Indexing Actuators


Motion symbol used for single-rack indexing actuators and dual-rack indexing actuators.

Indexing Actuators provide unidirectional rotation in fixed precise steps to hard stops. Indexers also prevent backward rotation and feature no accumulating error. All Rotomation indexing actuators feature black-anodized aluminum bodies, precision-ground carbon steel shafts, ball bearings, and stainless steel hardware.

Common Options: preloaded shaft notch, various shafts types, two rotation directions, bumper on reset stroke, integrated flow control or cushion valve, magnetic switches for actuator state feedback, high-temperature and/or oil-service seals, mount plates, extended pawl shaft for alternate state feedback (use with flag and proximity sensor), accurate keyway reference point location, and various port locations.

Standard rotation angles: 12° (30 steps/rev.), 15° (24 steps/rev.), 18° (20 steps/rev.), 22.5° (16 steps/rev.), 30° (12 steps/rev.), 36° (10 steps/rev.), 45° (8 steps/rev.), 60° (6 steps/rev.), 72° (5 steps/rev.), 90° (4 steps/rev.), 120° (3 steps/rev.), 180° (2 steps/rev.), and 360° (1 step/rev.). Combination of angles also possible as long as they add up to 360 degrees total.

Dual Rack Indexing Actuators

Dual rack actuators have the same features and benefits of their single rack counterparts, with the additional advantage of double the torque output for any given input pressure, without increasing the footprint of the actuator.

Delivering engineered solutions since 1967.
Rotomation is dedicated to providing reliable, extremely configurable, and fully rebuildable pneumatic actuators for automation. Custom and special actuators are our specialty.
