Linear Slides

Compact & Powerful Linear Actuator

This linear actuator incorporates a ball screw and a THK-manufactured LM Guide™ as the guide. Since the high-accuracy LM Guide is directly installed in the enclosure base, these actuators are suitable for applications which require traveling parallelism. (Traveling parallelism 0.03 mm) Being compact and stiff, this series is effective in supporting large transportable mass.

Construction

Quick & Responsive

The high response of the closed loop motor and drive system provides superior short-distance positioning.

Since the AlphaStep AR Series operates synchronously with pulse commands and generates high torque with a compact body, it offers excellent acceleration performance and response

Quick Response

Capable of a Variety of Movements

Offering the ability from low speed to high speed or with light loads or heavy loads, these linear actuators are easier to use and offer high performance regardless of demanding operating conditions.

High-speed is possible with light loads or heavy loads, or even during inching operations.

High Speed Operation


Direction of Motor Installation

Reversed Motor types are provided for all linear actuators. This contributes to a shorter overall length and space savings.

Motor Installation

Cable Outlet Direction

Motor cable can be changed to any direction* by simply rotating
the motor. There is no need to leave space behind the motor since
the cable outlet is on one side of the motor, allowing for easy
connection and saving space.

*3 directions for Reversed Motor types

Application Example

Application Example

AlphaStep Control System

Hybrid Control System

The hybrid control system constantly monitors the motors position allowing for the benefits of performance from "open loop" control while providing the assurance of "closed loop " performance.

Space Saving

Motor Installation

Simple Maintenance for Reversed Motor Type

Maintainability has been improved by using Oriental Motor's unique belt tension adjustment mechanism and through the standardization of maintenance parts based on the AR Series.

Thanks to Oriental Motor's unique belt tension adjustment mechanism, belt replacement is easy.

If the screw is loosened, the belt tension is adjusted to an appropriate value by the force of the spring.

Simple Maintenance


X-Axis or Y-Axis Table

X-Axis or Y-Axis Table

Choose either X-Axis or Y-Axis Table type to meet the needs of your application.

X- or Y-Axis Table

Electromagnetic Brake

Vertical operation is possible with electromagnetic brake. The load position can be held when the power is cut off. Since the work will not fall in case of power failure or disconnection, you can safely use equipment in which the work moves vertically.
