Frequently Asked Questions
What are the primary advantages of the WL20 series rotary actuators?
The WL20 series offers high torque, high bearing capacity, and a compact design, making it ideal for tight spaces and harsh environments.
Is an external brake required for these actuators?
No, these actuators feature zero internal leakage, which allows them to hold positions smoothly without the need for an external brake.
How does the actuator handle overload conditions?
It is equipped with a hydraulic fuse that allows for backdriving in overload conditions, effectively preventing mechanical damage.
What is the standard mounting type for the WL20 series?
The standard mounting type for all models in the WL20 series (from 005 to 042) is the Foot mount.
What output modes are available?
Available modes include Front Flange for smaller models, while larger models like the WL20-027 and WL20-042 support both Front and Double Flanges.
Can these actuators be used in marine environments?
Yes, the moving parts are fully enclosed, making them highly durable and suitable for harsh environments including marine and energy industries.
