Precautions
- *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.
- *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 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.
- *This product is dedicated to linear motion. The threaded portion can be rotated, but this product is not a rotary joint. It cannot be used for rotational applications.
- *Use the product at 25% or less of the allowable kinetic energy of the cylinder. *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, leading to breakage.
- *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.
- *See the manufacturer's catalog for product information other than the above.
