The Bug series of linear actuators from Ultra Motion has been redesigned to offer improved strength, precision and reliability; while keeping the same footprint. New features of the series include 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 to √Ç¬±0.0003 in. bidirectional and √Ç¬±0.0001 unidirectional within the operating temperature range of -20° to 120°F. Linear speeds range from 0.001 to 20 ips, there is a built-in end of stroke cushion, full stroke lengths range from 2 to 8 in. and actuation forces up to 500 lb are possible.
