Single Axis Actuators（Accuracy：Standard Grade）

■ What is an actuator?
An actuator consists of a ball screw, guide, bracket and bearing holder, and it converts rotational motion into linear motion. It is mainly used for transportation and positioning.
MISUMI handles single-axis robots, single-axis actuators and single-axis units, which can be selected with one click in various sizes, types and specifications according to the applications and functions.
■ Features
· MISUMI Products: High accuracy, high rigidity, compact LX, low-cost LS, KU that's ideal for high accuracy and high load capacity. You can select LX with motor (servo motor, stepper motor) or without motor. Fast delivery and low price even on a large order.

Actuator SKR33

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
[Selection of sensors and sensor rails]

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.

Actuator SKR26

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.

[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.
