The Basic idea of our NEW RL-D Joints is, that every Joint can be composed out of several components (Joint kit). Main differentiations are:
# Rotary sliding bearing igus PRT-01 (aluminum table with iglidur J sliding elements) or PRT-02-AL (aluminum ring with compact plastic ring made of iglidur J4) or PRT-02-LC (outer aluminum ring replaced by moulded outer ring => low cost solution).
# worm shaft made of hard anodized aluminum, or as injection moulded plastic part (iglidur RN33), additional materials as an Option.
# axial bearings of the worm shaft as roller bearings or thrust washer made of iglidur J.
# worm wheel currently made of iglidur J, additional materials will be offered in the future.
We have pre defined 3 general Solutions. Standard will make use of PRT-02-AL, hard anodized aluminum worm shaft with roller bearings. For the “high-end” solution, PRT-02-AL will be replaced by PRT-01, the low cost solution will contain PRT-02-LC, worm shaft made of iglidur RN33 and thrust washers as axial bearings => see Pictures. STEP data of all Solutions for 3 sizes attached.
Annotation: RL-D-50-xxx is currently only possible as high-end solution. PRT-02-AL or -LC are not yet available at igus.
