Linear Actuators

The HD-Series and A-Series actuators feature die-cast aluminum powerheads, zinc-plated inner and outer tubes, factory-set torque limiters, and can be specified with 12, 24, or 36 Vdc and 110 or 220 Vac.

Designed to handle moving loads up to 2,500 lb and static loads to 5,000 lb, the HD-Series Acme screw actuators are for use in agricultural, construction, and off-road vehicles, as well as adjustable seat mechanisms, aircontrol and venting equipment, satellite-dish positioners, lift tables, and personal handicap equipment. Stroke lengths range from 4 to 48 in. with three gear ratios: 17:1, 25:1, and 55:1.

For more demanding applications, the A-Series actuators have dynamic load capacities to 3,000 lb and static loads to 5,000 lb. The actuators are designed with either round 2.25-in. or square 2.5-in. tubing and a .75-6 Acme screw. Gear ratios are 34:1 or 110:1 and stroke lengths are 4 to 18 in.
