! Be sure to read before handling. Refer to pages 10-24-3 to 10-24-6 for Safety Instructions and Actuator Precautions, j Select a model so that the aggregated energy of impact object should not exceed the maximum absorption energy. Otherwise, it could cause changes in properties or result in damaging the shock absorber. 2. Corresponding weight of impacting object Make a model selection, so that the corresponding weight of impacting object does not exceed the allowable range. Pulsation will occur in buffer and deceleration force, thus making it difficult to absorb shock smoothly. Use it in the...

Shock Absorber Series RB ! Be sure to read before handling. Refer to pages 10-24-3 to 10-24-6 for Safety Instructions and Actuator Precautions. If rotating impacts are involved, the installation must be designed so that the direction in which the load is applied is perpendicular to the shock absorber's axial center. The allowable rotating angle until the stroke end Allowable rotating eccentric angle 82 < 3C Installation Conditions for Rotating . Do not scratch the sliding portion of the piston rod or the outside threads of the outer tube. Failure to observe this precaution could scratch or gouge...

Safety Instructions These safety instructions are intended to prevent a hazardous situation and/or equipment damage. These instructions indicate the level of potential hazard by labels of "Caution", "Warning" or "Danger". To ensure safety, be sure to observe ISO 4414 Note 1), JIS B 8370 Note 2) and other safety practices. Caution : Operator error could result in injury or equipment damage. Warning : Operator error could result in serious injury or loss of life. Danger : In extreme conditions, there is a possible result of serious injury or loss of life. Note 1) ISO 4414: Pneumatic fluid power--General...

Be sure to read before handling. For detailed precautions on every series, refer to main text. 1. There is a possibility of dangerous sudden action by air cylinders if sliding parts of machinery are twisted due to external forces, In such cases, human injury may occur; e.g., by catching hands or feet in the machinery, or damage to the machinery itself may occur. Therefore, the machine should be adjusted to operate smoothly and designed to avoid such dangers. 2. A protective cover is recommended to minimize the risk of personal injury. If a stationary object and moving parts of a cylinder are...

Actuator Precautions 2 Be sure to read before handling. For detailed precautions on every series, refer to main text. Mounting Caution Cushion Caution 1. Be certain to match the rod shaft center with the load and direction of movement when connecting. When not properly matched, problems may arise with the rod and tube, and damage may be caused due to friction on areas such as the inner tube surface, bushings, rod surface, and seals. 2. When an external guide is used, connect the rod end and the load in such a way that there is no interference at any point within the stroke. 3. Do not scratch...

Be sure to read before handling. For detailed precautions on every series, refer to main text. Operating Environment Do not use in atmospheres or locations where corrosion hazards exist. Refer to the construction drawings regarding cylinder In dusty locations or where water or oil, etc., splash on the equipment, take suitable Use the heavy duty scraper type (-XC4) in situations where there is a lot of dust. Use a water resistant cylinder when there is splash or spray of liquids. When using auto switches, do not operate in an environment with strong magnetic fields. 1. Do not use air-hydro cylinder...
