The Bug series of linear actuators from Ultra Motion feature ABEC-7 angular contact bearings and interchangeable motor mounting plates. A Kevlar drive belt and pulleys provides 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 even if power is lost.

Travel limits can be set at the controller, with an accuracy of ±0.0003 in. bidirectional and ±0.000 unidirectional within the operating temperature range of -20&#176 to 120&#176F. Linear speeds from .001 to 20 ips, built-in end of stroke cushion, full stroke lengths from 2 to 8 in. and an actuation force up to 500 lb are featured.
