Troubleshooting
Failure Possible causes Countermeasures
Actuator does not
operate.
Adjust speed
controller and check
that rotation speed of
Actuator is within the
specified speed
adjusting range.
Stable speed adjusting range is not satisfied.
Use the product within the specified speed
adjusting range.
Increase in internal leakage due to internal
packing damage caused by foreign matter and/or
oil.
Replace the vane shaft and stopper packing
(In general, the product requires replacement).
Sealing failure of internal packing or increase in
internal resistance due to the use out of the
specified operating temperature range (Including
freezing). Use the product within the specified operating
temperature range (In some cases of sealing
failure, the vane shaft and stopper packing
require replacement).
Failure of peripheral components:
a. Improper adjusting of speed controllers.
b. Malfunction of solenoid valves.
c. Air supply shortage due to clogging of air filter.
d. Decrease in pressure due to failure of
regulator.
Use special products (including measures
against problems of pneumatic circuit).
Shaft breakage
Large load energy:
a. Large load mass.
b. Fast operating speed.
c. Long rotation radius.
Replace the shaft.
a. Use the product with the allowable energy
range.
b. Install cushioning device and external
stopper to absorb impact energy.
External force other than load energy is applied.
Replace the shaft.
Avoid excessive external force.
Offset load due to de-centering. Replace the shaft.
Rotation angle failure
Breakage of the connection part of the rotation
axis or internal stopper.
Replace the connection part or product.
Bearing breakage
Overload (Loads in radial and thrust directions are
too heavy). Replace bearing: Make radial and thrust loads
be within the allowable range.
Offset load due to decentering. Replace bearing: Correct de-centering.
Large vibration. Replace bearing: Absorb vibration.
External leakage
Sealing failure of O-ring due to bearing damage
and/or shaft bending. Replace the bearing and/or shaft.
Relieve external force.
O-ring damage due to foreign matter and/or oil. Replace the O-ring.
Internal leakage
(Excluding increase
in internal leakage
due to life)
Packing damage due to foreign matter and/or
oil.
Replace the vane shaft and stopper
packing (In general, the product requires
replacement).
Prevent foreign matter and oil entrance.
Sealing failure of packing due to the use out
of the specified operating temperature range.
Replace the vane shaft and stopper
packing (The product requires replacement
especially for the use at high temperature).
Use the product within the specified
operating temperature range.
Notice on Trouble and Troubleshooting
1. Life is excluded from the causes.
2. Consult SMC for any causes other than those in the table above (except life) since the product may
require disassembling check.
