✦ Single-row crossed roller configuration – Cylindrical rollers positioned alternately at 90° within a single raceway, providing line contact with both axial and radial raceways.
✦ External gear on outer ring – Gear teeth are hobbed on the outer circumference with a 20° pressure angle spur profile and induction-hardened flanks.
✦ Forged ring construction – Both inner and outer rings are produced as single-piece forgings from 42CrMo4 steel, ensuring high structural integrity.
✦ Precision-ground raceways – Raceways are ground to a surface finish of 0.5 µm Ra and a tolerance class of P5 for smooth operation.
✦ Induction-hardened raceways – Rolling surfaces hardened to 58–62 HRC with a case depth of 2.0–3.0 mm, while gear teeth are hardened to 50–55 HRC.
✦ Integrated seal grooves – Seal channels are machined into both rings to accommodate standard NBR or FKM lip seals.
