✦ Three-row roller arrangement – Two axial rows (upper/lower) and one radial row, each with cylindrical rollers arranged in a triangular load path for balanced force distribution.
✦ Internal gear on inner ring – Gear teeth are precision-machined on the inner ring bore with a 20° pressure angle, case-hardened to 50–55 HRC.
✦ Two-piece outer ring – Outer ring is split horizontally into two bolted sections to allow access for roller installation and adjustment.
✦ Integrated axial/radial raceways – Axial raceways are ground directly into the inner ring faces, while the radial raceway is ground on the inner ring outer diameter.
✦ Induction-hardened profiles – All raceways hardened to 58–62 HRC with a case depth of 3.5–4.5 mm for extended wear life.
