  Actuator KR45H

  THK

  A compact, high stiffness, and high precision actuator with an integrated inner block consisting of an LM block and a ball screw nut.Also, since 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 precision feed.・ The U-shaped cross-sectional outer rail improves stiffness against moments and twists.

  Compact Series SKR20

  THK

  A compact, high-rigidity and high-precision actuator with an integrated inner block consisting of an LM block and ball screw nut.In addition, as the housing A/B serves as a support unit and the inner block serves as a table, it is possible to dramatically reduce the steps in designing and assembling.[Features] · Arranged to make contact at an angle of 45° such that the load is equal in 4 directions, enabling use in various positions. · The linear guide is made of 4 rows of circular arced grooves for a highly rigid guide with no cracks. · Changes to friction resistance due to changes in load are suppressed as far as possible, promoting high-accuracy feeding. · The U-shaped cross-sectional outer rail improves rigidity against moment and torsion.[Effects of Using Ball Retainer] · The grease retention capacity has been improved, allowing long-term maintenance-free operation. (QZ Lubricator is attached to the ball screw.) · Eliminates mutual friction between balls, reduces torque fluctuation and achieves excellent sliding performance. · In addition, since the basic dynamic load rating of the LM guide and ball screw is higher than conventional products, it has a long service life.
