Mounting Precautions
- *1Maintenance space
Allow sufficient space for maintenance and inspection. - *2Operate the socket by hand before mounting to ensure it moves smoothly.
The dust cover may stick to the socket. Move the dust cover at the base of the socket with your fingers, or twist the socket right and left gently to free it before mounting. - *3Tighten the product to the appropriate torque for the screw size using an appropriate tool. In addition, apply a locking adhesive.
When connecting the driven object to the cylinder rod with a floating joint, hold the octagonal and square parts with an appropriate wrench and tighten the floating joint to the appropriate tightening torque according to the table below.
The floating joint may be broken or malfunction if parts other than the octagonal or square parts are gripped and rotated with pliers or a wrench, or if it is tightened to an excessive torque.
As a countermeasure against loosening caused by vibration or other reasons, apply locking adhesive. - *4See the manufacturer's catalog for product information other than the above.
Reference drawing for correct mounting of JT Series Floating Joint
- *Tighten with the rod end nut attached to the cylinder.
- *Screw the floating joint all the way to the end face.
