Mounting Styles 2A Cylinder Mounting Styles The standard range of Parker 2A cylinders comprises 15 mounting styles, to suit the majority of applications. General guidance for the selection of the cylinders is given below, with dimensional information about each mounting style shown on pages 8 to 20 for 25.4mm to 152.4mm (1” to 6”) bore sizes, and pages 22 to 30 for 203.2mm to 355.6mm (8” to 14”) bore sizes. Application-specific mounting information is shown on pages 36 and 37. Where a non-standard mounting style is required to satisfy a particular application, our design engineers will be happy...

The heavy duty series 2A pneumatic cylinders described in this catalogue are of all-steel construction and are based on the Parker series 3L hydraulic range - see catalogue HY07-1130. They are exceptionally robust and are ideally suited for applications in steel mills, foundries, aluminium smelting plants or other arduous environments where normal light duty aluminium cylinders are not sufficiently durable. In addition to the standard cylinders featured in this catalogue, 2A cylinders can be designed to suit customer requirements. Our engineers will be pleased to advise on unique designs to suit...

Design Features and Benefits Gland seal life is maximised by manufacturing piston rods from precision ground, high tensile carbon alloy steel, hard chrome plated and polished to 0.2mm max. Piston rods are induction case hardened to Rockwell C54 minimum before chrome plating, resulting in a dent-resistant surface. For non-lubricated air cylinders, rod seals with special rounded sealing lips are supplied as standard. Specify series 2AN (see pages 34-35). The surface of the cylinder bore is finished to minimise internal friction and prolong seal life. The bore of the cylinder is hard chrome-plated...

Design Features and Benefits Piston Seals Needle valves are provided at both ends of the cylinder for precise cushion adjustment, and retained within the head and cap so that they cannot be inadvertently removed. The cartridge type needle valve illustrated below is fitted to cylinders of up to 63.5mm (21/2”) bore – see page 42. Lipseal Pistons – A Lipseal piston is fitted to 2A cylinders as standard. It offers a wide piston surface which reduces bearing load, and is suitable for speeds of up to 0.5m/s. Fully dynamic and self-compensating seals allow for variations in pressure, mechanical deflections...

Cylinder Selection Check List The following check list indicates the principal factors which should be considered when selecting a pneumatic cylinder for a particular application. Further information is available on the pages shown. If more detailed information is required about any aspect of a cylinder’s specification, please contact our design engineers who will be happy to assist. The European Cylinder inPHorm program can assist with the selection and specification of an hydraulic cylinder for a particular application. Please ask for HY07-1260/Eur. Establish System Parameters. . . . . . ....
