✦ Single-row crossed roller arrangement – Cylindrical rollers positioned alternately at 90° in a single raceway, enabling simultaneous contact with both axial and radial raceways.
✦ External gear on outer ring – Gear teeth are hobbed and induction-hardened on the outer ring circumference, featuring a standard 20° pressure angle spur profile.
✦ Monobloc ring construction – Inner and outer rings are manufactured as single-piece forgings, ensuring uninterrupted grain flow and 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 roller motion.
✦ Induction-hardened raceways – Rolling surfaces hardened to 58–62 HRC with a case depth of 2.0–3.0 mm, with gear teeth hardened to 50–55 HRC.
✦ Seal grooves – Integrated seal channels are machined into both rings to accommodate standard NBR or FKM lip seals.
