Actuator KR46

THK

A compact, high stiffness, and highly accurate actuator with an integrated inner block consisting of an LM block and a ball screw nut.
Also, the housing A/B doubles as a support unit, and the inner block doubles as a table.
It has become possible to significantly reduce design and assembly labor-hours.

[Features]
・ Since it is arranged at a contact angle of 45° so that the load is equal in 4 directions, it can be used in any posture.
・ Since the straight guide section has a 4-row circular arc groove, there is no gap and highly stiff guidance can be obtained.
・ Changes in frictional resistance due to load fluctuations are minimized and follow high accurate feed.
・ The U-shaped cross-sectional outer rail improves stiffness against moments and twists.

Actuator KR45H

THK

With a compact and highly stiff structure that integrates the LM guide, ball screw, and support unit, 5 semi-custom made actuators ideal for high accurate positioning are available.
[Features]
[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: Positioning metal bolts are installed 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: THK and AFF grease are sealed for a clean environment to suppress dust generation
