Types and Options

Linear Cylinders

Compact, High Thrust Linear Actuator

Using aluminum for the rod, these motorized cylinders produce high thrust force despite their compact and lightweight body. The unique structure suppresses vibration to achieve improved acceleration characteristics and high-speed positioning operation.

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.

Quick & Responsive

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

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

Quick Response

Direction of Motor Installation

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

Space Saving

Cable Outlet Direction

Motor cable can be changed to any direction* by simply rotating
the stepper 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

Cable Direction

Application Example

αSTEP 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.

Reversed Motor Type

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

Space Saving

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.

Shaft Guide

Shaft Guide and Cover

There is no need to design or procure parts for the external guide. Moving parts on the cylinder main unit side are protected, improving equipment safety. This is useful for grease splash prevention in the shaft guide section and the prevention of the infiltration of foreign particles in the linear bush section.

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.
