Mounting

Be sure to read this before handling

the products. Refer to back page 50

for Safety Instructions.

1. For the screw-in depth of the female threads,

refer to the dimensions (page 1158).

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 buf-

fer mechanism, an excessive impact force is gener-

ated. 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.
