PRO280 Mechanical-Bearing Ball-Screw Linear Stage

Description

Design Features

  • Enhanced load capability versus the PRO115/165/225
  • Six models with travels from 300 mm to 1000 mm
  • Speeds up to 220 mm/s
  • Side-seal design with hard-cover protects from debris better than top-seal design
  • Cost effective; rugged design
  • Long-life linear motion guide bearing system

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.
