ECO225SL Series Mechanical Bearing, Ball-Screw Stage

Description

Design Features

  • High-performance in a cost-effective, economic package
  • Rugged mechanical design
  • Available with servomotor or stepping motor
  • Nine models with travels from 100 mm to 800 mm
  • Vacuum and cleanroom versions available

The ECO225SL is part of the ECO linear stage family, building upon Aerotech’s long tradition of producing low total cost of ownership motion designs. Excellent positioning specifications, high stiffness, and load capacity combined with economic pricing make the ECO225SL stage ideal for medium-performance production applications requiring higher load capability in a ball-screw stage.

Quality Mechanical Construction

A long-life recirculating linear guide bearing system and quality construction make the ECO225SL an attractive solution for applications where up-time is critical. Unlike low-cost competitive motion stages, the ECO225SL can be integrated into complex machines with the assurance it will perform at a high level and outlast other machine components.

Stepper Motor Option

For cost-sensitive applications, the ECO225SL series includes several NEMA 34 stepper motor options. With the ability to run on standard wall voltages, the ECO225SL provides plug-and-play capability with a minimal amount of supporting electrical equipment.

Design and Integration Flexibility

The ECO225SL is designed with many standard features and options that make the design adaptable to specific applications. It is available in nine different models with travels ranging from 100 mm to 800 mm and speeds up to 300 mm/s.

The base mounting holes are accessible from the outside of the stage for easy mounting. Standard mounting holes for both English and metric optical tables are present in all travels. Each stage also mounts to another ECO225SL for easy integration of multi-axis systems.

Optional tabletops are available with either English or metric mounting patterns. A third tabletop option features hole patterns to allow the direct attachment of several types of Aerotech rotary stages.

Aerotech BM or BMS series brushless servomotors are available with a variety of encoder options providing net resolutions ranging from 0.5 μm down to sub-nm. A holding brake can be added to the motor for vertical applications. A motor fold-back kit is available for space-constrained applications to reduce the overall stage length.

The ECO225SL stage series offers many options to fit the exact requirements of numerous applications. Its flexible, cost-effective design easily makes it one of the best value linear ball-screw stage series available today.
