1 ACTUATORS ACT-196 For further information www.norgren.com Single Rack Shown Rotational Velocity Maximum rotational velocity of a rotary actuator is difficult to determine due to varying factors such as pressure, medium, flow and external loading. Excessive speeds in a given application can create inertia loads whose shock values could prove detrimental to the actuator. Use of external stops, cushions, or other deceleration devices will ensure maximum performance and actuator life. Seal Kits Standard Low Friction FPM Air/Oil Tandem Bore Part No. Part No. Part No. Part No. 1-1/8" Single Rack 200SK 200TK 200VK We recommend that Air/Oil Tandems are returned to the factory for repair. 1-1/8" Double Rack 250SK 250TK 250VK 1-1/2" Single Rack 300SK 300TK 300VK 1-1/2" Double Rack 350SK 350TK 350VK 2" Single Rack 400SK 400TK 400VK 2" Double Rack 450SK 450TK 450VK 2-1/2" Single Rack 500SK 500TK 500VK 2-1/2" Double Rack 550SK 550TK 550VK Rotary Actuators are constructed with the finest materials for each component! 1 Floating Pistons: Solid aluminum alloy, lightweight for low inertia, yet strong. Provide excellent wear characteristics against the hard coated tube I.D. 2 Seals: Lip type, pressure sensitive nitrile seals are wear compensating for long service life and minimum friction. 3 Actuator Body: Precision machined from 6061-T6, 40,000 PSI minimum yield aluminum alloy for strength. The entire body is then hard- anodised for maximum wear and corrosion resistance. 4 Grease Fitting: Easy access for additional lubrication. Single rack located on top; double located on top and bottom. 5 Retainers: Aluminum plates are located on the front and rear of the actuator body to ensure positive retention of the pinion/shaft/bearing assembly. 6 Tie Rods: Stress-proof steel to maintain compression on the tube end seals. 9 10 45° – 90° – 180° – 270° – 360° rotations are standard and available in single or double rack models. Other rotations available up to 1080°. 1 2 3 4 5 6 12 8 11 8 7 7 Rotation Adjustment (optional): Up to 30° angle. 8 End Caps: Machined from 6061-T6 solid aluminum bar that is anodised for corrosion resistance. 9 Rack: Ground and polished stress-proof steel. 10 Shaft Bearings: Sealed, single row ball bearings provide exceptional shaft stability with a low coefficient of friction. 11 Pinion and Output Shaft: Manufactured from high strength steel for maximum strength and endurance. A keyed output shaft is standard with other shaft options available. 12 Tube: 6063-T832 aluminum alloy which is ideally suited for air service. The tube is clear anodised on the O.D. and "hard anodic coated" on the I.D. which results in a smooth, file hard (60RC), corrosion and score resistant surface finish. Options not shown: Low Friction Seals, Cartridge Speed Controls,High Temperature FPM Seals, Adjustable Cushions, Bumpers, Magnetic Piston for Position Sensing, Multi- Position Rotation Capabilities.
