Both the 013 and 014 series consist of an inner ring, an outer ring with internal teeth, and a single row of steel balls. The raceways are precision-machined to enable four-point contact between each ball and the raceways. This design allows the bearing to support axial loads (in both directions), radial loads, and tilting moments simultaneously – all within a single row.

The internal gear is integrally machined on the outer ring, allowing direct pinion drive coupling. This simplifies the transmission system, reduces component count, and improves overall drive efficiency.

Performance Highlights

• Higher load capacity: The 013 and 014 series feature larger cross-sections and larger ball diameters compared to the 011/012 series, resulting in significantly higher dynamic and static load ratings.

• Enhanced rigidity: Optimized raceway geometry and increased ring thickness provide superior structural stiffness under heavy tilting moments.

• Smooth operation: Precision-ground raceways and controlled ball-raceway contact ensure low friction and high rotational accuracy.

• Compact design: Despite the increased capacity, the single-row design maintains a relatively compact axial and radial envelope.
