Locating repeatabil ity 3 μm!!
Zero clearance between reference hole by expansion locating pin!!
Expansion Locating Pin
When releasing the clearance between pin and reference hole is big enough for smooth loading / unloading and conveyanceautomation.
Expansion locating pin expands and the clearance between pin and reference hole become zero which leads to locate withhigh accuracy.Also locking from the inside of the hole leads to zero backlash.
Locating repeatability: 3μm
Locate with high accuracy by expanding pin
General locating pin
Locating accuracy of general locating pin depends on clearancebetween pin and reference hole. Also it leads to inaccuracy of work and construction.

注意事項Expansion locating pin Cautions model VRA/VRC
Cautions
● Notes for design
1)Check the specifications
● This product compresses the pin by supplying air which allows
loading and unloading workpiece. When the air supply is shut
off and release the supplied air, it locates workpiece with
the internal spring. Use it with the combination of the expansion
pin for locating (-D) and one direction locating (-C).
The combination of (-D) and (-D), or (-C) and (-C) does not
satisfy the specification. When gripping only one workpiece hole
to convey lightweight work, use the expansion pin for locating (-D).
2) Please do not use under the environment where the product is
exposed to cutting chips and quenching liquid
3) The pitch tolerance for cyl inder and workpiece hole
pitch accuracy ● The pitch tolerance for cyl inder and the workpiece hole pitch
accuracy should be within ±0.02mm. I f the workpiece hole pitch
accuracy is not going to be within ±0.02mm, please make
the workpiece hole (-C) be s lot .

4)The reference surface towards the Pin’ s center axis.
● This product has no reference surface towards the center of its axis.
Please keep in mind the recommended clearance (0 .5~1)
and tool dimensions for mounting, and apply embedding
processing or prepare the seat separately for the proper center axis.
5)Mounting/removing workpiece (pallet)
● If needed, please apply a guide pin (rough guide) separately
to avoid increasing the force which exceeds allowable thrust
load when mounting/ removing workpiece (pallet).
5)Clamp mounting direction (phase)
● The mounting direction (phase) is important for high accurate locating.
Gripper part as a reference, please follow the figure below.
Adjustment procedure of mounting direction
① At mounting status, measure the
angle from the first direction of
gripper part to the desired direction.
② Loosen 1/4 of the hexagon part.
③ Use the location orientation hole
to rotate only the body of pin by
the angle measured in ①.
④ Tighten the hexagon part with
a prescribed torque wrench.
● Notes on installation
1)Check the fluid to use.
●Be sure to use clean air run through an air filter.
2)Disposal before piping.
● The pipeline, piping connector and fixture circuits should be
cleaned by thorough flushing.
The dust and cutting chips in the circuit may lead to fluid
leakage and malfunctioning.
● There is no filter provided with this product to prevent foreign
materials and contaminants from gett ing into the air c i rcuit .
3)Applying seal tape. (When using seal tape for piping)
● No seal tape need for thread part of expansion locating pin.
● Wrap with tape 1 to 2 times following the screwing direction.
● Pieces of sealing tape can lead to air leaks and malfunction.
● In order to prevent a foreign substance from going into the
product during piping work, it should be carefully cleaned
before work is started.
4)Mounting/ Removing cylinder
● When mounting cylinder, please apply grease to grease slot to
prevent burning.
Tighten the body with a torque wrench as shown in
the table below.
(Please do not tighten with an excessive torque wrench.)
1)It should be handled by qualified personnel.
● The hydraulic machine/air compressor should be handled and
maintained by qualified personnel.
2)Do not handle or remove the machine unless the safety is ensured.
① The machine and equipment can only be inspected or prepared
when it is confirmed that the preventative devices are in place.
② Before the machine is removed, make sure that the above-mentioned
safety measures are in place. Shut off the air of hydraulic source
and make sure no pressure exists in the hydraulic and air circuit.
③ After stopping the machine, do not remove until the temperature
cools down.
④ Make sure there is no abnormality in the bolts and respective parts
before restart ing the machine or equipment.
3) Do not touch workpieces (pallets) or cylinder while they are working.
Otherwise, your hands may be injured due to clinching.
4)Do not disassemble or modify it.
● If the equipment is taken apart or modified,
the warranty will be void even within the warranty period.
● Note on handling
① If the stipulated maintenance and inspection are not carried out.
② If the product is used while it is not suitable for use based on
the operator’ s judgement, resulting in defect.
③ If it is used or handled in inappropriate way by the operator.
(Including damage caused by the misconduct of the third party.)
④ If the defect is caused by reasons other than our responsibility.
⑤ If repair or modifications are carried out by anyone other than Kosmek,
or without our approval and confirmation, it will void warranty.
⑥ Other caused by natural disasters or calamities not attributable to
our company.
⑦ Parts expenses or replacement expenses due to parts consumption
and deterioration.
(Such as rubber, plastic, seal material and some electric components.)
Damages excluding from direct result of a product defect shall be
excluded from the warranty.
1)Warranty Period
● The product warranty period is 18months from shipment from
our factory or 12 months from initial use, whichever is earlier.
2)Warranty Scope
● If the product is damaged or malfunctions during the warranty
period due to faulty design, materials or workmanship, we will
replace or repair the defective part at our expense.
Defects or failures caused by the following are not covered.
● Warranty
3)Regularly make a tightening inspection to ensure proper use.
4) Regularly make an inspection that the supply air pressure level is
within the range of specification.
5)Make sure there is smooth action and no abnormal noise.
● Especially when it is restarted after left unused for a long preiod,
make sure it can be operated correctly.
6)The products should be stored in the cool and dark place
without direct sunshine and moisture.
7)Please contact us for overhaul and repair.
1)Removal of the machine and shut off of pressure source.
● Before the machine is removed, make sure that the above-mentioned safety
measures are in place. Shut off the air of hydraulic source and make sure
no pressure exists in the air circuit.
● Make sure there is no abnormality in the bolts and respective parts
before restarting.
2)Regularly clean the area around the machine.
● Continuous use with dirt on components will lead to locating
functions not work properly, leaking and malfunction.
When it does not work properly by cleaning only outside, it may
have contaminations of foreign substances to the machine inside and
damage to the internal part. In that case, please contact us for
overhaul (cleaning and replacing of internal parts).
Since it is a high-accuracy machine, when overhaul is conducted
by anyone other than Kosmek, the warranty will be void even
within the warranty period.

● Notes for design
1)Check the specifications
● This product compresses the pin by supplying air which allows
loading and unloading workpiece. When the air supply is shut
off and release the supplied air, it locates workpiece with
the internal spring. Use it with the combination of the expansion
pin for locating (-D) and one direction locating (-C).
The combination of (-D) and (-D), or (-C) and (-C) does not
satisfy the specification. When gripping only one workpiece hole
to convey lightweight work, use the expansion pin for locating (-D).
2) Please do not use under the environment where the product is
exposed to cutting chips and quenching liquid
3) The pitch tolerance for cyl inder and workpiece hole
pitch accuracy ● The pitch tolerance for cyl inder and the workpiece hole pitch
accuracy should be within ±0.02mm. I f the workpiece hole pitch
accuracy is not going to be within ±0.02mm, please make
the workpiece hole (-C) be s lot .

4)The reference surface towards the Pin’ s center axis.
● This product has no reference surface towards the center of its axis.
Please keep in mind the recommended clearance (0 .5~1)
and tool dimensions for mounting, and apply embedding
processing or prepare the seat separately for the proper center axis.
5)Mounting/removing workpiece (pallet)
● If needed, please apply a guide pin (rough guide) separately
to avoid increasing the force which exceeds allowable thrust
load when mounting/ removing workpiece (pallet).
