N O R G R E N LINTRA RODLESS CYLINDERS Features Lintra rodless cylinders require less space for installation since the stroke of the cylinder is contained within the length of the cylinder itself. Non-rotating load carrying capability without additional expensive guide rods and bearings Equal forces can be applied to each stroke direction. Extreme stroke lengths are available up to 28 ft. Lintra features a wide range of bore sizes: 20 mm bore 40 mm bore 63 mm bore 25 mm bore 50 mm bore 80 mm bore 32 mm bore Magnetic piston standard Integral switch rail on both sides of the extrusion. Components are made of anodized, corrosion resistant aluminum Cushion adjustment standard at both ends of the cylinder. Stroke velocities up to 98 ft/sec are available. The Lintra is designed for easy maintenance. Lintra cylinders can withstand heavy loads and inertial moments. Polyurethane seals provide long life. Operating Specifications Operating Temperature -22 to 180F* Operating Pressure 16 mm: 22 to 150 psig 20 mm to 80 mm: 15 to 150 psig Stroke lengths: 20 mm to 40 mm bore-to 28 ft. 50 mm and 63 mm bore-to 23 ft. 80 mm bore-to 18 ft. Supply Fluid: Compressed air filtered to 50-microns and lubricated. Materials of Construction Tube and Carriage: Anodized aluminum End Caps: 20 mm-anodized aluminum end covers, molded plastic yoke. 25 to 80 mm-anodized aluminum end caps and yoke. Seal Strips and Piston Seals: Polyurethane Cover Strips: Polyamide Guide Rails: UHMW Polymer Seals: Nitrile rubber or Polyurethane THRUST-Based on 75% of Maximum Thrust Cushioning Performance The dynamic energy of a Lintra cylinder is caused by direct or partial external loads which must be absorbed by pneumatic cushioning. The cushioning ability depends to a large extent on the pneumatic circuit (e.g. counter pressure, pre-exhaust). The values given in the diagram were tested with an operation pressure of 87 psig using a 5/2 control valve. When installed horizontally, depending upon the speed, dynamic energy can be absorbed by the cylinder. Whenever the values given in the diagram are exceeded, the transported mass must be cushioned by additional shock absorbers. These have to be located at the center of gravity of the mass. The Extruded Tube of the Lintra Series 46000 Cylinder Vee-guides provide for the installation of guiding and mounting elements. Extrusion configuration resists flex and provides superior torsional stiffness, allowing greater loads with less deflection. Clear coat anodized corrosion resistant aluminum Integral reed switch rails Magnetic piston is standard, simplifying the addition of position sensing switches Anodized, corrosion resistant extruded aluminum tube Three carriages available, all designed for large load carrying capabilities Extrusion has inte- gral slots for position sensing switches Polyamide cover strip, Polyurethane seal strip Integral wiper Extrusion configuration increases resistance to torsional stresses Vee-guides along the length of the tube allow for installation of roller guided carriages and brake systems The left end cap is dual ported to allow both air connections to be made at one end. By removing the plug from the lower port of the left end cap and plugging the right end cap port, cylinder inlet and exhaust can be plumbed from the left end cap.
