Two types of guide rod bearings to accommodate your application For heavy loads all bushing bearing For highly accurate and smooth operation uto switch can be mounted. shock absorber can be installed (option). Can be mounted on two sides. Mounting from the upper side Mounting from the bottom side djusting bolt with bumper is standard. Performs the function of a cushion and adjusts the stroke mm on each side, or mm for both sides. For moving and transferring workpieces. Series Variations Slide bearing M M M earing type all bushing bearing For moving the receptacle for workpieces used in stamping or press-fitting processes.

The moment for the inclined mounting must be calculated taking the moment caused by the load into consideration. Note) Make sure that the distance between the guide shaft center to the center of gravity of the load does not exceed the distance GP 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. 1 Σαn (/GP) (Provided that > GP) β > 0.

In conditions in which the load weight and the speed will be above the curve, use a shock absorber (provided that the maximum load weight 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. oad weight (kg) Speed (mm/s) Static Movable Mass when Stopped hen the series cylinder is used for moving the workpiece receptacle, such as in a stamping or press-fitting process, a vertical load will be applied to the top surface of the stopped slide block (refer to the figure on the right). In this case, the allowable mass is greater than the maximum load weight, as given in the table on the right. Caution 1. Make sure that the slide block is stopped at the stroke end.. Match the center of the mass to be applied with the center of the slide block. The direction of the mass must be vertically downward in relation to the surface on which the workpiece is mounted, as shown in the figure on the right. 3. Do not apply a load that involves shocks such as those caused by pounding (particularly with the ball bushing type). 4. If this mass is applied, the deflection of the guide shaft will also have a large value. llowable Static Mass (kg) M () (all bushing bearing) CX CX CXSJ CXS D- -X

14 Series Specific Product Precautions e sure to read this before handling the products. Refer to back page 0 for Safety Instructions and pages 3 to for ctuator and uto Switch Precautions. Caution Operating Precautions 1. 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 1 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 1 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 weight or operating speed will be limited if only the adjusting bolt is used. Refer to the section on llowable load when only the adjustment bolt is used on page 711. 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 1 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 1 (ISO VG), if lubricated. (Using machine oil or spindle oil are not allowed.) Caution Mounting 1. 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 90 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 1. The R series (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 est Pneumatics No. -3. Service ife and Replacement Period of Shock bsorber Caution 1.llowable operating cycle under the specifications set in this catalog is shown below. 1. 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. 7
