robolink® D robot joint with two PRT slewing ring bearings
Slewing ring bearing (iglidur® PRT) in a plastic housing.
The main component is a worm gear. As a result
the central through hole remains free for the insertion
of, for example, cables. The articulated joints can be
ordered with or without a motor.
Self-locking drive
Light, compact and lubricant free
Construction kit: plastic housing + worm wheel made of iglidur® J + worm shaft + PRT slewing ring bearing + axial roller bearings + radial bearings + VA-screws
Adaptable to various motors, standard option: NEMA17 / 23XL stepper motors
INI kit for zero position optionally adaptable
