Nitpicker Actuators provide independently-controlled combined indexing (unidirectional rotation in fixed steps to hard stops) rotation with linear motion. These actuators also prevent backward rotation and feature no accumulating error. All Rotomation nitpicker actuators feature black-anodized aluminum bodies, stressproof steel rod, ball bearings, and stainless steel hardware.
Common Options: two rod types, two rotation directions, 1 or 2" long stop tube on linear section, bumper on reset stroke, integrated flow control or cushion needle valve, magnetic switches for actuator state (end of reset or end of drive stroke on rotary; fully extended or fully retracted on linear) feedback, high-temperature and/or oil-service seals, mount plates, extended pawl shaft for alternate state feedback (use with flag and proximity sensor), 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.
Standard rod strokes: from 0.50" to 12.00", in 0.25" increments.
Tie rod construction offers maximum configurability and durability, and are fully rebuildable. Single rack actuators are designed for general applications where reliability and durability are important. Dual rack actuators have the additional advantages of double torque and zero lash at the ends of the rotation without increasing the footprint of the actuator
