The CRBU series is a free mount style, rotary actuator with direct mounting available in three directions.  Axial, vertical and side directions are possible.  Through the  adoption of specially designed seals and stoppers, a rotation angle of 270° has been achieved for the first time in a compact vane style actuator.  To support thrust and radial loads, bearings are used throughout the series.  In addition, rubber bumpers are  used internally (except size 10) to further improve reliability.
