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.

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.
