✦ 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.

✦ Smooth low-speed control – The 14.5° pressure angle gear profile reduces friction spikes, ensuring steady rotation even at crawl speeds.

✦ Skew-free ball motion – Integral raceway shoulders keep each ball on track, preventing erratic movement that could cause vibration or noise.

✦ Tooth breakage resistance – The carburized gear core absorbs shock loads without fracturing, while the hard surface resists wear from repeated meshing.

✦ Vertical space savings – The narrow ring section allows the bearing to be installed in machines with limited axial clearance, such as compact indexing tables.

✦ Constant seal pressure – Pre-loaded seals maintain consistent lip contact over time, reducing the need for frequent adjustments or replacements.

✦ Reduced assembly complexity – The tandem ball layout simplifies the rolling element arrangement, making the bearing easier to assemble and inspect.
