The floating joint can absorb any off-centering orloss of parallel accuracy between the cylinder andthe driven body.
Centering is unnecessary.
A high level of machining accuracy is unnecessary.
The installation time is dramatically reduced.
It is compact and is suitable for high tensile stresses.

1.To screw the male threads of the rod into the female threads ofthe socket or the case, make sure that it does not bottom out.If the floating joint is used with its rod bottom out, the stud willnot be able to float, causing damage.For the screw-in depth of the female threads, refer to thedimensions (page 910). As a rule, after the rod bottoms out,back off 1 to 2 turns.The dust cover may be fixed with the stud, so loosen them
before using.2. When screwing stud or socket, or case in the driven
object, make sure to screw them in the state that dustcover has been removed from the case. If screwingwithout removing dust cover, duct cover might be broken.
3. To use a floating joint to connect the cylinder rod to adriven body, secure it in place by applying a torquethat is appropriate for the thread size. Also, if there isa risk of loosening during operation, take measuresto prevent loosening, such as using a locking pin orthread adhesive.In the event that the connected portion becomesloose, the driven body might lose control or fall off,leading to equipment damage or injury to personnel.
4. Do not use for rotational applications, because it isnot a fitting designed for rotational axis.
1. Do not reuse if disassembled.High strength adhesive is applied to the portion of theconnection that is threaded to prevent it fromloosening, and it must not be disassembled. If it isforcefully disassembled, it could lead to damage.

1. To screw the male threads of the rod into the
female threads of the socket or the case, make
sure that it does not bottom out. If the floating
joint is used with its rod bottomed out, the stud
will not be able to float, causing damage. For the
screw-in depth of the female threads, refer to the
dimensions (page 914). As a rule, after the rod
bottoms out, back off 1 to 2 turns.
The dust cover may be fixed with the stud, so
loosen them before using.
2. When screwing stud or socket, or case in the
driven object, make sure to screw them in the
state that dust cover has been removed from the
case. If screwing without removing dust cover,
duct cover might be broken.
3. To use a floating joint to connect the cylinder rod
to a driven body, secure it in place by applying a
torque that is appropriate for the thread size.
Also, if there is a risk of loosening during
operation, take measures to prevent loosening,
such as using a locking pin or thread adhesive.
In the event that the connected portion becomes
loose, the driven body might lose control or fall
off, leading to equipment damage or injury to
personnel.4. Do not use for rotational applications, because it
is not a fitting designed for rotational axis.
1. Do not reuse if disassembled.
High strength adhesive is applied to the portion
of the connection that is threaded to prevent it
from loosening, and it must not be
disassembled. If it is forcefully disassembled, it
could lead to damage.

How to Order
Operatingpressure
Pneumatic cylinder:1 MPa or less
Hydraulic cylinder:3.5 MPa or less
Basic styleMounting
Be sure to read before handling.Refer to front matters 54 and 55 forSafety Instructions.
1. For the screw-in depth of the female threads,refer to the dimensions (page 920).
2. When screwing stud or socket, or case in thedriven object, make sure to screw them in thestate that dust cover has been removed from the
case. If screwing without removing dust cover,duct cover might be broken.
3. To use a floating joint to connect the cylinder rodto a driven body, secure it in place by applying atorque that is appropriate for the thread size.Also, if there is a risk of loosening duringoperation, take measures to prevent loosening,such as using a locking pin or thread adhesive.In the event that the connected portion becomesloose, the driven body might lose control or falloff, leading to equipment damage or injury topersonnel.
4. Do not use for rotational applications, because itis not a fitting designed for rotational axis.
1. Do not reuse if disassembled.High strength adhesive is applied to the portion of
the connection that is threaded to prevent it fromloosening, and it must not be disassembled. If itis forcefully disassembled, it could lead todamage.
