More flexibility for robots ...

New robot adapter kits for ZLW toothed belt axes

With the so-called 7th axis as linear adjustment, the radius of action of robots is extended and thus they become much more flexible in their applications. The drylin® ZLW-20 toothed belt axis is ideally suited as a wide low-profile linear axis. For this axis, two adapter kits are now available for the direct connection of robots robolink DP, robolink DCi  as well as Universal Robots with UR CAP integration. Optionally, the ZLW-20 toothed belt axis can be delivered ready for connection with the matching adapter kit or the adapter kit separately.

  • Flexible use of robots instead of locking kinematics
  • Connection via linear carriage of the ZLW-20 modular axis
  • Stroke lengths up to 3,000mm
  • Adapter kit including suitable e-chain systems®
  • Integration in the igus robot control
  • Integration into the UR CAP (control system UR via True Physics)
