2 Data Operating Principles & Internal Construction On impact by mass material in motion, the piston rod gradually moves into the shock absorber and stops up the orifices (Deceleration of cross section of orifice) and the hydraulic fluid in inner tube spurts out outer tube throughout the orifices and the hydraulic fluid flows in the top end of the inner tube throughout the oil returning hall and the excess hydraulic fluid gets stored in accumulator temporarily. At the end of the impact stroke, the return spring pushes the piston and the hydraulic fluid flow into inner tube rapidly throughout check valve for next cycle. This system absorbs the impact shock gradually and at a constant rate (Deceleration of cross section of orifices and deceleration ratio of the piston back speed) and the piston transfer is smooth and quiet. Effective Weight The effective is absorbed real impacting quantity of energy during the period between colliding a moving object to shock absorber and stop of a moving object. The left drawing (A) shows that even if real is too small, in case of impacting velocity is sufficiently high (more than 3m/sec), the effective section of orifice needs to be increased because of generating high resisting force at the beginning of motion object collide. Example The left drawing (B) shows that even if the colliding velocity is too low (less than 0.5m/sec), effective section of orifice needs to be decreased when the is sufficiently ed or additional driving force occurs as high resist force generates at the end of stroke. As known to see figure even though the motion object has same and velocity, the impacted real energy on shock absorbers has big difference in accordance with propelling force and existence shock absorber or not. Impact without propelling force W E =m Impact without torque W E =m Example Example Impact with propelling force Example At first compare to, in case of which received propelling force is three times bigger than in case of Example And in case of, even though these have same Kinetic energy, real impact energy of increased sixteen times more than in case of, according to location of shock absorber. As above even though same and velocity, it must be considered not only total energy but also effective when the model is selected, because real impact energy received from shock absorber is quite different according to cases.

It can be adjustable along with variable impact energy as well as displays the amount of force from 0 to 8 according to opened grade. & KSCA Non-Adjustable A non-adjustable shock absorber includes fixed orifices is made by choosing only advantages of each Hydro and Adjustable so that it can absorb a more wide range of effective. Also it can exhale heat energy changed from absorbed impact energy within a short time. The non-adjustable shock absorber that is specially designed for non-adjustable brings the impacting object to a stop smoothly and quietly for maintaining a constant discharge,, velocity, temperature and hydraulic status.

6 Data A. Precaution of Selection 1. Finding out satisfied mode with Ec value, Ed value and We value in capacity chart after result out. 2. Even though it is small and the impact cycle per hour is high, it seems that the Ed value is too high and the We value is too low, relatively. Even in such a case must choose the model which Ed value and We value within range simultaneously. 3. Durability of shock absorber remarkably can debase if it depends on only We value without consideration of number of impact times per hour. 4. Choose one of 40~80% the capacity chart for safety. 5. It must be designed perpendicular to the collided object and shock absorber (In case the angle of declination is more than 1.5 degree, that can cause oil leakage as seal overload.) 6. Design to be perpendicular to the weighed direction of object and an axial of shock absorber in case of shaking impact. (Make allowance angle to end of stroke 2 <1.5, in such a case, minimum installation radius shown in the following table. In case of more than 1.5 degree might cause oil leakage.) * Installation condition of shanking condition Model Stroke Acceptance angle 2 KSCA KSCA KSCA KSCA B. Precaution of Circumstance 1. Don t use with pressure, vacuum, or any circumstance different from the pressure of the atmosphere. 2. Do not use in clean room. It might cause air pollution. 3. Do not use over the allowed temperature, because oil leakage may occur as the result of harden, soften and wear of the seal. 4. It can not return smoothly in initial as working oil viscosity rise at temperature below zero in winter. It can work smoothly after working more than 20 times repetition. So Keep that in mind in use. 5. Don t use in the circumstance of solvent, as it will corrode the metal and possibly compromise the seal. 6. If possible, avoid using in conditions that have influence on the piston rod directly, or spray, such as cutting near oil, water, various solvents, etc. C. Precaution of Installation 1. Make protector when the impact object vibrates. 2. Make the contact point in a straight line and allow slide angle to be less than 1.5 degrees. 3. Avoid damage to the piston rod or threads. Damaged piston rod can cause oil leakage and damaged threads can cause the inner component to deform and loose shock absorption. 4. Replace the shock absorber with a new one when strange colliding noises and vibration occur. 5. When tightening nut, use K portion with a spanner. Take care avoid damaging outer tube and threads. Model K Model K KSCA KSCA D. Maintenance 1. Check tightening nut and tighten periodically, because the shock absorber may be damaged when using with loose nut. 2. The lifespan of the shock absorber is limited. Replace shock absorber if you hear strange colliding noises or vibration. Continued use of a worn shock absorber can cause equipment damage. 3. Confirm that the cap is not damaged. Sometimes the cap damage comes first in case of cap attachment type. Change the cap as soon as possible in order to prevent damage

18 Data What is? -Inside the closed cylinder of gas spring, compressed nitrogen gas and little volume of oil are injected, and the structure of it is that the pressure of nitrogen gas exerts to the section of the piston rod, and thus repulsive force can be acquired. Due to this structure, it has following features, and thus it may widely be used for various industrial machines, furniture, home appliance, OA machine, and athletic equipment as well as automobile. Features It can absorb impact and vibration, and can open, close and move an object such as a cover with little force. Comparing to a coil spring or a plate spring, it is small and light, but has a big repulsive force. In a section between all strokes of it, relatively constant repulsive force can be acquired. Setting-up of working speed combined with extension is possible. Attachment and detachment of the gas spring are easy. Designing in accordance with use and widely ranged application are possible. Precautions Do not dismantle the product or do not put it into a re. For use, attach it with the cylinder upward direction. Do not paint at the piston rod, or do not put a foreign object into it, and do not make a scar on the surface of it. Use it within the range of 0~ 40. Do not use it at a place where corrosion may be expedited, and rain / water is contacted, or humidity is high. When you discard it, wear protective goggles, make a hole with a drilling tool about 3mm size at the position of 25mm from the end of cylinder like the gure. After gas is discharged then discard it

19 Data Decision of Repulsive Force (F 1 ) Graph of Repulsive Force ) Setting-up repulsive force can be sought by following formula, and it can be decided with consideration of temperature and other conditions. F 1 = W L1 L2 N L1 = Horizontal distance parallel with the earth surface from the hinge to the central point of the of the door L2 = Vertical distance from hinge to the central line of the gas spring W = Weight of the door N = Quantity of the gas spring to be attached Please make the really repulsive force of the product to be higher than F1x1.2 (safety factor). For the life span and the safety of the hinge, etc., please apply more than two. & KSCA KBG-W A = Repulsive force of position where piston rod is compressed 10mm B = Repulsive force of 10mm position right before expanding a piston rod fully C = Repulsive force of 10mm position right before compressing a piston rod fully D = Repulsive force of position where piston rod is expanded 10mm again after compressing it 10mm KBG-B Variation Ratio of Compression vs Variation Volume of Temperature In accordance with abnormal gas equation, the repulsive force for every 10 temperature of the variation changes by 3.4% each. In accordance with this, considering the constant temperature of product applied to the gas spring, the repulsive force is determined. However, with small quantity of oil injected inside and the change of viscosity of grease, etc,. the real value may be changed differently
