| KNR hydraulic actuators |
AT KNR SYSTEM, we sell two types of hydraulic actuators: the KRH (Hydraulic rotary actuators) series and the KLH (Hydraulic linear actuators) series The KRH series consists of rotary actuators, which are used in rotary joints because they have high torque without any additional parts. The KLH series consists of linear actuators, which connect with other parts to perform rotary or radial movements. The RH/LH series can provide precise feedback control in closed-loops using servo valves and special sensors. In general, LVDTs are used as sensors in linear movements, and RVDTs or encoders are used as sensors in rotary movements. We also provide customized KRH/KLH actuator products for customers with specific needs.
KNR SYSTEM develops actuators according to the requirements of robots and unmanned systems. Our products have higher Force-to-Weight Ratios (FWR) than those of our competitors, and are able to withstand high force applied to the axis and rotary directions, making them strong application systems of their own.
■ Heavy load-carrying capacity
KNR’s unique design gives its products a high Force-to-Weight Ratio (FWR), making it useful in many ways. This design gives the products the ability to withstand high force to the axis and rotary directions, creating a strong system with high force density without the need for any additional parts.
■ Compact design
When a product is made from a small number of parts assembled firmly together, the compact formation allows single or double vane/stroke pumps to produce high torque/force power and reduces power loss caused by machine parts.
■ Flexibility
The axes used have holes with rod threads and have mounting dimensions of large diameters, allowing them to be applied in many ways through direct connection.
■ Low oil leakage
The sealant is applied on a precision-made smooth surface, preventing oil leakage effectively and allowing the maintenance of a fixed position without drift.
At KNR SYSTEM, we constantly interact with our customers to find what they need. We constantly try to meet their requirements, and always develop new products and technology of improved performance. In the future, we plan to develop and release a smart actuator, a product which combines a controller, hydraulic servo valves, and sensors. In accordance with this plan, we are currently preparing a sensor-integrated actuator and STEP 1 of the smart actuator development.
