The timing belt (7) converts a
rotating movement into a linear movement of the guide table
(4). A steel tape (2) covers the profile slot thus protecting
the guide unit
against dirt. |

Guides |
Adjustable
self aligning sliding bushings in polymer composite material with
high resistance to chock loads and vibrations |
|
|
Profiles |
Extruded
aluminum profile with integrated prisms for guiding and slots for
clamps and brackets for sensors and switches. Material: AlMgSi 0.5
anodized |
|
|
Covering Tape |
For
protection of drive mechanism and guidings, the profile is covered
with a coverband in stainless steel. Magnet bands ensure the
coverband is tight to the profile. |

Bearings |
All bearings
are deep groove bearings with pressed steel shields. |
|
|
Maintenance |
Shaft
bearing: single-row sealed grooved ball bearing.
Guide
table bearing: 4 sealed rollers (corresponds to a double row angular contact
bearing). |
