Humphrey Guided Linear Actuators add support and precision to the extending and retracting functions of linear actuators. Cross-roller bearing linear rails, multiple rods and/or guide shafts are employed with the actuator to withstand compound or lateral loads and ensure precise movements and positioning of work piece. Additional design and cost considerations, such as miniaturization, mounting, stroke adjustment, position sensor conveniences, and RoHS compliant materials round out this offering.
