✦ Dual-row ball arrangement – Two rows of balls configured in a tandem layout with identical pitch diameters, creating a compact load-transfer path.
✦ Toothless ring surfaces – Both rings are machined with plain cylindrical faces, free of gear teeth, enabling external drive coupling.
✦ Single-block ring construction – Inner and outer rings are produced from single-piece forgings with no welded joints, ensuring uniform material properties.
✦ Induction-hardened raceways – Each raceway is hardened to 58–62 HRC with a case depth of 2.0–2.8 mm, providing a wear-resistant rolling surface.
✦ Low-profile cross-section – Rings feature a reduced axial height with a height-to-diameter ratio of 1:25, ideal for space-limited installations.
