Manufacturer: Freebear Corporation Ltd.
Model: ARU-2444 Series

Features

• The unit with built-in rollers rises and lowers through air pressure.
  Compared with the freebear unit, the roller has a smaller starting frictional resistance (μ) in the rotational direction and is suitable for the direction turn and right-angle transfer in production line.

Specifications

※If the T-groove is deeper than 46mm, you need to adjust the height by installing a spacer underneath the ARU.
In such case, make sure that the ball extrudes 2mm from the upper surface of the bolster when the ARU rises.
