Shock AbSOrblki Series NRB Automatic adjustment absorption performance Specially designed orifice can absorb energy comprehensively and most appropriately in many different applications These range from high speed low load, to low speed high load; without requiring additional adjustment of the shock absorber. Piston stroke/displacement wave pattern Double seal enclosure Scraper and rod seal combine to form a double seal enclosure preventing oil leakage, thus maintaining the long life amping to meet the high odern world. Improved resistance against deviation Due to a newly designed high load...

How To Select An Applicable Model Ensure that both the impact velocity and the ambient temperature fall within the specifications of S Calculation of kinetic energy (E,) Calculate kinetic energy E, using the equation suitable for the classification of impact._ In the case of cylinder with load and free horizontal impact, substitute respective figures for graph @ in order to calculate E,. [5] Calculation of work energy (E2) Select any shock absorber as a provisional model and calculate work energy E2. In the case of work energy of cylinder, substitute respective figures for table @ or graph...

©Load should always be aligned with the axis of piston rod. (In the case of eccentricity of 3° or more, please contact ©For rotational impact, load should always be aligned perpendicular to the axis of shock absorber and allowable rotation angle at stroke end should always be 92<3° (In the case of rotation angle of 3° or more, please ©Adjustment of the stopper nut (to adjust the length a) will control the suspension time of the impacting object. S: Stroke of Shock absorber (Figures specified on cataioaue) ©Avoid applications where the shock absorber rod is in direct contact with cutting...
