✦ Dual-row ball arrangement – Two independent rows of balls positioned in a back-to-back configuration, with each row having a distinct pitch circle diameter.
✦ Internal gear on inner ring – Gear teeth are integrally machined on the inner ring bore, with a spur tooth profile standardized for direct pinion engagement.
✦ Separate raceway channels – Each ball row operates in its own machined raceway channel, separated by a solid central rib that enhances structural integrity.
✦ Through-hardened rings – Both inner and outer rings are through-hardened to 45–50 HRC, with raceways induction-hardened to 55–60 HRC for wear resistance.
✦ Cross-section design – Features a tall, narrow cross-section with a height-to-width ratio of approximately 2:1, optimized for moment load resistance.
✦ Flat seal design – Equipped with low-profile NBR seals that sit flush with the ring faces to minimize overall bearing height.
