drylin® tandem toothed belt axis

Toothed belt axis ZLWT with two parallel toothed belts for two linear carriages

Thanks to the double belt, the ZLWT tandem toothed belt axis is ideal if several linear carriages need to be moved quickly and independently of each other. The motors can be mounted on one side or on both sides. A parallel synchronous drive is also possible.

  • Addition to the tandem toothed belt axis installation size 10/20
  • Compact tandem toothed belt axis with two toothed belts in one unit
  • Two carriages can be controlled synchronously or separately
  • With drylin W exchange bearings for fast bearing exchange on the rail
  • Can be supplied ready-to-connect with igus  electric motors and drylin D1 dryve motor control system
Typical application areas: automation, robotics, assembly cells, painting systems
