Rotary Actuator Vane Style/Free Mount StyleSeries CRBU/Size: 10, 15, 20, 30Rotation angles: 90°, 80°, 270°Up to 270° is possible in theentire seriesThrough the adoption of specially designed seals and stoppers,a rotation angle of 270° has been achieved for the firsttime in a compact vane style actuator.(Single vane style)Low pressure operationmade possibleThe special sealing construction that hasbeen adopted in the body supports a wideoperating pressure range and enable theentire series to be used at low pressures.Min. operating pressure• Size 10 ··································0.2 MPaSize 15, 20, 30 ······················0.15MPaStainless steel shafts andbolts(Carbon steel for size 30 and the double vane style)High reliability andlong lifeTo support thrust and radial loads, bearingsare used throughout the series. In addition,rubber bumpers are used internally (exceptsize 10) to further improve reliability.Double vane style standard: 90°, 100°The outside diameter is identical to the single vane construction (except size 10);however, due to the double vane construction, twice the torque of the single vanestyle can be obtained.Unrestricted auto switchmounting positionsBecause the switch can be moved anywhere along thecircumstance, it can be mounted in a position that is mostappropriate for the specifications.Port positions: body side and axial directionThe positions can be selected for ease of use. (Those that are equipped with various stylesof units can only be connected to the body side.)(On the body side)(In the axial direction)(Fittings are sold separately.)Block-built (units) adoptedVarious styles of units that can be housed within the body's outsidediameter can easily be retrofitted to the rotary actuator units of theentire series.Basic style + Switch unit(Fittings are sold separately.)Mountable without a flange evenwhen equipped with a unit.Basic style + Angle adjusting unit Basic style + Angle adjusting unit + Switch unit1.2-2

Direct Mounting In Three Directions PossibleMounting in three directions, axial, vertical and side, is possible.Three mounting variations are available in mounting in axial direction.Axial Direction Mounting StyleVertical Mounting StyleCRB1CRBUCRA1CRQMRQMSQMSUBSide Mounting StyleSimultaneous mounting in three directions ispossible. Therefore, it can be utilized in otherways apart from body mounting.Round Indication Board AdoptedIndication board mounted axially sets therotation range about the axis (one chamferingprocessed part) clear, and the indicationof connecting port (A/B port) locations preventswrong wiring.∗The above is an indication board of a single vane style.1.2-3
