External robolink® D rotary axis circular

robolink D joint for UR robots Certified for Universal Robots Plus.

Expand your UR robot's working area

The external robolink® D rotary axis allows circular workpiece movements. They are also often called slewing rings, rotary indexing tables or rotary tables, and allow continuous transport to various stations in a single work step. The radius of robot action is extended, making robots much more flexible in their applications. The rotary axis is driven electromechanically by a stepper motor via a gearbox with 48:1 transmission.
