✦ Three-row roller configuration – Two axial roller rows (upper and lower) and one radial roller row, each with cylindrical rollers for line-contact load distribution.
✦ External gear on outer ring – Gear teeth are integrally machined on the outer ring circumference, featuring a spur tooth profile with induction-hardened flanks to 50–55 HRC.
✦ Monolithic inner ring – The inner ring is manufactured as a single forging, containing both axial raceways and the radial raceway in a unified structure.
✦ Raceway hardening – All raceways are induction-hardened to 58–62 HRC with a case depth of 4–5 mm for extended wear resistance.
✦ Heavy-section outer ring – The outer ring features an increased radial thickness and a width-to-height ratio of 1:1.4, optimized for tilting moment resistance.
✦ Roller guidance – Rollers in each row are guided by machined brass cages with precision-milled pockets for reduced friction.
