Linear Actuators

The Bug series of linear actuators from Ultra Motion (Mattituck, NY) includes ABEC-7 angular contact bearings and interchangeable motor mounting plates. A Kevlar drive belt and pulleys provide 1:1, 2:1, 3:1, 4:1, and 5:1 drive ratios with low backlash and low audible noise by eliminating gears between the motor and the drive screw. There are 17 motor options including DC, DC servo, DC gearmotors, steppers, and Animatic Smart Motors. Absolute position feedback is available so that position is remembered if power is lost.

altTravel limits can be set at the controller, with an accuracy of ±0.0003" bidirectional and ±0.0001 unidirectional within the operating temperature range of -20°F to 120°F. Features include linear speeds from 0.001 to 20 in/sec, built-in end-of-stroke cushion, full stroke lengths from 2 to 8", and an actuation force of 500 lbs. A variety of mounting options is available, as well as optional magnetic switches, position feedback elements, and power-on or power-off brakes.
