3 Selection Series How to Find σ when Selecting the llowable Load Mass Caution on Design (1) Examples of llowable Load Mass Calculation Based on Cylinder Mounting Orientation Since the maximum load mass with respect to the cylinder stroke changes as shown in the table below, σ should be considered as a coefficient determined in accordance with each stroke. Example) -50 (1) Maximum load mass = kg (2) Load mass for 50 st = 1. kg 1. () σ = = 0.8 is the result. 1.

11 Series Specific Product Precautions Be sure to read this before handling the products. Refer to back page 50 for Safety Instructions and pages to 12 for ctuator and uto Switch Precautions. arning Caution Operation 1. Be aware of the space between the plates and the slide block. Take sufficient care to avoid getting your hands or fingers caught when the cylinder is operated. 2. Do not apply a load to a cylinder which is greater than the allowable value stated in the Selection pages. This may cause malfunctions.. Do not use the cylinder in an environment where the cylinder is expose to moisture, adhesive foreign matter, dust or liquid such as water or cutting fluid. If the cylinder is used in an environment where the lubrication of the cylinders sliding parts is compromised, please consult SMC. 4. hen applying grease to the cylinder, use the grease that has already been applied to the product. Contact SMC for available grease packs. Mounting 1. void operation with the external slider fixed to the mounting surface. The cylinder should be operated with the plates fixed to the mounting surface. 2. Make sure that the cylinder mounting surface is a flatness of 0.2 mm or less. If the flatness of the cylinder mounting surface is not appropriate, 2 guide shafts may be twisted. This may adversely affect the operating conditions and shorten the service life due to the increase of sliding resistance and the early abrasion of bearings. The cylinder mounting surface must be a flatness of 0.2 mm or less, and the cylinder must be mounted as it smoothly operates through the full stroke at the minimum operating pressure (0.18 MPa or less). Service Life and Replacement Period of Shock bsorber Caution 1. llowable operating cycle under the specifications set in this catalog is shown below. 1.2 million times RB08 2 million times RB to RB27 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. Disassembly and Maintenance arning 1. Use caution as the attractive power of the magnets is very strong. hen 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 a very strong attractive force. Caution 1. Use caution when removing the external slider, as the piston slider will be directly attracted to it. hen 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 when there is no longer any holding force. If they are removed while still magnetically coupled, they will be directly attracted to one another and will not come apart. 2. Since the magnetic holding force can be changed (for example, from L to H), please contact SMC if this is necessary.. Do not disassemble the magnetic components (piston slider, external slider). This can cause a loss of holding force and malfunction. 4. hen disassembling to replace the seals and wear ring, refer to the separate disassembly instructions. 5. Use caution to the direction of the external slider and the piston slider. Since the external slider and piston slider are directional for ø, ø and holding force type L, 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 Fig. (1). If they align as shown in Fig. (2), insert the piston slider after turning it around 180. If the direction is not correct, it will be impossible to obtain the specified holding force.

25 t Series Specific Product Precautions 1 Be sure to read this before handling the products. Refer to back page 50 for Safety Instructions and pages to 12 for ctuator and uto Switch Precautions. arning Caution Operation 1. Be aware of the space between the plates and the slide block. Take sufficient care to avoid getting your hands or fingers caught when the cylinder is operated. 2. Do not apply a load to a cylinder which is greater than the allowable value stated in the Selection pages. This may cause malfunctions.. hen the cylinder is used in a place where water or cutting oil may splash or the lubrication condition on the cylinder sliding parts would be deteriorated, please consult with SMC. 4. hen applying grease to the cylinder, use the grease that has already been applied to the product. Contact SMC for available grease packs. 1. The unit can be used with a direct load within the allowable range, but when connecting to a load which has an external guide mechanism, careful alignment is necessary. Since variation of the shaft center increases as the stroke becomes longer, a connection method should be devised which allows for this displacement. 2. Since the guide is adjusted at the time of shipment, unintentional movement of the adjustment setting should be avoided.. This unit can be operated without lubrication. If lubrication is performed, use turbine oil Class 1 (with no additives), ISO VG. (Machine oil and spindle oil cannot be used.) 4. Do not use the cylinder in an environment where the cylinder is expose to moisture, adhesive foreign matter, dust or liquid such as water or cutting fluid. If the cylinder is used in an environment where the lubrication of the cylinders sliding parts is compromised, please consult SMC. 5. 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).. Do not disassemble the magnetic components (piston slider, external slider). This can cause a loss of holding power and malfunction. Caution Thread size M4 x 0.7 Bolt dimensions Dimension t L-7 Tightening torque N m Mounting 1. The interior is protected to a certain extent by the top cover, however, when performing maintenance, etc., take care not to cause scratches or other damage to the cylinder tube, slide table or linear guide by striking them or placing objects on them. Cylinder bores are manufactured to precise tolerances, so that even a slight deformation may cause faulty operation. 2. Because the slider is supported by precision bearings, take care not to apply strong impacts or excessive moments to the table when loading a workpiece.. Mounting of the cylinder body The body is mounted using the square nuts, which are included, in the two T-slots on the bottom of the body. Refer to the table below for mounting bolt dimensions and tightening torque. T T 1.7 L-8 M5 x L-8 Square nut M x 1.0 L L M8 x 1.

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.

26 Series Specific Product Precautions 2 Be sure to read this before handling the products. Refer to back page 50 for Safety Instructions and pages to 12 for ctuator and uto Switch Precautions. Stroke djustment Method Loosen the round head Phillips Screws, and remove the top cover and dust covers (4 pcs.). Round head Phillips screw Hexagon nut Shock absorber Top cover Dust cover Hexagon nut djusting bolt Loosen the hexagon nut, adjust the stroke with a hexagon wrench from the plate side, and secure by retightening the hexagon nut. hen there is a shock absorber, loosenthe hexagon nut, adjust the stroke, and then retighten the hexagon nut. djustment should be performed to make effective use of the shock absorber s absorption capacity, with its position relative to the adjustment bolt as shown in the figure to the right. Caution 1. If the effective stroke of the shock absorber is shortened by the stroke adjustment, its absorption capacity will be drastically reduced. Therefore, the adjusting bolt should be secured at a position where it projects about 0.5 mm farther than the shock absorber. Lock Nut Tightening Torque N m For shock absorber For adjusting bolt T.14 T 2.5 Shock absorber 0.5 djusting bolt fter completing the above adjustment, replace the top cover and dust covers back into place.
