Note 2) May be restricted depending on the cup diameter, mounting orientation, or workpiece. Please use within the max. work
load. Suction and transfer exceeding the max. work load may result in reduced vacuum pressure due to air leakage.
3.2. How to calculate theoretical lifting force
This manual shows how to calculate theoretical lifting force only. Refer to the catalog of suction cups for further
detail of suction cup selection method.
■How to calculate theoretical lifting force
The theoretical lifting force of a cup can be found by calculation or from the theoretical lifting force table.
Calculation
Theoretical lifting force table
The theoretical lifting force (not including the safety factor) can be determined by the cup diameter and vacuum
pressure.
The required lifting force can then be determined by dividing the theoretical lifting force by the safety factor t.
Lifting force = Theoretical lifting force / t
Theoretical lifting force (Theoretical lifting force = P x S x 0.1)

7.Maintenance
■ Implement the maintenance and check shown below in order to use the vacuum gripper
safely and in an appropriate way for a long period of time.
7.1. Maintenance for suction cups with flange
Caution
1）Check before and after the maintenance work
When the product is to be removed, turn off the power supply, and be sure to cut off the supply pressure and
exhaust the compressed air. Confirm that the air is released to atmosphere.
When mounting the product after the maintenance work, supply compressed air, connect to the power, check
if it functions properly and have a leakage inspection.
2）Maintenance should be performed according to the procedure indicated in the Operation Manual.
Improper handling can cause damage and malfunction of equipment and machinery.
3）Maintenance work
Compressed air can be dangerous when handled incorrectly. Therefore, in addition to observing the product
specifications, replacement of elements and other maintenance activities should be performed by personnel
with sufficient knowledge and experience pertaining to pneumatic equipment.
4）Draining
Remove condensate from air filters and mist separators regularly. If the collected drainage is drained to the
downstream side, it can stick inside of the product, causing operation failure and failure to reach the specified
vacuum pressure.
5）Do not disassemble or modify the product, other than the replacement parts specified in this manual.
7.2. Maintenance for suction cup
Caution
1）Suction cups are disposable. Replace them on a regular basis.
Continued use of suction cups will cause wear and tear on the gripping surface, and the exterior dimensions
will gradually get smaller and smaller. As the cups’ diameter gets smaller, their lifting force will decrease,
though gripping will still remain possible.
It is extremely difficult to provide advice on the frequency of suction cup replacement. This is because there
are numerous factors at work, including surface roughness, operating environment (temperature, humidity,
ozone, solvents, etc.), and operating conditions (vacuum pressure, workpiece weight, pressing force of the
suction cups on the workpieces, presence or absence of a buffer, etc.).
(The weakening of bent parts or the wear or sticking of rubber parts may occur with the bellows type cup.)
Thus, the customer should decide when suction cups should be replaced, based on their condition at the
time of initial use.
The bolts may become loose depending on the operating conditions and environment. Be sure to perform
regular maintenance.
＜How to replace the suction cup＞
・Pull the lock ring upward, and, after lifting it up to the adapter, remove the old cup by pulling it downward.
・While holding the lock ring in the raised position place a new cup onto the adapter.
・Confirm that the cup is securely in place, and then return the lock ring to its original position.
 The cup without lock ring is just inserted to the end of the adapter.

2) Mesh
If it is used in such a way that foreign matter is absorbed from the air or the workpiece, the mesh may become
clogged. If the mesh is clogged, it will cause a reduction in the ejector performance. Clean the mesh
periodically as necessary by washing, air blow and so on. If mesh clogging cannot be improved by cleaning,
replace plate B.
･Part number for plate B for replacement : ZXP7-APL1-A-X1
Refer to "6.1 Change to one cup" for the replacement method.
8.Precautions
8.1 Air supply
Warning
■Use clean air.
Supply air containing foreign matter, water, oil, condensate, etc., can cause malfunction of the supply valve and release
valve. So, install air preparation equipment on the upstream side of the product (refer to the piping example below) and
perform maintenance periodically to control the supply air properly.
Refer to "SMC Air Preparation System" for further details on compressed air quality.

8.2Suction cups with flange precautions
■Designing
Warning
If power or air supply is shutdown, vacuum pressure may decrease and this product may drop a
workpiece during gripping.
Please perform of safety measures by customer systems.
■Mounting
Warning
1) Tighten to the specified tightening torque.
If the tightening torque is exceeded, the body and the mounting screws may break. However, insufficient
torque may cause displacement of the body and loosening of the mounting screws.
2) Hold the product itself when handling.
It can cause the malfunction of the product.
■Piping
Caution
1) Flushing of the inside of the pipes
Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips,
cutting oil, and other debris from inside the pipe.
2) Tube attachment
・Take a tube having no flaws on its periphery and cut it off at a right angle. When cutting the tube, use tube
cutters TK-1,2,3,5, or 6. Do not use pliers, nippers, scissors, etc. If cutting is done with tools other than tube
cutters, the tube may be cut diagonally or become flattened, etc., making a secure installation impossible,
and causing problems such as the tube pulling out after installation or air leakage. Allow some extra length
in the tube.
・Grasp the tube and push it in slowly, inserting it securely all the way into the fitting.
・After inserting the tube, pull on it lightly to confirm that it will not come out. If it is not installed securely all the
way into the fitting, this can cause problems such as air leakage or the tube pulling out.
3) Tube detachment
・Push in the release button sufficiently, pushing its collar equally around the circumference.
・Pull out the tube while holding down the release button so that it does not come out. If the release button is
not pressed down sufficiently, there will be increased bite on the tube and it will become more difficult to pull
it out.
・When the removed tube is to be used again, cut off the portion which has been chewed before reusing it. If
the chewed portion of the tube is used as is, this can cause trouble such as air leakage or difficulty in removing
the tube.
4) Other Tube Brands
When using other than SMC brand tube, confirm that the following specifications are satisfied with respect to
the tube outside diameter tolerance.
・Nylon tube Within ±0.1mm
・Soft nylon tube Within ±0.1mm
・Polyurethane tube Within+0.15mm, Within -0.2mm
Do not use tube which do not meet these outside diameter tolerances. It may not be possible to connect them,
or they may cause other trouble, such as air leakage or the tube pulling out after connection.
5) Do not apply unnecessary forces, such as twisting, pulling moment loads, vibration, impact, etc., on
fittings or tubing.
6) Tubing, with the exception of coiled tubing, requires stationary installation. Do not use standard tubing
(non-coiled) din applications where tubing is required to travel inside the flexible protection tube.
Tubing that travels may sustain abrasion, extension, or severance due to tensile force. The removal of
tubing from the fitting may also occur. Use caution prior to use in an application.
・Do not lift the product body with the tube after connecting the tube to the product. Otherwise, damage to the
one-touch fittings may occur. For details, refer to the “Handling Precautions for SMC Products” on the SMC
website: https://www.smcworld.com

Vertical lifting
(This type of application should generally be avoided.)
7) Adjust the length of air tube following by the movement of the robot arm to avoid adding tension the
tube.
When adding the tension of tube repeatedly, it may result in air leakage.
And the tube bending radius in the vicinity of the fitting should be at least the minimum bending radius of the
tubing.
■Workpiece
If water drops or dust are attached on the workpiece surface, they may go into the vacuum ejector and may cause
the low vacuum performance. Also when workpieces are permeable, there is a case that sufficient lifting force
cannot get. In such cases, it is necessary to perform a suction test to check the compatibility to your application
before actual usage.
8.3Suction cup precautions
■Design
Warning
1）In cases where the workpieces are heavy or dangerous objects, etc., take measures to address a
possible loss of gripping force (installation of a drop prevention guide, etc.).
In the case of transportation by vacuum gripping using suction cups, the gripping force is lost when there is a
drop in vacuum pressure. Furthermore, since vacuum pressure can also deteriorate due to the wear and
cracking of cups, vacuum leakage from piping, etc., be certain to perform maintenance on vacuum
equipment.
■Selection
Caution
1）The cup materials which can be used differ depending upon the operating environment.
An appropriate cup material should be selected. Furthermore, since suction cups are manufactured for use
with industrial products, they should not come into direct contact with medicines, food products, etc.
2）Depending upon the weight and shape of the workpieces, the diameter, quantity, and shape of cups
suitable for use will vary.
Refer to “3.2. How to calculate theoretical lifting force” for the theoretical lifting force. Also, the selectable
cups will differ based upon conditions other than the above, such as the condition of the workpiece surface
(presence or absence of oil or water), the workpiece material, and its gas permeability. Confirmation is
necessary by actually performing vacuum gripping on the subject workpieces.
3）Do not apply an impact or large force to a cup when gripping a workpiece.
This will cause the deformation, cracking, and wear of the cup to be accelerated. The stiffening ribs, etc.,
should touch lightly, while staying within the cup skirt’s deformation range. Positioning should be performed
accurately, especially in the case of small-diameter cups.
4）When transporting vertically, factors such as acceleration, wind pressure, and impact force must be
considered in addition to the workpiece weight.
Use caution particularly when lifting items such as glass plates and circuit boards because a large force will
be applied by wind pressure. When a workpiece which is oriented vertically is transported horizontally, large
forces are applied by acceleration when movement is started and stopped. Furthermore, in cases where the
cup and workpiece can slip easily, accelerations and decelerations of horizontal movement should be kept to
a minimum.
5）When transporting flat shaped workpieces that have large surface areas using multiple cups, care
must be taken in arranging the cups, so that the workpieces are evenly gripped.
6）Use caution since the workpiece could rotate during transfer.
Use of more than one cup for each workpiece is recommended.
