Aerotech: Linear Motor Drive Precision Stage (PRO280 Series)

Linear Stages

Aerotech manufactures a large selection of positioning stages including linear stage models that utilize our own brushless linear direct-drive servomotors, as well as ball-screw models driven with Aerotech brush or brushless rotary motors. Innovators in linear stage design, manufacture and integration, Aerotech builds linear positioning stages for high-performance applications in industrial robots, fiber optics and photonics, vision systems, machine tools, assembly, semiconductor equipment, medical component laser machining, laser micromachining, electronic manufacturing, and other industrial automation applications.

Aerotech linear stages are available in X, XY and XYZ combinations to meet your motion requirements.

PRO280 Mechanical-Bearing Ball-Screw Linear Stage

Design Features

When a PRO-style stage is desired, but more load capability is necessary, the PRO280 series is ideal. Similar in design to the PRO225 series, PRO280 series stages provide additional load carrying capability with larger bearings, a wider cross-section and a larger servomotor.

Rugged Construction

The hard-cover design provides protection from debris. The robust aluminum cover is hard-coated providing a scratch resistant surface.

The side seals keep dirt and particulates out of the stage and protect the bearing surfaces from contamination. The vertical orientation of the seals easily deflects debris away from the stage. The tabletop can be outfitted with an optional brush assembly to remove any particles that collect on the hard cover. Competitive top-seal designs can ingest debris in the seal, resulting in the eventual failure and replacement of the sealing mechanism.

NEMA 34 Motor Support

The PRO280 has a NEMA 34 motor flange mounting interface and can be ordered with an Aerotech standard brushless rotary motor installed. Alternatively, the stage can be ordered without a motor for the attachment of third-party DC brush, brushless or stepper motors.

Highly Configurable

The stage is equipped with a ground 5 mm/rev ball screw, and can be outfitted with English or metric bolt-hole pattern tabletops. A motor mounted brake option is available to prevent back driving the screw when power is removed from the servomotor with the stage in a vertical orientation. A fold-back kit is also available to effectively reduce the overall stage length for space-constrained applications.
