Piping; Precautions On Handling P6～P7 - SMC Networks CYV Series Operation Manual

3. Piping

1. The compressed air supply inlet of the cylinder has a unified thread. For this vacuum
rodless cylinder, use fitting for vacuum (with O-ring) commercially available.(Table 1)

2. Before piping, the used fitting and piping tube shall be cleaned and air-blown by clean air
carefully to remove oil and hazardous particles.
4. Precautions on handling
1. The max. operating pressure of the cylinder is 0.3MPa. If the pressure exceeds the max.
operating pressure 0.3MPa, a magnet coupling will come off and it may deteriorate the
proper operation and the feature to prevent particle generation.
2. In case of a vertical installation, the magnet coupling may come off, and the slide table
may drop. When the cylinder is mounted vertically, be sure to use it within the allowable
rate. If load (pressure) exceeds the allowable level, the magnet coupling may come off
and the slide table may drop. Pay great attention to the load and pressure control.
3. Do not use the cylinder when the magnet coupling is displaced. If an external stopper is
mounted outside of the cylinder at the time of displacement, remove the stopper and push
the slide table at the end of stroke (or push the piston moving component pneumatically)
to return it to the right position. （When pushing the slide table, do not use a bare hand.）
4. As this cylinder is non-lube type, no lubrication needs to be supplied to the operating fluid.
The internal surface of the cylinder tube is initially lubricated, so once the turbine oil or
other type of oil is supplied, the product specification might not be satisfied.
5. Do not supply the grease different from the one that has initially been applied to the
guide's sliding part. It may deteriorate the feature to prevent particle generation.
6. Be sure to use the cylinder in the clean environment. If corrosive gas is
present, the cylinder may corrode and its resistance might be deteriorated.
