Caution
As a jig is required for bore size ø6, do not disassemble when replacing seals etc.
If overhaul is required, contact SMC Sales Office.
Checks
1.Daily check
1)Whether the operation is smooth or not.
2)Changes in piston speed and cycle time.
3)Whether the stroke is appropriate or not.
2.Regular inspection
1)Loosening of the cylinder mounting screw
2)Whether the operation is smooth or not.
3)Changes in piston speed and cycle time.
4)External leakage
5)Whether the stroke is appropriate or not.
6)If there are any scratches on the piston rod, and the grease condition.
7)Whether drainage in the air filter is regularly discharged or not.
Check the points above at least, and contact the sales representative if any failure is found.
4. Basic Circuit for Cylinder Operation
The basic circuit for operating the product with air filter, regulator, solenoid valve and speed controller is shown in the
following figure.
Regulator
Speed controller
Solenoid valve
Air cylinder
Air filter Pressure sorce
For a double-acting cylinder, use a meter-out speed controller
For a single-acting cylinder, use a meter-in speed controller.
Open the speed controller gradually from the fully closed position to adjust the speed.
Do not adjust the speed starting with the speed controller in the fully open position,
otherwise, damage may occur due to the piston striking the end cover at high speed.
