Be sure to read this before handling

the products. Refer to back page 50

for Safety Instructions.

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 1152). 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.

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.
