(12) Select a speed within the product's allowable energy value.
If the kinetic energy of the load exceeds the allowable value, it could damage the product, and
cause a hazard to humans, or damage the machinery and equipment.
(13) Provide a shock absorber if the kinetic energy that is applied to the product exceeds the
allowable value.
If the product's kinetic energy exceeds the allowable value, it could damage the product, and cause
a hazard to humans, or damage the machinery or equipment.
(14) Do not stop or hold the product at midpoint by keeping air pressure in the product.
For a product without an external stopping mechanism, if the directional control valve is closed to
keep the air pressure in the product, in an attempt to stop the product at midpoint, it might not be
possible to maintain that stopped position due to an air leakage. As a result, it could pose a hazard
to humans and cause damage to machinery and/or equipment.
(15) Give consideration to the decline in strength
caused by changes in the shaft shape.
Some shaft types, such as simple specials, may have shapes and dimensions that result in
decreased strength when compared with standard models. Consider this carefully when using
(16) Do not use two or more rotary actuators with the aim of synchronized movement.
One of the actuators may bear the load of operation, making synchronized movement impossible,
and possibly leading to deformation of the equipment.
(17) Do not use in a location where external leakage of lubricant could have an adverse effect.
The lubricant coating the interior of the product may leak to the outside of the product from
connecting parts of the rotary body, cover, etc.
(18) Do not disassemble the product or make any modifications, including additional machining.
This may cause human injury and/or an accident.
(19) Refer to the Auto Switches Precautions when using with an auto switch.
Caution
(1) Do not use below the adjustment range specified for the product.
If the product is used below the specified speed adjustment range, it could cause the product to
stick, slip, or the movement to stop.
(2) Do not apply external torque to the product that exceeds the rated output.
If an external force that exceeds the product's rated output is applied to the product, it could damage
the product.
(3) If it is necessary to provide repeatability of the rotation angle, directly stop the load externally.
Even with a product that is equipped with an angle adjuster, there are times when the initial rotation
angle could change.
(4) Do not use the product under hydraulic pressure.
The product will be damaged if it is used by applying hydraulic pressure.
(5) Do not use in a location where there are many temperature fluctuations.
When using in lower temperature applications, take care not to allow frost inside the cylinder.
Operation may be unstable.
(6) Perform speed adjustment in the environment in which the product is to be used.
Speed adjustments may be necessary if the environmental conditions vary.
(7) Adjust the speed control in the environment in which the product is to be used.
Speed adjustments may deviate if the environment changes.
