1 U SM Series WRNING This product must not be used submerged in water, oil or powder, or where coolant, coolant fluid or swarf, etc., may come in contact. lways incorporate an interlock in the control circuit for carrier movement to ensure safety. pplications in which the carrier is fixed and the rail section is used as the moving object are not possible. Make sure that the cylinder tube and rail will not be damaged by accidentally dropping workpieces. Not doing so could cause malfunctions. CUTION Confirm that the sectional area of the pipe connecting the cylinder and direction control valve is adequate for achieving the specified piston speed. WRNING Pneumatic components Safety precautions lways read this section before starting use. Refer to Intro 7 for general precautions of the cylinder, and to Intro 78 for general precautions of the cylinder switch. If this product intersects passageways or workers work areas, always provide a safety cover at areas where a human hand can enter as protection from movement areas and dropping. Do not move this product by hitting it with a hammer, or directly suspend it with a wire rope, etc. Immediately after installing this product (before supplying the air) directly move the carrier by hand and check for interfering objects in the movement area. The stroke end is adjusted 0mm by sliding the entire end block. If adjusted by the amount that the stopper bolt and shock absorber are screwed in, the magnetic connection of the carrier and piston will deviate. Design & Selection Installation & djustment The leg installation pitch should be an interval of two meters. Provide the following space near the end unit. Sufficient space to remove the workpiece Sufficient space to adjust the carrier stroke end 0mm Sufficient space to move when adjusting the tube piping connected to the end piping connection port 0mm, and space to adjust the speed controller Sufficient space to remove the end rail related parts when servicing the piston CUTION The connection port block is slid to adjust the stroke end by 0mm. Use nylon or urethane tubing for this connection, and provide sufficient allowance in the length. 2 x 8mm tube should be used. If the rail is twisted, bent or pulled when the legs are installed, air could leak from the joint section. Do not apply excessive force. Make sure that foreign matter such as drill chips generated during the installation do not enter the cylinder tube during installation and assembly. 228

2 Series WRNING The most suitable ambient temperature range for using the cylinder is 5 to 40 C. void use at temperatures exceeding 40 C as damage or operation faults, etc., could result. If the temperature drops below 5 C, the water in the circuit could freeze and cause damage or operation faults, so always provide means to prevent freezing. The shuttle mover is a magnetic rod-less cylinder. magnetic is incorporated, so keep away products affected by magnets (magnetic disks, magnetic cards, magnetic tape, testers, etc.). The magnetic connection of the carrier and piston could deviate if an external force exceeding the magnetic holding force is applied. Operation faults could result if foreign matter gets caught between the carrier and rail. Grease is applied inside the cylinder tube. Make sure that foreign matter such as swarf does not get in during assembly or disassembly work. During Use & Maintenance CUTION If the oil is spent and operation becomes unstable, remove the piston and grease it. Refer to the instruction manual for details on greasing. The periodic greasing should be carried out after 2,000km of travel. When using in a place where the rail, etc., could become dirty, the cylinder must be periodically cleaned to improve the guide roller rotation. U Rodless type 229

20 Series U Q Q Q Q Q uestion Can the carrier be braked? & Design Braking is not possible. What is the 's air consumption rate? nswer The rate is the same as a typical 25 bore size cylinder. When estimating the transfer time, what rate (m/s) should be used for the speed? (When estimating in consideration of the various conditions including rail combination, difference in load weight, deceleration time or working pressure, etc.) Estimate at m/s. (Example: t a 20m stroke, 20m m/s = 20s. The workpiece's loading time is not included in this time.) Does the maximum allowable load rate refer to the workpiece's weight? This is the weight of the total load put on the carrier. The hand chuck and Z axis cylinder are included in this value. 2238

21 Q Q Q Q Q Q Q Is a safety cover required? Safety Maintenance Series Q& lways install a cover since this joint type air cylinder may be used for overhead travel at a high speed. What happens if the carrier is not decelerated at the stroke end? (t 0.5m/s or more) Can the carrier's roller be replaced? Dedicated tools are required, so contact CKD for overhaul (paid-for-service). Do the carrier rollers need to be oiled? Electric Control Is there a carrier detection lead switch? The shock absorber could be damaged. lways provide a deceleration circuit such as a shock-less valve (SKH Series). Shielded metal bearings with urethane rubber are used, so the carrier rollers can be used in a non-oiled state. How can the stroke be adjusted? The stroke can be adjusted 0mm forward or 0mm backward at the rail end. Refer to the instruction manual for details on adjusting the stroke. There is no lead switch. Use a proximity sensor, photo electric sensor or a photo sensor. How should the electrical signals for the actuator mounted on the carrier be output? The signals cannot be output as there is no electricity supply to the operation confirmation lead switch, etc. U Rodless type 2239
