8 SUPERCYLINDER FEATURES & BENEFITS FOR HAZARDOUS CONDITIONS Duff-Norton now offers new models of our popular SCN and SCW Series SuperCylinders with motors and limit switches rated for hazardous locations. CERTIFICATIONS Motors are available for Class 1, Group D and Class 2, Group F & G environments (as defined in NFPA Publication 70). Limit switches are marked either NEMA 7 for use in Class 1, Group D locations, or NEMA 9 for use in Class 2, Group E, F & G locations (as defined in NFPA Publication 70). The SCN Series combines the ball screw driven translating tube system with trunnion mounted high-efficiency helical or helical-bevel, oil filled gearboxes. The SCW Series combines a ball screw or ACME screw driven translating tube system with our existing clevis mounted worm gear actuators. Both Duff-Norton SuperCylinder series use a precision guided translating tube system to broaden application capabilities. A ground and chrome plated translating tube sliding in polymeric bearings produces excellent resistance to buckling. This lets SuperCylinders achieve stroke lengths much greater than are possible with conventional double clevis mounted mechanical actuators. Enclosure of the screw by the tube system shields it from environmental contaminants and retains lubricants, requiring less maintenance and allowing longer service. SuperCylinders use hydraulic cylinder grade wiper seals to effectively exclude dirt from the screw area. The modular concept employed by Duff-Norton for both SuperCylinder series allows an unlimited number of configuration possibilities for tailoring of the SuperCylinder to an application. The selection of available gear ratios is unmatched by any similar product. This exceptional choice of ratios allows precise tailoring of the actuator speed and load specifications. Many additional motor and ratio options are available to meet specific capacity, speed, or life requirements. Speeds Up To 379 in/min Capacities Up To 50,000 lbs Aluminum Bronze Worm Gears (SCW Series) Strokes Up To 161 inches Continuous Duty Ratings (SCN Series) Ball Screw or Acme Screw Low Power Requirements (SCN Series) Clevis Mounting or Trunnion Mounting Helical & Helical Bevel Gears (SCN Series) NOTE SuperCylinders do not incorporate any protection against mechanical overloading, either externally applied or through internal jamming. In applications where overloading is a possibility, appropriate electronic or mechanical devices should be incorporated to prevent operation of the actuator if overloaded. WARNING The equipment shown in this catalog is intended for industrial use only and should not be used to lift, support, or otherwise transport people unless you have written statement from Duff-Norton Company, which authorizes the specific actuator unit as used in your applications suitable for moving people.

30 LINEAR ACTUATOR HOW TO ORDER (NZ, NL, and NU Series) 1. Specify model from tables (example: NLEX-0385) 2. Specify stroke, available in 1 inch increments. Maximum stroke may be limited by column buckling strength, and varies with load rating. Contact factory to confirm availability of any stroke over 54 inches. Units are designed so that there is 1/2 inch overtravel before internal jam in both the retracted and extended positions. 3. Specify fitted horsepower. This can be the standard model horsepower shown in the charts or a different horsepower determined by life vs. load. Contact our application engineers for more information. 4. Specify voltage. Standard voltage is 230/460 volt, 3 phase, 60 Hz. For other voltage requirements, contact our application engineers. 5. Specify mounting position (see charts, page 11). This is required to allow proper oil filling of the gearbox. Choose position that most closely matches actual installed position. 6. Specify mounting blocks if needed. See page 16 for mounting information. 7. Model nomenclature: NZ N-series SuperCylinder Z, L, or U layout Static rating in tons Gear ratio, (example = 12.23) Factory assigned configuration number Intrinsically safe potentiometer feedback option Hazardous-duty SuperCylinders are available with a potentiometer in a standard NEMA 4 enclosure that can be used with an intrinsically safe barrier when properly installed.

Please review the following formulas carefully, and feel free to contact our customer service department with questions. Screw Specifications: Dia x Lead (in) D min L 10 Rating Max RPM 1.00 x x x , Max RPM = maximum screw speed due to ball velocity limit. L 10 rating = Load (lbs) to produce 10% failure rate after 1,000,000 inches of travel. D min = Screw minor dia.(in.) Design Formulae: Speed (in/sec) = Screw Lead x Motor RPM 60 Capacity (lbs) = 5.65 x Motor torque (in-lbs) Screw Lead Motor torque (in-lbs) = Horsepower x RPM [ ] 3 Screw Life (million inches of travel) = L 10 Rating x Screw Lead Load NOTE Critical Speed: High speed rotating shafts are subject to destructive vibrations. To prevent instability, the speed and length must be held within limits per the following equation: RPM max = 1.37 x 10 6 x D min L 2 where L = Actuator stroke (inches) This equation for critical RPM includes a 0.80 factor of safety.

72 SUPERCYLINDER MOUNTING COMPONENTS TRUNNION BLOCKS ANSI Standard through holes, and black oxide finish ANSI Standard tapped holes, and dust seal Duff-Norton SCN and SCD SuperCylinders are available with trunnion mounting only and are fitted with trunnion pins as standard. The trunnion pins are designed to fit standard dimension radial spherical plain bearings (Torrington type SF, or SKF type GEZ, for example). Duff-Norton offers Trunnion Blocks to facilitate the installation of SCN and SCD series SuperCylinders. These blocks are solid steel and house properly sized spherical plain bearings. The blocks are drilled for mounting either as a conventional pillow blocks or as a flange units. Heat-treated fasteners should be used for all attachments. If Duff-Norton Trunnion Blocks are not chosen for the SuperCylinder s installation, we strongly recommended that the trunnion pins be supported by some type of self-aligning bearing, as perfect alignment of trunnion support bearings is difficult to achieve. Standard pillow blocks are not recommended, as their maximum static load rating is usually less than that of the SuperCylinder. In addition, most pillow blocks use gray cast iron frames, which are subject to fracture under heavy loads.
