imply installed.
7. Combined reserved spring seat and unique O-ring design are suitable for various occasions. They will make the actuator safer and more corrosion-resistant.
8. High-precision tooth profile on the gear and rack: The tooth engagement gap between the gear and the rack is smaller and more precise and the output power is larger.
9. selec high-quality support rings to reduce the friction coefficient of O-rings. So that the actuator will has long service life and a wide range of opera
