Abstract

A linear guide unit comprises a hollow elongated member of rectangular cross section, two parallel guide rails mounted on one wall of the elongated member, and at least one runner supported for movement on each of the guide rails. At least one wall of the elongated member other than the one on which the guide rails are mounted has a plurality of T-section grooves, which serve for the fastening of attachments. The runners are U-shaped, straddle the respective guide rails, and are carried on the said guide rails by closed rolling-member circuits. The elongated member may be combined with a variety of linear drive units of different types.
