Linear Technical

SQZ-II Technical Description

Two parallel guide shafts (6) and the guide profile (3) form the main body of the profile linear unit SQZ-II.
A rotating movement is converted into the linear movement of the guide table (12) by means of a timing belt (2).

Timing Belt

GT/HTD timing belt with steel insert:
pitch: 5mm
width: 8 mm (SQZ 30)
11 mm (SQZ 40, 40x80)
25 mm (SQZ 60, 60x120)

GT/HTD timing belt with steel insert:
pitch: 8mm
width: 28mm (SQZ 80x160)
40mm (SQZ 80)

Pulley Boxes

AlMgSi, black power coated. Connection surface non-painted

Guide Table

Extruded aluminum, clear anodized.

Guide Profile

Profile from the profile systems, clear anodized. Guide shafts are mounted onto the guide profile by means of a shaft housing profile.

Guide Shafts

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

Bearing	Shaft bearing: single-row sealed grooved ball bearing. Guide bearing table: 4 sealed rollers (corresponds to a double row angular contact bearing).

Fixation of the Linear Unit	Occurs through tapped holes on the lower side of the pulley box or through slot stones into the guide profile.
