26 26 Issue7.2014 Specifications subject to change MiniatureShockAbsorbersMA Adjustable Adjustment: OnmodelsMA30up toMA150: by turning the adjustment screwat rear.On the larger sizes: by turning theadjustment knobagainst the scalemarked0 to9. After installation, cycle themachine a few times and turn the adjustment systemuntil optimumdeceleration is achieved (i.e. smoothdeceleration throughout stroke). Hard impact at the start of stroke: Adjust the ring towards9or PLUS. Hard impact at theendof stroke: Adjust the ring towards0orMINUS. Impact velocity range: MA30M: 2.2 to14.6 ft/sec MA35: Max. 3.3 ft/sec MA50M: 2.4 to5.2 ft/sec MA150, 225, 600, 900: 0.5 to12 ft/sec Material: Shock absorber body: Nitridehardened steel. Accessories: Steel withblack oxide finishor nitridehardened. Piston rod: Hardened stainless steel. E 4 capacity rating: (max. energy per hour, in-lbs/h) If your application exceeds the tabulatedE 4 figures consider additional cooling i.e. cylinder exhaust air etc. AskACE for further details. Mounting: In any position. If precise endposition is required, consider useof theoptional stop collar. Operating temperature range: 32 °F to150 °F On request: Corrosion-resistant WeartecPlus outer tube coating is standard. Other coatings and constructionmaterials are available upon request.

If youprefer a fully adjustable shock absorber rather than a self-compensating model on your application then the MAseries provide adirectly interchangeable alternative. The adjustable series include an integrated mechanical stop. These adjustableunits have long stroke lengths (MA900with1.57 inches superstroke) toprovide smoothdeceleration and low reaction forces. TheMA150 incorpo- rates theproven rollingdiaphragm seal (used on theMC150 toMC600 range) and shares all the advantages of that technology. The step- less adjustment rangeof theMA series covers aneffectiveweight range from0.5 lbs up to 4,500 lbs.
