✦ Single-row crossed roller arrangement – Cylindrical rollers positioned alternately at 90° within a single raceway, enabling line contact with both axial and radial raceways.
✦ External gear on outer ring – Gear teeth are integrally hobbed on the outer circumference with a 20° pressure angle spur profile and induction-hardened flanks.
✦ Monobloc ring construction – Both rings are produced 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.
