Series / Precautions on Design Selection Procedure Selection procedure. Find the drive resisting force Fn (N) when moving the load horizontally.. Find the distance Lo (cm) from the point of the load where driving force is applied, to the center of the cylinder shaft. 3. Select the bore size from Lo and Fn, based on data A. Discrepancy absorption mechanism Workpiece Load Fn Lo Selection example Given a load drive resisting force of Fn = 0 (N) and a distance from the cylinder shaft center to the load application point of Lo = cm, find the intersection point by extending upward from the horizontal axis of data A where the distance from the shaft center is cm, and then extending to the side, find the allowable driving force on the vertical axis. Models suitable in satisfying the requirement of 0 (N) are CY3 or CY3. The Lo point from the cylinder shaft center is the moment working point between the cylinder and the load section. <Data A : Distance from cylinder shaft center 0 3 4 0 3 4 0 3 4 0 0 0 3 4 3 0 0 0 0 0 3 4 3 0 0 0 0 0 3 4 3 4 0 0 0 0 0 3 4 3 4 00 0 0 0 0 0 3 4 3 4 3 00 0 0 0 0 0 Allowable driving capacity> 0 3 4 3 4 44

Series / Cylinder Dead Weight Deflection Precautions on Design Maximum Weight of Connection Bracket to the Body When the cylinder is mounted horizontally, deflection appears due to its own weight as shown in the data, and the longer the stroke is, the greater the amount of variation in the shaft center. Therefore, a connection method should be considered which can assimilate this deflection. Guide shaft Load platform Vertical Operation Clearance (Note) (0. to 0. mm) CY3 4 3 4 3,, CY3 CY3 CY3,3 CY33 CY3 CY3 CY3 CY CY3 It is recommended that the load is guided by a ball type bearing (linear guide, etc.). If a slide bearing is used, sliding resistance increases due to the load mass and moment, which may cause malfunctions. When the cylinder is mounted vertically or sidelong, a slider may move downwards due to the selfweight or workpiece mass. If an accurate stopping position is required at the stroke end or midstroke, use an external stopper to secure accurate positioning. W Rodless cylinder Load mass (Slider bracket weight + Workpiece mass) Workpiece C (Note) The above clearance amount is a reference value. Note ) According to the dead weight deflection in the figure on the right, provide clearance so that the cylinder does not touch the mounting surface or the load, etc., and is able to operate smoothly within the minimum operating pressure range for a full stroke. For more information, refer to instruction manual. Note ) In case of the, install a shim, etc. to eliminate clearance between the body and the switch rail. For more information, refer to the instruction manual. Note 3) The amount of deflection differs from the CYB/CYR. Adjust the clearance value by referring to the dead weight deflection as shown in the table on the right. When CYB/CYR are replaced with /, install a cylinder after confirming a full stroke and clearance are allowed.

Series / Specific Product Precautions Be sure to read before handling. Refer to front matter for Safety Instructions and pages 3 to for Actuator and Auto Switch Precautions. Warning Caution Handling. Pay attention to the space between the head cover and the body. Take sufficient care to avoid getting your hands or fingers caught when the cylinder is operated.. Do not apply a load to a cylinder which is greater than the allowable value stated in the Model Selection. Applying an improper load may cause malfunctions. 3. When the cylinder is used in a place where water or cutting oil may splash it or the lubrication on its sliding parts could be deteriorate, please consult with SMC. 4. When applying grease to the cylinder, use the grease that has already been applied to the product. Contact SMC for available grease packs. Mounting. Take care to avoid nicks or other damage on the outside surface of the cylinder tube. This can lead to damage of the wear ring and lubretainer, which in turn can cause malfunction.. Take care regarding rotation of the external slider. Even when the rotation is controlled by connecting the external slider to other shaft (linear guide, etc.), keep it in the floating connection status. 3. Do not operate with the magnetic coupling out of position. In case the magnetic coupling is out of position, push the external slider back into the correct position by hand at the end of the stroke (or correct the piston slider with air pressure). 4. The cylinder is mounted with bolts through the mounting holes in the end covers. Be sure they are tightened securely. (). If gaps occur between the mounting surface and the end covers when mounting with bolts, perform shim adjustment using spacers, etc. so that there is no unreasonable stress. (). Be sure that both end covers are secured to the mounting surface before operating the cylinder. Avoid operation with the external slider secured to the surface. Guide rod Caution Mounting. Do not apply a lateral load to the external slider. When a load is mounted directly to the cylinder, variations in the alignment of each shaft center cannot be assimilated, which results in the generation of a lateral load that can cause malfunction. (Figure ) The cylinder should be operated using a connection method which allows for assimilation of shaft alignment variations and deflection due to the cylinder's own weight. A drawing of a recommended mounting is shown in Figure. Direct connection with bolts, etc. Mounting bracket Guide rod Center of axis Shock absorber Rodless cylinder Rodless cylinder Stopper Variations in the load and cylinder shaft alignment cannot be assimilated, resulting in malfunction. Shaft alignment variations are assimilated by providing clearance for the mounting bracket and cylinder. Moreover, the mounting bracket is extended above the cylinder shaft center, so that the cylinder is not subjected to moment. Figure. Incorrect mounting Figure. Recommended mounting Note) The drawing shows the series.. Use caution regarding the allowable load mass when operating in a vertical direction. The allowable load mass when operating in a vertical direction (reference values on page 4) is determined by the model selection method, however, if a load greater than the allowable value is applied, the magnetic coupling may break and there is a possibility of dropping the load. When using this type of application, contact SMC regarding the operating conditions (pressure, load, speed, stroke, frequency, etc.).. Careful alignment is necessary when connecting to a load having an external guide mechanism. As the stroke becomes longer, variations in the center axis become larger. Consider using a connection method (floating mechamism) that is able to absorb these variations. Furthermore, use the special floating brackets (XC) which have been provided for the and series (page ). CYS -Z CYL CYH CYF CYP 4 D- -X Technical data
Series / Specific Product Precautions Be sure to read before handling. Refer to front matter for Safety Instructions and pages 3 to for Actuator and Auto Switch Precautions. Disassembly & Maintenance Warning. Use caution as the attractive power of the magnets is very strong. When removing the external slider and piston slider from the cylinder tube for maintenance, etc., handle with caution, since the magnets installed in each slider have very strong attractive power. Caution. When reattaching the head covers after disassembly, confirm that they are tightened securely. () When disassembling, hold the wrench flat section of one head cover with a vise, and remove the other cover using a spanner or adjustable angle wrench on its wrench flat section. When retightening, first coat with Locktight (No. 4 red), and retighten 3 to past the original position prior to removal.. Special tools are necessary for disassembly. () Disassembly & Maintenance Caution. Note the direction of the external slider and piston slider. Since the external slider and piston slider are directional for ø and ø, refer to the figures below when performing disassembly or maintenance. Put the external slider and piston slider together, and insert the piston slider into the cylinder tube so that they will have the correct positional relationship as shown in Figure 3. If they align as shown in Figure 4, insert the piston slider after turning it around 0. If the direction is not correct, it will be impossible to obtain the specified holding force. Figure 3. Correct position Figure 4. Incorrect position For ø and ø F Special Tool Number List Part no. CYRZ-V CYRZ-W CYRZ-X CYRZ-Y Special tool Applicable bore size,,,,, 3 3. Use caution when taking off the external slider, as the piston slider will be directly attracted to it. When removing the external slider or piston slider from the cylinder tube, first force the sliders out of their magnetically coupled positions and then remove them individually while there is no longer any holding force. If they are removed when still magnetically coupled, they will be directly attracted to one another and will not come apart. 4. Do not disassemble the magnetic components (piston slider, external slider). This can cause a loss of holding force and malfunction.. When disassembling to replace the seals and wear ring, refer to the separate disassembly instructions. 4
