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 bottom 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 1146). As a rule, after the rod bottoms out,
back off 1 to 2 turns.
2. The dust cover may adhere to the stud. In this case,
move the dust cover at the neck of the stud by the
finger or twist the stud slightly left or right to break in
the dust cover before use.
Additionally, when screwing the stud and socket or
the case into a driven body, screw in such parts with
the dust cover removed. When screwing in such
parts without removing the dust cover, this may
cause damage to the dust cover.
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.
This product is not a rotary joint. So, the product cannot
be used for rotational or rotation acting applications.
5. Be sure to use the cushion mechanism of the cylinder
or the buffer mechanism, such as the shock absorber
so that any impact force is not applied to the floating
joint when stopping a driven body. If there is no buffer
mechanism, an excessive impact force is generated.
As a result, the tensile compression force of the
floating joint may exceed its maximum level.

Warning
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.

1. The black zinc chromate treatment is applied to
the material surfaces of the case, flange and foot.
However, the white deposit may rarely occur on
the surface. This white deposit does not affect the
product functions. However, if the white deposit
becomes a problem from a viewpoint of appear-
ance, special products with the surface treatment
changed to the electroless nickel plating are also
available. For details, please contact SMC.
