Maintenance and Inspection
Periodic inspection is necessary for optimum use. Generally, annual inspection is recommended for the
rotary actuator. Even if no problem is found, seal parts replacement is recommended every three years. It
is highly possible that the actuator is operated out of specification when the components like pinion, piston,
bearing are broken. Please revise the operating condition. In this case, please return the broken actuator
to SMC to repair.
Regular check
Check the following for periodic inspection
(1) If the rotary actuator set screw has become loose
(2) If the rotary actuator set frame has become loose
(3) Is the operation smooth?
(4) Is there any leakage to outside?
If any items are found during the inspection that require repairing or tightening, either tighten the loose
components or disassemble the product to repair.
