✦ Single-row crossed roller configuration – Cylindrical rollers arranged alternately at 90° in a single raceway, ensuring line contact with both axial and radial raceways.
✦ External gear on outer ring – Gear teeth are precision-hobbed on the outer ring circumference, featuring a 20° pressure angle spur profile with induction-hardened flanks.
✦ One-piece forged rings – Both inner and outer rings are produced from single-piece forgings, eliminating welded or bolted joints.
✦ High-precision raceways – Raceways are ground to P5 tolerance class with a surface finish of 0.5 µm Ra for low 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 channels – Seal grooves are machined into both rings to accommodate standard NBR, FKM, or silicone seals.
