22 Series CS Technical ata 1 ore Size Selection Relationship among generated force, bore size and pressure cylinder s generated force will be lower than the theoretical output due to the following factors. (1) Sliding resistance on the cylinder bearings, seals, etc. () Pressure loss in hydraulic equipment and piping (3) rictional resistance in moving parts of machinery It is necessary to select bore sizes considering these factors. When a cylinder is nearly at rest, the relation of generated force, bore size and pressure can be expressed with the following formulas. p1 = µ1 f1 ormula (1) p = µ f ormula () π f1 = P 4 ormula (3) π f = ( -d ) P 4 ormula (4) p1: enerated extension force of cylinder (N) p: enerated retraction force of cylinder (N) f1 : Theoretical extension output (N) f: Theoretical retraction output (N) P : Operating pressure (Pa) : ore size d : Piston rod diameter µ1 : Cylinder extension load pressure coefficient 0. µ : Cylinder retraction load pressure coefficient 0. Selection standards The ratio of the load to the theoretical output is the load factor. It is imperative to understand the relationship between this load factor and the piston speed in order to make the proper bore size selection. Use the table below as a guide for understanding the correlation between load factor and piston speed. Piston speed (mm/s) to 1 to to 0 aximum load factor 0% % % Selection Example To find the cylinder bore size that is required to operate: On a load weight of 00N. With operating pressure of Pa.

The values in these tables indicate the maximum stroke that can be used in a situation when air is being supplied while the cylinder is stopped in an intermediate position by an external force acting on the piston rod, or by external stopper, etc. Since the maximum usable stroke varies depending on the diameter of the piston rod and operating conditions, verify the applicability using the stroke range limit chart.

Note 1) ISO 43: Pneumatic fluid power -- eneral Rules for Pneumatic Equipment Note ) IS 1: Pneumatic system axiom Warning 1. The compatibility of hydraulic equipment is the responsibility of the person who designs the hydraulic system or decides its specifications. Since the products specified here are used in various operating conditions, their compatibility for the specific hydraulic system must be based on specifications or after analysis and/or tests to meet your specific requirements. The expected performance and safety assurance will be the responsibility of the person who has determined the compatibility of the system. This person should continuously review the suitability of all items specified, referring to the latest catalog information with a view to giving due consideration to any possibility of equipment failure when configuring a system.. Only trained personnel should operate pneumatically operated machinery and equipment. Compressed hydro can be dangerous if handled incorrectly. ssembly, handling or repair of hydraulic systems should be performed by trained and experienced operators. 3. o not service machinery/equipment or attempt to remove components until safety is confirmed. 1. Inspection and maintenance of machinery/equipment should only be performed after confirmation of safe locked-out control positions.. When equipment is to be removed, confirm the safety process as mentioned above. Cut the supply pressure for this equipment and exhaust all residual compressed air in the system. 3. efore machinery/equipment is restarted, take measures to prevent shooting-out of cylinder piston rod, etc. 4.

Installation on equipment in conjunction with atomic energy, railway, air navigation, vehicles, medical equipment, food and beverages, recreation equipment, emergency stop circuits, clutch and brake circuits in press applications, or safety equipment. 3. n application which has the possibility of having negative effects on people, property, or animals, requiring special safety analysis.

29 Series CS ydraulic Cylinder Precautions 1 e sure to read before handling. Warning esign 1. There is a possibility of dangerous sudden action by cylinders if sliding parts of machinery are twisted due to external forces, etc. In such cases, human injury may occur; e.g., by catching hands or feet get caught in the machinery, or damage to the machinery itself may occur. Therefore, the machine should be designed to prevent such dangers.. protective cover is recommended to minimize the risk of personal injury. If a stationary object and moving parts of a cylinder are in close proximity, personal injury may occur. esign 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. Cases when a deceleration circuit or shock absorber may be required. When a driven object is operated at high speed or the load is heavy, a cylinder's cushion will most likely 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. When a cylinder is used as a clamping mechanism, there is a danger of work pieces dropping if there is a decrease in clamping force due to a drop in circuit pressure caused by a power outage. Therefore, safety equipment should be installed to prevent human injury or damage to machinery. Suspension mechanisms and lifting devices also require for drop prevention measures. 6. Consider a possible loss of power source. easures 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.. esign 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.. Consider emergency stops. esign the system so that bodily injury and/or damage to machinery and equipment will not occur when machinery is stopped by a manual emergency stop or a safety device triggered by abnormal conditions.. Consider the action when operation is restarted after an emergency or abnormal stop. esign machinery so that bodily insury or equipment damage will not occur upon restart of operation. When the cylinder has to be reset at the starting position, install manual safely equipment. Warning Selection 1. Check the specifications. The products featured in this catalog are designed strictly for use in industrial oil hydraulic system applications. If the products are used in conditions that are outside the range of pressure and temperature specifications, damage and/or malfunction may occur. o not use in these conditions. (Refer to specifications.) Consult with SC if a fluid other than hydraulic fluid is to be used.. Intermediate stops Since hydraulic cylinders are not guaranteed for zero oil leakage, it may not be possible to hold a stopped position for an extended period of time. 3. Take surge pressure into consideration. Use cylinders which can withstand the surge pressures (maximum allowable pressure) generated in hydraulic systems. (Refer to specifications.) Inside cylinders, pressure may be generated that is higher than the set pressure for the relief valve, e.g., internal pressure due to load inertia or surge pressure when switching valves. Consider these factors and determine the operating pressure so that the pressure generated inside cylinders will be within the maximum allowable pressure. Pressure terminology used in this catalog is defined as follows: Nominal pressure: Pressure assigned to a cylinder for convenient identification.it is not necessarily the same as the operating pressure which guarantees performance under specified conditions. aximum allowable: The maximum allowable value for the pressure that is pressure generated inside cylinders (such as surge pressure). Proof pressure: Test pressure that the cylinder must be able to withstand without lowering system performance when returning to the nominal pressure. inimum operating: inimum pressure at which a horizontally installed pressure cylinder operates with no-load. 4. Take into account compatibility with hydraulic fluids. ydraulic luid Standard mineral hydraulic fluid W/O hydraulic fluids O/W hydraulic fluids Water/lycol hydraulic fluids Phosphate hydraulic fluids Consult with SC. Caution Compatibility 1. Operate within the limits of the maximum usable stroke. The piston rod will be damaged if operated beyond the maximum stroke. Refer to the stroke selection on pages and 3 for maximum strokes.. Operate the piston with in a range such that collision damage will not occur at the stroke end. Operate within a range such that damage will not occur when the piston having inertial force stops by striking the cover at the stroke end. Take load factors and piston speed on page 1 into consideration and determine the operability by referring to the chart under Selection Standards. 3. Use a flow control valve to adjust the hydraulic cylinder drive speed, gradually increasing from a low speed to the desired speed setting.

30 Series CS ydraulic Cylinder Precautions e sure to read before handling. Selection 4. Provide intermediate supports for long stroke cylinders. Provide intermediate supports for cylinders with long strokes to prevent piston rod damage due to sagging of the piston rod, deflection of the tube, vibration, and external loads. Caution 1. ake sure to align the axis center of the piston with the load and direction of movement when connecting. When not properly aligned, twisting of the piston rod and tubing may occur, and damage may be caused due to wear on areas such as the inner tube surface, bushings, piston rod surface and seals. llow for decentering of the axis either by aligning the axis center or using a floating joint.. When an external guide is used, connect the piston rod end and the load in such a way that there is no interference at any point within the stroke. 3. o 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. o not use until you verify that the equipment can operate properly. ollowing mounting, repairs, or conversions, verify correct mounting by conducting suitable function and leakage tests after piping and power connections have been made. 5. Instruction manual The product should be mounted and operated after the instruction manual is thoroughly read and its contents are understood. eep the instruction manual where it can be referred to as needed. Caution ounting 1. Preparation before piping efore 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.. Wrapping of pipe tape When screwing together pipes and fittings, be certain that chips from the pipe threads and sealing material do not get inside the piping. lso, when sealant tape is used, leave 1.5 to thread ridges exposed at the end of the pipe. Expose approx. threads Piping Wrapping direction Sealant tape 3. Set up so that air cannot accumulate inside piping. Caution 1. Readjust using the cushion needle. Cushion needles are adjusted at the time of shipment. When the cylinder is put into service, the cushion needles should be readjusted based on factors such as the size of the load and the operating speed. When the cushion needles are turned clockwise, restriction of the air flow becomes greater and thus the cushioning effect also increases.. o not operate with the cushion needle in a fully closed condition. This will contribute to the generation of surge pressure, and the cylinder or equipment can be damaged. Caution Cushion ir Release 1. Operate after opening the air release valve and completely releasing any internal air. Residual air can cause a malfunction.. When adjusting the air release, do not loosen the plug too much. Use caution, since loosening the plug too much may cause it to fly out or fluid to blow out, posing a danger of human injury. Warning ydraulic luid 1. Use clean fluid. o not use deteriorated fluid or fluid containing foreign matter, moisture or corrosive additives, as this can cause the malfunction and damage or corrosion of parts. Caution 1. Install hydraulic fluid filters. Provide your hydraulic system with hydraulic fluid filters with a filtration degree of µm or finer. Refer to SC s hydraulic filter specifications.. Use the product within the specified range of fluid and ambient temperature. Take measures to prevent freezing, since moisture in hydraulic fluid will freeze at 0 C or below, and this may cause damage to seals and lead to a malfunction. 3. Use hydraulic fluid with a viscosity grade equivalent to ISO or. Operating Environment Warning 1. o not use in environments where there is a danger of corrosion. Refer to the construction drawings regarding cylinder materials.. Install a protective cover if the product is to be used in a dusty environment or where it will be exposed to chips and spatter.

31 Series CS ydraulic Cylinder Precautions 3 e sure to read before handling. Warning aintenance 1. Perform maintenance inspection according to the procedures indicated in the instruction manual. If handled improperly, malfunction and damage of machinery or equipment may occur.. Removal of equipment When machinery is removed, first ensure that there are measures in place to prevent the fall or sudden, erratic movement of driven objects and equipment. Then cut off the air supply and electric power, and reduce the pressure in the system to zero. When machinery is restarted, proceed with caution after confirming that appropriate measures are in place to prevent cylinders from sudden movement. Caution 1. Perform periodic maintenance on filters installed in a hydraulic system in order to keep the oil clean. If the oil used in hydraulic cylinders contains foreign matter, parts such as the piston seals and rod seals will be damaged.

32 Series CS uto Precautions 1 e sure to read before handling. Warning 1. Check the specifications. Read the specifications carefully and use this product appropriately. The product may be damaged or malfunction if it is used outside the range of specifications of load current, voltage, temperature or impact.. Take precautions when multiple cylinders are used close together. When two or more cylinders with auto switches are lined up in close proximity to each other, magnetic field interference may cause the switches to malfunction. aintain a minimum cylinder separation of mm. 3. onitor the length of time that a switch is ON at an intermediate stroke position. When an auto switch is placed at an intermediate position of the stroke and a load is driven at the time the piston passes, the auto switch will operate, but if the speed is too great, the operating time will be shortened and the load may not operate properly. The maximum detectable piston speed is: (mm/s) = uto switch operating range Load operating time (ms) In case of a high piston speed, it is possible to extend the operating time of the load by using an auto switch (5NT) with a built-in off delay timer (approximately 00 ms). 4. eep wiring as short as possible. <Reed switches> s the length of the wiring to a load gets longer, the rush current at switching ON becomes greater, and this may shorten the product s life. (The switch will stay ON all the time.) 1) or an auto switch without a contact protection circuit, use a contact protection box when the wire length is 5 m or longer. ) Even when an auto switch has a built-in contact protection circuit, if the lead wire length is m or more, the rush current cannot be adequately absorbed and the life of the switch may be shortened. Contact SC, as it is also necessary in this case to connect a contact protection box to extend the switch life. <Solid state switches> 3) lthough wire length should not affect switch function, use a wire that is m or shorter. 5. onitor the internal voltage drop of the switch. <Reed switches> 1) es with an indicator light If auto switches are connected in series as shown below, take note that there will be a large voltage drop because of internal resistance in the light emitting diodes. (Refer to internal voltage drop in the auto switch specifications.) [The voltage drop will be n times larger when n auto switches are connected.] Even though an auto switch operates normally, the load may not operate. Load esign and Selection 0 Similarly, when operating below a specified voltage, although an auto switch may operate normally, the load may not operate. Therefore, the formula below should be satisfied after confirming the minimum operating voltage of the load. Supply voltage Internal voltage > drop of switch ) If the internal resistance of a light emitting diode causes a problem, select a switch without an indicator light (odel - 6, -Z). <Solid state switches> 3) enerally, the internal voltage drop will be greater with a - wire solid state auto switch than with a reed switch. Take the same precautions as in 1). lso note that a C relay is not applicable. 6. onitor leakage current. <Solid state switches> With a -wire solid state auto switch, current (leakage current) flows to the load to operate the internal circuit even when in the O state. Operating current of load (O condition) > Leakage current inimum operating voltage of load If the condition given in the above formula is not met, it will not reset correctly (stays ON). Use a 3-wire switch if this specification cannot be satisfied. oreover, leakage current flow to the load will be n times larger when n auto switches are connected in parallel.. o not use a load that generates surge voltage. <Reed switches> If driving a load such as a relay that generates a surge voltage, use a switch with a built-in contact protection circuit or use a contact protection box. <Solid state switches> lthough a zener diode for surge protection is connected at the output side of a solid state auto switch, damage may still occur if the surge is applied repeatedly. When a load, such as a relay or solenoid, which generates surge is directly driven, use a type of switch with a built-in surge absorbing element.. Cautions for use in an interlock circuit When an auto switch is used for an interlock signal requiring high reliability, devise a double interlock system to avoid trouble by providing a mechanical protection function, or by also using another switch (sensor) together with the auto switch. lso perform periodic maintenance inspections and confirm proper operation.. Ensure sufficient clearance for maintenance activities. When designing an application, be sure to allow sufficient clearance for maintenance and inspections. 31
