Linear Technical

DGZ Technical Description

Four parallel guide shafts (2) and a special guide profile (3) form the main body of the linear unit DGZ.
A rotating movement is transformed into the linear movement of the guide table (12) by means of a timing belt (14). The upper and lower parts of the guide table are joined together by a reinforcing plate (10),

Timing Belt

GT/HTD timing belt with steel insert:
pitch: 5mm
width: 25 mm

Pulley Boxes

Aluminum, black powder-coated

Guide Table

Extruded aluminum, clear anodized

Guide Profile

Extruded aluminum, clear anodized

Guide Shaft

Heat-treated steel, inductively hardened. Surface hard-chrome plated HRC 62

Bearing	Shaft bearing: single-row sealed grooved ball bearing. Guide table bearing: 8 sealed rollers (corresponds to a double row angular contact bearing).

Fixation of the Linear Unit	Fixation by means of tapped holes on the side of the pulley box or by means of slot stones in the guide profile.
