RR-18 Light-Duty Rotary Actuator
Ultra-thin profile for tight spaces, preloaded bearings for repeatable motion, zero backlash via slip-fit dowel pins, and built-in adjustable hard-stops.
Optional rotary manifold prevents twisted airlines; CR option supports clean-room/harsh environments. Common uses: precision rotary positioning, medical/OEM equipment.
