A compact, high stiffness, and high precision 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.
Therefore, 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 precision feed.
・ The U-shaped cross-sectional outer rail improves stiffness against moments and twists.
[Effect of adopting ball retainer]
·Due to the improved grease holding capacity, long-term maintenance-free operation has been achieved. (Lubricator QZ is attached to the ball screw section)
・ Excellent sliding performance can be obtained due to elimination of mutual friction between balls and reduced torque fluctuation.
・ In addition, the basic dynamic load rating of the LM guide and ball thread section is larger than before, so it has a long lifespan.
