○Determine the length of the draw pipe as shown below.
○When screwing the draw pipe into the piston, screw in a state that the piston fully comes outside.
9−3 Production and attachment of draw pipe
9−4 Attachment of cylinder
・When removing/installing the cylinder, use a lifting belt and perform as follows. (Fig.13)
1. To lift up the cylinder, engage a lifting belt with the draw-pipe and lift up the cylinder while supporting it.
2. Insert the draw-pipe into the spindle.
3. When a lifting belt comes close to the spindle, shift the lifting belt toward the cylinder.
4. When the draw-pipe has entered the spindle sufficiently, re-engage a lifting belt with the cylinder body and fit the
cylinder closely to the spindle and then install the cylinder with the cylinder mounting bolts.
・Use a lifting belt when attaching and detaching the cylinder to and from the machine, as there is a danger of
injury or damage if the cylinder drops.
・Use the belt in the center of gravity not to lose the balance, and lift the draw pipe slowly. If balance is bad, the
belt slips, and the cylinder drops, and there is the injury danger such as blows.
・Sufficiently degrease and apply adhesive on the thread part of the piston and the thread part of the draw pipe,
and then screw in and tighten.
・If the screw is loose, the jaw stroke of chuck will shorten, which could allow the work to fly out.
Table 10
The dimension L in Fig. 11 is determined from the distance A between the cylinder adapter and the back plate.
Example) In the case of B-206, S1246, the cylinder adapter and back plate distance A = 800,
The total length of the draw pipe is to be L = A + 41 = 800 + 41 = 841.
At the time of the screw process of the dimension a, the precision is to be JIS 6H and 6h, 6g matching the screw of the
piston of the cylinder. Pay attention so that the thread parts on both ends and the inner periphery do not swing or
become unbalanced.
・Provide sufficient strength for the draw pipe. If the draw pipe is broken due to insufficiency of the strength, the
gripping force will be lost instantly, which is dangerous as the work will fly out.
・Keep the dimension e and the dimension f in Fig. 11 for the draw pipe and a material with the tensile strength
380MPa (38kgf/mm
2
) or more must be used.
・The personnel who designed draw pipe must judge whether the strength of the draw pipe is sufficient for the
usage conditions.
・The dimensions and materials specified in this manual do not guarantee that the draw pipe will not break under
every usage condition.
・If the screw-in depth of the draw pipe to the draw nut is insufficient, the screw will break and the gripping force
will be lost instantly, which is dangerous as the work will fly out.
・If the draw pipe is unbalanced, vibration occurs, the screw is broken and the gripping force will be lost instantly,
which is dangerous as the work will fly out.
・If the engagement of the screw of the draw pipe is loose, vibration may occur resulting in breakage of the screw.
If the screw breaks, the gripping force will be lost instantly, which is dangerous as the work will fly out.

○Attach the drain port to be directly underneath. For its structure, if the drain port is not set directly underneath, the
hydraulic oil overflows from both ends of the sleeve body resulting in oil leakage.
・Doing so may cause oil leakage which could result in a fire. And if the hydraulic oil leaks, the gripping force of the
chuck will lower and the work may fly out, which is dangerous.
WARNING
Detach in the reverse
procedures of attachment.
