BK-UC003 Ver.1.0 Air Cylinder Z SLIDER INSTRUCTION MANUAL Ver.1.0 Handling Instructions and Precautions Selection, installation, stroke adjustment, and piping Selection Piping location and operating direction 1. Use “Sizing Guide” on p.944 to select the load so that maximum load, allowable moment, and operating speed, etc., do not exceed the specifications limit. Maintaining values at about 80% of the allowable range is recommended. This level will constrain detrimental effects on the cylinder and guide to a minimum. 2. If using an external stopper to perform an intermediate stop, take precautions to prevent the unit from popping up due to the control circuit or external control method. Popping up can result in damage to equipment. The plate and table move Retracted Extended side to the extended side side when air is supplied to the B or C connection ports, and to the retracted side when air is supplied to the A or D A connection ports. Note that, at shipping, the C and D connection ports B are plugged. Mounting 1. While any mounting direction is allowed, the mounting surface should always be flat. Twisting or bending during mounting may disturb the accuracy and may also result in air leaks or improper operation. 2. Caution should be exercised that scratches or dents on the Z slider’s mounting surface may damage its flatness. 3. In applications subject to large shocks, reinforce the bolt mounting, by installing a support to the Z Slider body, for example, is recommended. 4. Do not leave scratches or dents in the areas where the piston rod contacts. It could result in damage to the seals or in air leaks. 5. In cases where the mounting bolts and nuts for the body, stroke adjusting bracket, or workpiece could become loosened by shocks or vibrations, take measures to prevent loosening. For the recommended tightening torque and the sizes of the various bolts and nuts, see the table below. ● Recommended tightening torques of the mounting bolts and nuts for the body, stroke adjusting bracket, and workpiece Bolt size Recommended tightening torque Nut size Recommended tightening torque M3×0.5 1.18 [0.87] M 6×0.75 0.85 [0.63] M4×0.7 1.37 [1.01] M 8×0.75 2.45 [1.81] M5×0.8 2.84 [2.09] M10×1.0 6.37 [4.70] M6×1.0 4.80 [3.54] M12×1.0 11.77 [8.68] M8×1.25 12.0 [8.85] ― ― N・m [ft・lbf] N・m [ft・lbf] ● Size for the mounting bolts and nuts for the body, stroke adjusting bracket, and workpiece Bore size For mounting body Female thread For securing stroke adjustment For Rubber mounting Bracket A and B stopper and workpieces Stopper B Stopper A shock mm [in.] Through hole φ6 [0.236] M3×0.5 M4×0.7 M4×0.7 M3×0.5 M3×0.5 M 6×0.75 φ10 [0.394] M3×0.5 M4×0.7 M4×0.7 M3×0.5 M4×0.7 M 8×0.75 φ16 [0.630] M4×0.7 M5×0.8 M5×0.8 M4×0.7 M4×0.7 M10×1.0 φ20 [0.787] M5×0.8 M6×1.0 M6×1.0 M5×0.8 M5×0.8 M12×1.0 φ25 [0.984] M6×1.0 M8×1.25 M8×1.25 M6×1.0 M6×1.0 M12×1.0 absorber Stroke adjustment The optional stroke adjusting bracket set is available with either the rubber stopper type or shock absorber type. In both types, stroke adjustment within the range shown on p.949 is easy for both the extended and retracted sides (for end keep type, extended side only). For both the extended and retracted sides, rotating the stroke adjusting stopper bolt or shock absorber to the right (clockwise) shortens the stroke. After adjustment, tighten the lock nut to secure it in place. Note that the rubber stopper or shock absorber are included at shipping but not assembled. D C Control circuit for the end keep cylinder 1. For control of the Z Slider with End Keep, we recommend the use of 2-position, 4-, 5-port valves. Avoid the use of control circuit with ABR connection (exhaust centers) 3-position valves that exhaust air from 2 delivery ports. 2. Always use meter-out control for speed control. Meter-in control may result in failure of the locking mechanism to release. 3. Always set the air pressure to 0.2MPa [29psi.] or more. Cautions: 1. It is dangerous to supply air to a connection port on a side with a locking mechanism while the cylinder has already been exhausted, because the piston rod may suddenly extend, etc. In addition, since the lock piston could also cause galling of the lock piston and piston rod, resulting in defective operation. Always supply air to the connection port opposite the one adjacent to the locking mechanism to ensure applying back pressure. 2. When restarting operations after air has been exhausted from the cylinder due to completion of operations or to an emergency stop, always start by supplying air to a connection port opposite the one adjacent to the locking mechanism. 3. Connect the valve port A (NC) to the connection port on the side with the locking mechanism. Manual operation of locking mechanism While the locking mechanism is normally released automatically through cylinder operations, it can also be released manually. For manual release, insert an M3×0.5 screw that has 30mm [1.18in.] screw length into the opening for the manual override, thread it in about 3 turns into the internal lock piston, and then pull up the screw. To maintain the manual override for adjustment, etc., thread the locknut onto the screw, and with the locking mechanism in a released state, tighten the locknut against the cylinder. Pull out M3×0.5 screw Lock nut Cautions: 1. It is dangerous to release the lock when load (weight) is present on the piston rod, because it may cause the unintended piston rod’s extension, etc. In this case, always supply air to the connection port opposite the one adjacent to the locking mechanism before releasing the locking mechanism. 2. If the locking mechanism cannot easily be released even with manual override, it could be the result of galling of the lock piston and piston rod. In this case, supply air to the connection port opposite the one adjacent to the locking mechanism before releasing the locking mechanism. 3. Water, oil, dust, etc., intruding through the opening for the manual override may cause defective lock or other erratic operation. If using in locations subject to dripping water, dripping oil, etc., or large amounts of dust, use a cover to protect the unit. Handling Instructions and Precautions With buffer ●Spring return force (with buffer) Operating conditions 1. For applications with buffer type, use and place the buffer mechanism side in the down side in vertical installation, or horizontal installation. Because the cylinder buffer may operate even at the buffer’s full-stroke conditions depending on the load and/or speed, adjust the load and speed to avoid it in the case. 2. Do not operate the buffer mechanism while it is on the retracted side. 3. Do not apply external force on the sub-plate in the direction from the table surface to the bottom of the body, either after completion of the stroke or during the stroke movement. Spring return force The spring return force incorporated into the plate with buffer can be adjusted in 4 levels. The return force at shipping is set to the lowest level (at Level 1), with the snap ring on the plate front surface retained in the closest groove to the front. To change the return force, squeeze the snap ring and move it together with the washer to the groove position for giving the desired return force, then use the snap ring to secure the washer and spring into place. When squeezing the snap ring, take caution that the washer or snap ring do not pop out due to the spring return force. In addition, be careful to avoid over-squeezing the snap ring. It could lead to damage the ring. After adjusting the spring force, check that the snap ring is secured in the position.

Frequently asked questions
The maximum allowable load mass for a ZS16 Z-slider is 22.921 kg [50.54 lb.]. This information can be found in Table 1 of the Sizing Guide section of the manual.
You can adjust the spring return force in 4 levels. The return force at shipping is set to the lowest level (at Level 1). To change the return force, squeeze the snap ring and move it together with the washer to the groove position for giving the desired return force, then use the snap ring to secure the washer and spring into place.
The operating pressure range for ZS - Z slider is 0.15∼0.7 MPa [22∼102 psi].
