Precautions

Mounting

*When screwing the male threads of the rod into the female threads of the socket or the case, make sure that the rod 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 in the manufacturer's catalog. As a rule, after the rod bottoms out, back off 1 to 2 turns.
*The dust cover may stick to the stud. Move the dust cover at the base of the stud with your fingers, or twist the stud right and left gently to free it. When screwing the stud and socket or case into a driven body, make sure to remove the dust cover. Screwing without removing dust cover may break the dust cover.
*When using 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, etc., leading to equipment damage or injury to personnel.
*This product is not a rotary joint. It cannot be used for rotational applications.
*Be sure to use the cushion mechanism of the cylinder or a buffer mechanism such as a shock absorber to prevent impact force being applied to the floating joint when stopping the driven body. If there is no buffer mechanism, an impact force is generated that may cause the floating joint to exceed its maximum tensile and compressive force level.

Maintenance

*Do not use if the product has been disassembled. High-strength adhesive is applied to the portion of the connection that is threaded to prevent it from loosening. The product must therefore not be disassembled. If the product is forcefully disassembled, it could lead to damage.
*Black zinc chromate treatment is applied to the material surfaces of the case, flange and foot. In rare circumstances, white deposits may occur on the surface.

Other precautions

*See the manufacturer's catalog for information other than the above.
*Pictures are of representational models.
