Nubbed belt drive
Function: The guide body consists of an aluminium square profi le with lateral, parallel, form-fit, internal hardened steel rods. The guide carriage, which is driven along the shafts by a nobbed belt, moves on the guide body with internal linear ball bearings that are adjustable free of play.
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.
