides rigid support of the thrust rod at the full stroke length and maximum surface area for extended life. "We've got a lot of interest going on in the medical industry today," says Wise. "That's primarily because of the accuracy of the product."
