Actuator KR26

THK

An actuator with a compact and high-stiffness structure that integrates an LM guide, ball screw, and support unit, making it ideal for high-precision positioning.
[Features]
・ In addition to the standard specifications, the manufacturer will semi-order 5 highly requested customs, and will promptly procure and ship after ordering.
[5 custom made]
・ Dowel holes: Dowel holes are provided for alignment during assembly. It is also useful for preventing misalignment and reproducibility when replacing products.
・ Positioning Metal Bolt: Install the positioning metal bolts for origin alignment during assembly. It is also useful for reproducibility of the origin position when replacing the motor.
・ Sub-table side greasing hole: By processing a grease hole on the side of the sub table and attaching a grease fitting, greasing is possible without removing the cover.
・ AP-C processing: Surface treatment (THK, AP-C treatment) is applied to improve corrosion resistance.
・ AFF grease for clean environment: Encloses clean environment-friendly grease (THK, AFF grease) to suppress dust generation.
[Selection of sensors and sensor rails]
・ Please refer to the selection list on the "Product Information" tab.
