Function: The guide body consists of an aluminium square profile, with an integrated roller guide. The carriage is moved by a revolving interior nobbed belt. The advantage of this system: The belt is guided within the profile, so that the system is independent of the mounting position. The nobbed belt is self-tracking and has a very low operating noise level thanks to its nobs being offset by 45°. Furthermore, it is almost vibration-free in the transition sections. At the front face there is a timing belt deflection unit containing a toothed pulley with two coupling claws in the standard version. On the opposite side there is a bearing piece plate containing a tensioning device for the timing belt.
The carriage runs on 5 rollers which can be adjusted and serviced at each central servicing position.Two grease nipples at the carriage enable relubrication of the positioning system.
