Shock Absorbers - Parker Hannifin GmbH - #9

Text version of the page

Sélection of Shock Absorber Type ORIGA shock absorbers are available in two main types, to suit différent applications and installation requirements. After selection of the appropriate type, sizing is determined by calculation. Compact series with full-length body thread This compact, space-saving series is available in adjustable and non-adjustable versions and can be installed in many different ways, e.g. in a tapped blind hole, in a tapped through-hole, in a clearance hole in a flange or bracket, etc. Accumulators Normally shock absorbers with internal accumulators are used. This simplifies installation by eliminating external piping and oil storage. However, in applications with short cycle times and high kinetic energy the oil can become overheated. In this case an external accumulator should be used so that the oil can be cooled in the external circuit. Shock absorber return stroke ■ Piston rod with return spring combined with internal accumulator ■ Return stroke actuated by compressed air or mechanically, combined with ex­ternal accumulator. With this version a delayed return stroke is also possible. Options ■ Stop collars for front or rear mount­ing - these provide a positive stop to prevent damage caused by the piston „bottoming out". They also allow precise setting of the stroke length. ■ Soft pad for the hardened steel button - to avoid surface damage and reduce noise levels. Universal series This versatile, adjustable series with various mounting accessories is designed to stop heavier loads. It is especially suited to applications which require several of the same shock absorbers with the same stroke length. Mounting methods ORIGA shock absorbers are designed for a variety of mountings, which can be either built into machines or supplied as accessories.
