Note) Make sure that the distance between the guide shaft center to the center of gravity of the load does not exceed the distance P between the guide shafts given in the table below. If the distance must be exceeded due to unavoidable circumstances, decrease the load rate that is applied to the guide as indicated below in order to determine the distance.

In conditions in which the load mass and the speed will be above the curve, use a shock absorber (provided that the maximum load mass is not exceeded). Caution In the case of the ball bushing type, the service life could be drastically shortened if shocks or excessive moments are applied. Therefore, even if the conditions given above are not exceeded, the use of a shock absorber is recommended.

Series Specific Product Precautions e sure to read before handling. Refer to front matters 4 and 43 for Safety Instructions and pages 3 to for ctuator and uto Switch Precautions. Caution Operating Precautions. Make sure not to apply to the slide block a load that exceeds the value that has been calculated in the selection procedures.. Operate the cylinder securing it by its plates, not by securing it by its slide block. 3. The clearance between the slide block and the plate at the stroke end is approximately mm to mm. It could be extremely dangerous, as there is the risk of getting your fingers caught. Install a cover as necessary. 4. t both stroke ends, adjust the damper portion at the end of the adjusting bolt so that it comes in contact with the slide block. (The clearance between the slide block and the plate must be mm or more.) If it is operated without making any contact, the piston rod of the actuating cylinder or the connecting hardware (adapter) could become damaged by an excessive impact, or the slide block could collide with the plate and create an abnormal noise.. The load mass or operating speed will be limited if only the adjusting bolt is used. Refer to the section on llowable load when only the adjusting bolt is used on page 3. Please contact SMC if this product will be used in an environment in which the piston rod and the guide shaft surfaces will be exposed to water (hot water), coolant, cutting chips, or dust. 7. The slide block bearings must be greased periodically. Inject grease (Class or lithium soap grease consistency) through the grease inlet. Note) On those with a cylinder bore of ø, apply grease to the guide shaft. 8. To operate the cylinder, use a non-lubricating air supply. Use turbine oil Class (ISO V), if lubricated. (Using machine oil or spindle oil are not allowed.) Caution Mounting. hile a high level of flatness is desired for the surface on which the cylinder is to be mounted, if sufficient flatness cannot be attained, use shims to adjust the installation of the cylinder so that the slide block can operate throughout its stroke under the minimum operating pressure.. Do not scratch or gouge the piston rod of the actuating cylinder, as this could damage the rod seal and lead to air leaks. The same applies to the guide shaft. 3. Make sure not to apply shocks or excessive moment to the slide block of the ball bushing type. 4. The port direction of the actuating cylinder can be changed in 0 increments by removing the four bolts that secure the cylinder in place. fter changing the direction, verify the operation at the minimum operating pressure.. efore the installation, thoroughly flush out the piping to prevent dust or cutting chips from entering the cylinder.. The mounting position of the adjusting bolt and the shock absorber cannot be inverted due to the constraints imposed by the locating pin for the shock absorber that is provided on the slide block. To invert the position, please contact SMC. Handling on Shock bsorber Caution. Series R (SMC made) shock absorbers can absorb a wide range of energy without requiring adjustment. (No adjustment screw is provided.). The screw at the bottom is not for adjustment. Never turn this screw as it could cause an oil leak (lowered performance). 3. Do not scratch the surface of the shock absorber rod because doing so could affect the shock absorber s durability or lead to poor retraction. For detailed specifications about the shock absorber, refer to page 73. Service Life and Replacement Period of Shock bsorber Caution.llowable operating cycle under the specifications set in this catalog is shown below.. million cycles R08 million cycles R to R7 Note) Specified service life (suitable replacement period) is the value at room temperature ( to C). The period may vary depending on the temperature and other conditions. In some cases the absorber may need to be replaced before the allowable operating cycle above. CX CX J 33
