Floating Joint
The floating joint can absorb any “off-centering” or “loss of parallel accuracy” between the cylinder and the driven body.
Centering is unnecessary.
A high level of machining accuracy is unnecessary.
The installation time is dramatically reduced.
It is compact and is suitable for high tensile stresses.
Long service life (with dustproof cover)

PrecautionsBe sure to read before handling. Refer to pages 10-24-3 to 10-24-6 for Safety Instructions and Actuator Precautions.
1. 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 bottom out, the stud will not be able to float, causing damage.For the screw-in depth of the female threads, refer to the dimensions (page 10-19-4). As a rule, after the rod bottoms out, back off 1 to 2 turns.
2. When screwing stud or socket, or case in the driven object, make sure to screw them in the state that dust cover has been removed from the case. If screwing without removing dust cover, duct 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 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, leading to equipment damage or injury to personnel.
4. Do not use for rotational applications, because it is not a fitting designed for rotational axis.
Warning
Series JA
1. Do not reuse if disassembled.High strength adhesive is applied to the portion of the connection that is threaded to prevent it from loosening, and it must not be disassembled. If it is forcefully disassembled, it could lead to damage.

1. 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 dimensions (page 10-19-8). As a rule, after the rod bottoms out, back off 1 to 2 turns.
1. Do not reuse if disassembled.High strength adhesive is applied to the portion of the connection that is threaded to prevent it from loosening, and it must not be disassembled. If it is forcefully disassembled, it could lead to damage.

2. When screwing stud or socket, or case in the driven object, make sure to screw them in the state that dust cover has been removed from the case. If screwing without removing dust cover, duct 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 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, leading to equipment damage or injury to personnel.
4. Do not use for rotational applications, because it is not a fitting designed for rotational axis.

Note 1) Think of applicable bore size as a guide. For details, confirm the rod end thread diameter of a cylinder to be used in the catalog.
Note 2) For 3.5 MPa hydraulic cylinders, operate within the maximum tension and compression force.

Be sure to read before handling. Refer to pages 10-24-3 to 10-24-6 for Safety Instructions and Actuator Precautions.
Precautions
1. For the screw-in depth of the female threads, refer to the dimensions (page 10-19-14).
2. When screwing stud or socket, or case in the driven object, make sure to screw them in the state that dust cover has been removed from the case. If screwing without removing dust cover, duct 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 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, leading to equipment damage or injury to personnel.
4. Do not use for rotational applications, because it is not a fitting designed for rotational axis.
1. Do not reuse if disassembled.High strength adhesive is applied to the portion of the connection that is threaded to prevent it from loosening, and it must not be disassembled. If it is forcefully disassembled, it could lead to damage.
