✦ Single-row crossed roller arrangement – Cylindrical rollers are 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 integrally hobbed on the outer ring circumference, featuring a 20° pressure angle spur profile with induction-hardened flanks.
✦ Monobloc ring design – Both inner and outer rings are manufactured as single-piece forgings, providing seamless material integrity without welded or bolted joints.
✦ High-precision raceways – Raceways are ground and lapped to achieve a surface finish of 0.4 µm Ra and a tolerance class of P4 for high accuracy.
✦ Dual-zone hardening – Raceways hardened to 58–62 HRC with a case depth of 2.5–3.5 mm, while gear teeth are hardened to 50–55 HRC with a case depth of 1.5–2.5 mm.
✦ Integrated sealing system – Seal grooves are machined into both rings to accommodate heavy-duty labyrinth seals or standard NBR lip seals.
