ACTUATORS 1 ACT-191 For further information www.norgren.com EXAMPLE: Mini Rotary Actuator 3/4" Bore – Double Rack Integral Air/Oil Tandem Mini Rotary Actuator – 2 Position – 180° Rotation – Double End Keyway Output Shaft – Front Flange Mounting – Port Position 2 – No Bumpers – Rotation Adjustment End Caps B & D – FPM Seals. Single Rack and Pinion Mini Rotary Actuators are very compact. Rotation angles 45°, 90°, and 180° standard. Nitrile Noise Dampening Bumpers optional. FPM Seals optional for higher temperatures. Optional Low Friction Seals. Body Mount or optional Angle Bracket, Front and Rear Flange Mountings. Technical features Medium: Filtered compressed air to 150 PSI (10 Bar) Operating Temperature: -20°F to 200°F (-29°C to 93°C) with Standard Nitrile Seals -20°F to 400°F (-29°C to 204°C) with FPM Seals -20°F to 250°F (-29°C to 121°C) with Low Friction Seals Operating Pressure: 150 PSI (10 Bar) Angle of Rotation: 45°, 90°, 180° Standard Other rotations available Rotational Tolerance: -0° + 1/2° Backlash Between Rack & Pinion: 2 position units less than 1° of arc maximum NOTE: For 0° backlash at each end of rotation, specify a double rack actuator with rotation adjustments. Lubrication: None required Norgren Rotary Actuators are rated for "no lube added" service. All internal components are lubricated at the time of assembly with a PTFE based grease. Recommended fluid for air/oil tandem is petroleum based hydraulic oil, non-foaming, non- detergent ISO Viscosity grade of 46. Materials End Caps: Black anodised 6061-T6 aluminum Body: 6061-T6 aluminum alloy, entirely black anodised Gear Rack: Ground and polished stress proof steel Pinion Gear and Output Shaft: Manufactured as one piece from high strength steel. Shaft Bearings: SAE 841 Bronze Standard Seals: Nitrile Ordering information Model codes Options Substitute No Option 0 Electroless Nickel E FPM Seals V Switches Substitute N/A 0 Rotation Adjustments Substitute No Adjustment 1 End Cap A 2 End Cap B 3 End Caps A & B 4 End Caps B & D 5 Bumper Substitute No Bumpers A End Cap A B End Cap B C All Caps D Flow Controls Substitute N/A A Cushions Substitute N/A A Port & Location Substitute Port Position 1 A* Port Position 2 B Port Position 3 C Port Position 4 D Port Position 5 F *Standard Port Location Bore Substitute 1/2" 0 3/4" 1 Rack/Rotary Type Substitute Single Rack Standard Seals 0 Single Rack Low Friction Seals 1 Double Rack Low Friction Seals 2 Double Rack Standard Seals 5 Double Rack Integral A/O Tandem Standard Seals (ø 3/4" Bore only in mini rotary) 7 Multiple Position Actuator Substitute 2 Position O Rotation Substitute 45° A 90° B 180° C Output Shaft Substitute Single End Keyway Standard A Double End Keyway B Mounting Substitute Standard 1 Front Flange 2 Rear Flange 3 Angle Bracket 5 1 7 0 C B - 2 B A - A A 5 0 V Rack & Pinion Rotary Actuators Single, Double, and Integral Air/Oil Tandem Rack & Pinion Mini Rotary Actuators (ø1/2" & 3/4" Bores)
