✦ Roller arrangement – Cylindrical rollers are alternately oriented at 90° in a single raceway, with each roller maintaining line contact with both axial and radial raceways.
✦ External gear teeth – The outer ring features integrally cut gear teeth with a 20° pressure angle spur profile, featuring induction-hardened flanks.
✦ Ring construction – Both rings are manufactured as single-piece forgings from 42CrMo4 steel, ensuring seamless material integrity.
✦ Raceway finish – Raceways are ground to P5 tolerance class with a surface finish of 0.4 µm Ra.
✦ Heat treatment – Raceways hardened to 58–62 HRC with a case depth of 2.0–3.0 mm, gear teeth hardened to 50–55 HRC.
✦ Sealing system – Seal grooves are machined into both rings to accommodate standard NBR or FKM lip seals.
