✦ Dual-row ball arrangement – Two rows of balls configured in a tandem layout with distinct pitch diameters, creating a wide load-bearing base for enhanced stability.
✦ Internal gear on inner ring – Gear teeth are precision-shaped on the inner ring bore, with a 14.5° pressure angle for reduced friction and smoother engagement.
✦ Integrated raceway shoulders – Each ball row is flanked by integral shoulders that guide ball movement and prevent skewing during operation.
✦ Soft gear core – Gear teeth undergo carburizing and quenching, resulting in a hard surface (58–62 HRC) with a tough, ductile core that resists tooth breakage.
✦ Narrow-section rings – Both rings feature a reduced axial height, with a height-to-width ratio of 1:3, making them ideal for applications with limited vertical space.
✦ Pre-loaded seal design – Seals are installed with a slight interference fit to maintain constant lip pressure against the ring surface, ensuring reliable sealing over time.
