Robolink D robot joint, symmetrical with two PRT slewing ring bearings

Slewing ring bearing (iglide® PRT) in a plastic housing. The main component is a worm gear The center borehole remains free for feeding cables etc through. The articulated joints can be ordered with or without motor.

Self-locking drive

light, compact and lubricant-free

Modular kit: Plastic housing + worm wheel made from iglide® J + worm shaft + PRT slewing ring bearings + axial roller bearings + radial bearings + VA screws

Adaptable to various motors, standard option: stepper motor NEMA17 / 23XL

INI kit for zero position optionally adaptable

3 options:

Standard: Aluminum-PRT (PRT-02-xx-AL), Aluminum worm shaft (AL hard anodized)
Application e.g. in our low-cost robot arms as front joints (RL-D-20 and RL-D-30)

Low-cost: Low-cost PRT (PRT-02-xx-LC), worm shaft made of plastic RN33
Application e.g. in manual adjustments

High performance: PRT design 01 (PRT-01-xx), Aluminum worm shaft (AL hard anodized)
