✦ Single-row crossed roller arrangement – Cylindrical rollers are positioned alternately at 90° within a single raceway, each roller maintaining line contact with both axial and radial raceways.
✦ External gear on outer ring – Gear teeth are integrally machined on the outer circumference with a 20° pressure angle spur profile, featuring induction-hardened flanks to 50–55 HRC.
✦ Monobloc ring construction – Both inner and outer rings are manufactured as single-piece forgings, providing seamless material integrity without welded or bolted joints.
✦ Precision-ground raceways – Raceways are ground to P5 tolerance class with a surface finish of 0.4 µm Ra for minimal friction.
✦ Dual-zone hardening – Raceways 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, FKM, or silicone seals.
