37 Series C2E/C2/C2/C2 ydraulic Cylinder Precautions 1 Be sure to read before handling. Warning Design 1. There is a danger of sudden action by cylinders if sliding parts of machinery are twisted, etc., and changes in forces occur. 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 machinery should be designed and adjusted to avoid such dangers. 2. protective cover is recommended to minimize the risk of personal injury. If a driven objects and moving parts of a cylinder pose a serious danger of human injury, design the structure to avoid contact with the human body. 3. Securely tighten all stationary parts and connected parts so that they will not become loose. Especially when a cylinder operates with high frequency or is installed where there is a lot of vibration, ensure that all parts remain secure. 4. deceleration circuit or shock absorber, etc., may be required. When a driven object is operated at high speed or the load is heavy, a cylinder s cushion will not be sufficient to absorb the impact. Install a deceleration circuit to reduce the speed before cushioning, or install an external shock absorber to relieve the impact. In this case, the rigidity of the machinery should also be examined. 5. Consider a possible drop in operating pressure due to a power outage, etc. When a cylinder is used in a clamping mechanism, there is a danger of work dropping if there is a decrease in clamping force due to a drop in circuit pressure caused by a power outage, etc. Therefore, safety equipment should be installed to prevent damage to machinery and human injury. Suspension mechanisms and lifting devices also require consideration for drop prevention. 6. Consider a possible loss of power source. Measures should be taken to protect against human injury and equipment damage in the event that there is a loss of power to equipment controlled by air pressure, electricity or hydraulics, etc.. Design circuitry to prevent sudden lurching of driven objects. When hydraulic pressure in a cylinder is zero, the driven object will lurch at high speed if pressure is applied to one side of the piston. Therefore, equipment should be selected and circuits designed to prevent sudden lurching because, there is a danger of human injury and/or damage to equipment when this occurs. 8. Consider emergency stops. Design so that human injury and/or damage to machinery and equipment will not be caused when machinery is stopped by a manual emergency stop or a safety device under abnormal conditions such as a power outage.. Consider the action when operation is restarted after an emergency stop or abnormal stop. Design machinery so that human injury or equipment damage will not occur upon restart of operation. When the cylinder has to be reset at the starting position, install safe manual control equipment. Warning Selection 1. Confirm the specifications. The products advertised in this catalog are designed according to use in industrial oil hydraulic systems. If the products are used in conditions where pressure, temperature, etc., are out of specification, damage and/or malfunction may be caused. Do not use in these conditions. (efer to specifications.) Consult SMC if you use a fluid other than hydraulic fluid. 2. Intermediate stops Since hydraulic cylinders are not guaranteed for zero fluid leakage, it may not be possible to hold a stopped position for an extended period of time. 3. Consider surge pressure. Use cylinders which are able to withstand the surge pressures generated in hydraulic systems. (efer to specifications.) Nominal pressure: Pressure assigned to a cylinder for convenient identification. Not necessarily the same as the operating pressure which guarantees performance under specified conditions. Maximum allowable pressure: The maximum value which can be allowed for pressure generated inside a cylinder (surge pressure, etc.). 4. Consider compatibility with hydraulic fluids. ydraulic fluid eneral mineral hydraulic fluid W/O hydraulic fluids O/W hydraulic fluids Water/lycol hydraulic fluids Phosphoric ester hydraulic fluids Consult SMC regarding those marked with a " ". Caution Compatibility Yes Yes Yes 1. Operate within the limits of the maximum usable. The piston rod will be damaged if operated beyond the maximum. efer to the hydraulic cylinder model selection procedures for the maximum useable. 2. Operate the piston within a range such that collision damage will not occur at the end. Operate within a range such that damage will not occur when the piston having inertial force stops by striking the cover at the end. (1) To determine the operational range, take the load factor (page 26) into consideration, and refer to the load weight and speed charts. (2) When operating cylinders without cushion, lower the speed as the piston impacts the cover to mm/sec (approximately the speed that does not generate the sound of colliding metal parts), or install an external stopper. 3. Use a flow control valve to adjust the hydraulic cylinder drive speed, gradually increasing from a low speed to the desired speed setting. 4. Provide intermediate supports for long cylinders. In case of long cylinders, provide intermediate supports to prevent rod damage due to sagging of the rod, deflection of the tube, vibration and external loads. 34

38 Series C2E/C2/C2/C2 ydraulic Cylinder Precautions 2 Be sure to read before handling. Caution Mounting 1. Be certain to align the rod shaft with the load and direction of movement when connecting. When not properly aligned, twisting of the rod and tubing may occur, and damage may be caused due to wear 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. 3. Do not scratch or gouge the sliding parts of the cylinder tube by striking or grasping it with other objects. Cylinder bores are manufactured to precise tolerances, so that even a slight deformation may cause faulty operation. 4. Do not use until you can verify that equipment can operate properly. Verify correct mounting by suitable function and leakage inspections after piping and power is connected, following mounting, maintenance or conversions. 5. Instruction manual The product should be mounted and operated after thoroughly reading the manual and understanding its contents. eep the instruction manual where it can be referred to as needed. Caution Piping 1. Preparation before piping Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil and other debris from inside the pipe. 2. Wrapping of pipe tape When screwing together pipes and fittings, etc., be certain that chips from the pipe threads and sealing material do not get inside the piping. lso, when pipe tape is used, leave 1.5 to 2 thread ridges exposed at the end of the threads. Wrapping direction Expose approx. 2 threads Pipe tape 3. Set up so that air cannot accumulate inside piping. Caution Warning Cushions 1. eadjust using the cushion needle. Cushions are adjusted at the time of shipment, however, the cushion needle on the cover should be readjusted when the product is put into service, based upon factors such as the size of the load and the operating speed. When the cushion needle is turned clockwise, the restriction becomes smaller and the cushion's effectiveness is increased. 2. Do not operate with the cushion needle fully closed. When surge pressure is generated, the cylinder or equipment can be damaged. 3. Do not loosen the cushion needle too much. This can cause fluid to be blown out. Caution ir elease 1. Operate after opening the air release valve and completely releasing any internal air. esidual air can cause malfunction. 2. When adjusting the air release, do not loosen the plug too much. Use caution, because if the plug is loosened too much, it may fly out or fluid may blow out causing a danger of human injury. ydraulic luid 1. Use clean fluid. Do not use deteriorated fluid or fluid containing foreign matter, moisture or corrosive fluids, as this can cause malfunction and damage or corrosion of parts. Caution 1. Install hydraulic fluid filters. Install hydraulic fluid filters with a filtration degree of µm or finer in a hydraulic system. efer to SMC hydraulic filter specifications. 2. Use the product within the specified range of fluid and ambient temperature. Take measures to prevent freezing, since moisture in hydraulic fluid will be frozen under C, and this may cause damage to seals and lead to malfunction. Warning Operating Environment 1. Do not use in environments where there is a danger of corrosion. efer to the construction drawings regarding cylinder materials. 2. In dusty locations, or where there is exposure to chips and spatter, etc., install a protective cover, etc. When there is splashing or spraying of water or coolant, use water resistant hydraulic cylinders.
