Mounting Maintenance

Warning Warning1. 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 di-mensions (page 1139). As a rule, after the rod bottoms out, back off 1 to 2 turns.

2.The dust cover may stick to the stud. Move the dust cover at the base of the stud with fingers, or twist the stud right and left gently to free them.And when screwing stud or socket, or case in the driven ob-ject, make sure to screw them in the state that dust cover has been removed from the case. If screwing without removing dust cover, dust cover might be broken.

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 mea-sures 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 dedicated to the linear motion. The threaded portion can be rotated, but this product is not a fitting designed for rotational axis. So, do not use for rotational applications.

5. Use the product at 25% or less of the allowable ki-netic energy of the cylinder. When a driven object is stopped, be sure to prevent the impact force of the object being transferred to the product by adding the cushion mechanism of a cylinder or other cush-ioning devices such as a shock absorber. Other-wise, the impact force may exceed the maximum tensile and compressive force of the product, caus-ing breakage.

1. Do not reuse if disassembled.High strength adhesive is applied to the portion of the connec-tion that is threaded to prevent it from loosening, and it must not be disassembled. If it is forcefully disassembled, it could lead to damage.
