Robolink D robot joint asymmetrical with a PRT slewing ring bearing and cover plate

Robolink D robot joint 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 self-lubricating

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

Application e.g. horizontal on base plate

3 options:

Standard: Aluminium-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:1 Low-cost-PRT (PRT-02-xx-LC), worm shaft made from plastic RN33
Application e.g. in manual adjustments

High performance:PRT design 01 (PRT-01-xx), aluminum worm shaft (AL hard anodized)
Application, e.g. as first rotary axis in Robolink - articulated arms
