✦ Single-row crossed roller arrangement – Cylindrical rollers arranged alternately at 90° in a single raceway, providing line contact with both axial and radial raceways.
✦ External gear on outer ring – Gear teeth are integrally hobbed on the outer circumference, featuring a 20° pressure angle spur profile with induction-hardened flanks.
✦ One-piece forged rings – Both rings are manufactured as single-piece forgings from 42CrMo4 steel, ensuring uniform grain flow and structural integrity.
✦ Precision-ground raceways – Raceways are ground to P5 tolerance class with a surface finish of 0.4 µm Ra.
✦ Selective hardening – Raceways hardened to 58–62 HRC with a case depth of 2.0–3.0 mm, gear teeth hardened to 50–55 HRC.
✦ Integrated seal grooves – Seal channels are machined into both rings to accommodate standard NBR or FKM lip seals.
