4 Series REA/REB Specific Product Precautions Be sure to read before handling. 4 Disassembly and Maintenance arning. Use caution as the attractive force 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. 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. Do not disassemble the magnetic components (piston slider, external slider). This can cause a loss of holding force and malfunction. 3. hen disassembling to replace the seals and wear ring, refer to the separate disassembly instructions. 4. Use caution to the direction of the external slider and the piston slider. Since the external slider and piston slider are directional for size 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 Fig. (). If they align as shown in Fig. (2), reinsert the piston slider only, after turning it around 80. If the direction is not correct, it will be impossible to obtain the specified holding force. Fig. () Correct position Fig. (2) Incorrect position. During disassembly, use caution in handling the cushion ring. The cushion ring is a precision part, and any deformation, etc., can cause malfunction or poor performance. Caution. SMC s throttle type speed controllers (Series AS) are recommended for speed adjustment. (Refer to Table ().) 2. Speed adjustment is possible with meter-in/meter-out type speed controllers, but it may not be possible to obtain the cushion effect (smooth start-up, soft stop). 3. In the case of other than horizontal mounting, it is recommended that the system have a reduced pressure supply circuit installed at its lower side. (This is also effective as a countermeasure against start-up delay on an upward stroke, and for air conservation.)

6 Sine Rodless Cylinder Basic Type Series REA Precautions Be sure to read before handling. Refer to pages to -24- for Safety Instructions and Actuator Precautions. Caution Mounting. Take care to avoid nicks or other damage on the outside surface of the cylinder tube. This can lead to a damage of the scraper and the wear ring, which in turn can cause malfunction. 2. Use caution to the rotation of the external slider. Rotation should be controlled by connecting it to another shaft (linear guide, etc.). 3. Do not operate with the magnetic coupling out of position. If the magnetic coupling is out of position, push the external slider by hand (or the piston slider with air pressure) back to the proper position at the stroke end. 4. Be sure that both head covers are secured to the mounting surface before operating the cylinder. Avoid operation with the external slider secured to the surface.. Do not apply a lateral load to the external slider. hen a load is mounted directly to the cylinder, variations in the alignment of each shaft center cannot be offset, which results in the generation of a lateral load that can cause malfunction. The cylinder should be operated using a connection method which allows for shaft alignment variations and deflection due to the cylinder's own weight. A drawing of a recommended mounting is shown in Fig. (2). Guide rod Rodless cylinder Direct connection with bolts, etc. Variations in the load and cylinder shaft alignment cannot be offset and may result in a malfunction. Fig. () Incorrect mounting Mounting bracket Guide rod Rodless cylinder Stopper Shaft alignment variations are offset by providing clearance between 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. Fig. (2) Recommended mounting. Use caution regarding the allowable load weight when operating in a vertical direction. The allowable load weight when operating in a vertical direction (reference values on page -2- is determined by the model selection method. owever, if a load greater than the allowable value is applied, the magnetic coupling may break and there is a possibility of dropping the load. hen using this type of application, please contact SMC regarding the operating conditions (pressure, load, speed, stroke, frequency, etc.). Disassembly and Maintenance Caution. hen reattaching the head covers after disassembly, confirm that they are tightened securely. hen disassembling, hold the wrench flats of one head cover with a vise, and remove the other cover using a spanner or adjustable wrench on the wrench flats. hen retightening, first coat with Loctite (no. 42 Red), and retighten 3 to past the original position prior to removal. Caution. This mechanism is not intended for adjustment of the cushion effect (smooth start-up, soft stop). This mechanism is for matching of the cylinder's stroke end position to the mechanical stopper, etc., of a machine. (adjustment range from 0 to 2 mm) 2.

Further, the exhaust air in the right chamber of the drive piston passes from inside the hollow cushion ring through the cylinder port and is released to the atmosphere by the drive solenoid valve. hen the differential pressure (thrust) generated on either side of the drive piston becomes larger than the starting resistance of the machinery, the drive piston begins to move to the right. As the drive piston moves to the right, the U-shaped groove in the outer surface of the cushion ring gradually becomes deeper, a flow corresponding to the drive speed of the drive piston flows into the left chamber of the drive piston, and the drive piston proceeds to accelerate. The U-shaped groove is machined into the cushion ring in such a way that this acceleration process can proceed smoothly (as a sine function). Deceleration/Stop In conventional cushion mechanisms, when the cushion seal installed on the drive piston is pushed into the cushion ring at the right stroke end, the drive piston's right chamber is pressurized and a sudden braking force is generated. owever, in a sine rodless cylinder, due to the U-shaped groove provided on the outer surface of the cushion ring, whose depth changes as a sine function, a large quantity of the air in the cushion chamber is discharged when the cushion seal is pushed in, and a sudden braking force is not generated. ith the progression of the cushion stroke, the discharge flow from the cushion chamber is restricted, and therefore, a soft stop is achieved at the stroke end.

49 Series REA 49 Precautions Be sure to read before handling. Refer to pages to -24- for Safety Instructions and Actuator Precautions. Caution Mounting. 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. 3. 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. REA REA REA REA REAT REAT Bolt Thread size M4 x 0.7 M x 0.8 M x.0 M8 x. dimensions Tightening torque Dimension t N m l-7.37 l-8 2. l l Caution Operation. 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. 3. Please contact SMC before operating in an environment where there will be contact with cutting chips, dust (paper debris, lint, etc.) or cutting oil (gas oil, water, warm water, etc.). 4. 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).

64 Sine Rodless Cylinder Direct Mount Type Series REBR 4 Precautions Be sure to read before handling. Refer to pages to -24- for safety instructions and Actuator Precautions.. Take care to avoid nicks or other damage on the outside surface of the cylinder tube. This can lead to a damage of the scraper and the wear ring, which in turn can cause malfunction. 2. Use caution to the rotation of the external slider. Rotation should be controlled by connecting it to another shaft (linear guide, etc.). 3. Do not operate with the magnetic coupling out of position. If the magnetic coupling is out of position, push the external slider by hand (or the piston slider with air pressure) back to the proper position at the stroke end. 4. The cylinder is mounted with bolts through the mounting holes in the end covers. Be sure they are tightened securely.. 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.. Do not apply a lateral load to the external slider. hen a load is mounted directly to the cylinder, variations in the alignment of each shaft center cannot be offset, which results in the generation of a lateral load that can cause malfunction. The cylinder should be operated using a connection method which allows for shaft alignment variations and deflection due to the cylinder's own weight. A drawing of a recommended mounting is shown in Fig. (2). Guide rod Caution Rodless cylinder Direct connection with bolts, etc. Variations in the load and cylinder shaft alignment cannot be offset and may result in a malfunction. Fig. () Incorrect mounting Mounting Mounting bracket Guide rod Clearance Rodless cylinder Shaft alignment variations are offset by providing clearance between 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. Fig. (2) Recommended mounting 7. Use caution regarding the allowable load weight when operating in a vertical direction. The allowable load weight when operating in a vertical direction (reference values on page -2-8) is determined by the model selection method. owever, if a load greater than the allowable value is applied, the magnetic coupling may break and there is a possibility of dropping the load. hen using this type of application, please contact SMC regarding the operating conditions (pressure, load, speed, stroke, frequency, etc.)..

Therefore, a connection method should be considered which allows for this variation as shown in the drawing. Guide shaft Load platform Caution on Design 2 Vertical Operation The load should be guided by a ball type bearing (LM guide, etc.). If a slide bearing is used, sliding resistance will increase due to the load weight and moment, and this can cause malfunction.
