The notes for Using
Be sure to read this before handling.

CAUTION
1. Applications

Floating connector is the floating joint that absorb misalignment and parallelism error in linear motion
between rod-type pneumatic, hydraulic, electric cylinders, etc. and workpiece. Although the threaded part isable to rotate, it is not rotating joint, so do not use this for rotation.

2. Design

If the support bracket type to mount a cylinder is trunnion type or clevis type, the swing angle is large andmay exceed the allowable eccentricity and rotating angle of the floating connector, causing damage orfailure. Do not use on trunnion type or clevis type cylinders.

3. Mounting

When connecting the cylinder rod and workpiece using the floating connector, tighten with the appropriate
torque depending on the thread size of the floating connector's socket, stud, case mounting hole, etc. Inaddition, if there is a concern that workpiece may fall off or be damaged due to loosening of screws, takemeasures to prevent loosening, such as using lock pins, locking washers, or applying adhesive.

4. Prevention of damage from impact force

Use the floating connector within the specified maximum working load (static load). When the workpiece isstopped, an impact load is generated due to inertia force, which may damage the floating connector. Installa buffer mechanism such as a shock absorber to prevent impact loads from occurring.

5. Disassembly

The floating connector is assembled using a high-strength adhesive and cannot be disassembled. etc. Also,
even if it can disassemble, do not use it reassemble again.

6. Usage environmentInstall a protective cover when the product will be exposed to liquids other than oil or in dusty locations.

7. Lublication

The floating connector is already filled with lubricating grease, so lubrication is not necessary. If it need alubrication, contact us please.

8. Maintenance

Before starting-up, check that there is no looseness in the connections between the floating connector,
cylinder rod, and driven body. Also, visually or impact sound check to see if there is a large gap in the axial
direction between the socket of the floating connector and the case when moving from compression torelease. If the gap becomes large, do not continue to use the floating connector and replace it.
