Important Safety Precautions

Do not allow the rotation speed of the chuck to exceed the maximum allowable 
speed limit. (Refer to pages 12-16)

For All Users

・If the rotation speed of the chuck exceeds 

the  rotation  speed  limit,  this  is  very 
dangerous  as  the  chuck  and  work  will  fly 
out.

The input force of the chuck (piston thrust, pulling force of the draw pipe) 
must not exceed the allowable maximum input force. 
(Refer to pages 12-16)

For All Users

・Input  must  match  the  specification  of 

the chuck.

・Adjust  the  hydraulic  pressure  to  the 

cylinder so that the input force, which 
determines  the  gripping  force  of  the 
chuck, does not exceed.

・Excessive  input  force  can  lead  to 

breakage  of  the  chuck,  which  is  very 
dangerous,  as  the  chuck  can  work 
can be damaged and fly out.

If you use the chuck with the inside diameter gripping, input force (hydraulic 
pressure) must be 1/2 or less of the allowable maximum input.
(Refer to page 16)

For All Users

・The  chuck  may  break  and  the  chuck 

or work could fly out.

Failure to follow the safety precautions below will result in 
serious injury or death.

DANGER

・If  it's  used  at  the  low  setting  pressure  and 

the  gripping  force  isn't  enough  against  the 

cutting  torque  or  centrifugal  force  can  lead 

to  breakage  of  the  chuck,  which  is  very 

dangerous, as the work can be fly out.

・If it's used at the excessive setting pressure 

can lead to breakage of the chuck, which is 

very  dangerous,  as  the  chuck  or  work  can 

be damaged and fly out.

・If  the  protrusion  is 

long,  the  tip  of  the 
work  can  turn  and 
the work fly out.

In case that a combination of cylinder is changed by model change,
it is necessary to change setting pressure.

Failure to follow the safety precautions below will result in 
serious injury or death.

DANGER

Keep the height of the jaw within the range specified in the gripping force limit table (Refer to page 15). 
If you must use a jaw taller than a standard soft jaw, use less than the input (piston 
thrust force, draw pipe drawing force) specified in the gripping force limit table.

For All Users

・Do  not  use  a  jaw  of  a  height  out  of 

the  range  of  the  gripping  force  limit 
table or a jaw with mass moment out 
of  the  range  of  the  gripping  force 
limit table. The chuck will break and 
the chuck and work will break and fly 
out.

For All Users

When the protrusion of the work is long, support it with 
the steady rest or center.

For All Users

Determine the gripping force required for processing by the machine tool manufacturer or user, 
and check that the required gripping force is provided before processing.
(Refer to pages 12-16 and cylinder manual)

・Adjust  the  hydraulic  pressure  to  the 

cylinder  to  obtain  the  required  gripping 
force.  If  the  gripping  force  is  insufficient, 
this is dangerous as the work will fly out.
