The 11 series bearing consists of an inner ring, an outer ring with integral external teeth, and a single row of steel balls with spacers or cages. The raceways are precision-machined so that each ball maintains contact with the raceways at four distinct points, allowing the bearing to simultaneously support axial loads (in both directions), radial loads, and tilting moments within a single row of rolling elements.

The external gear is machined directly on the outer ring, enabling direct pinion drive coupling without the need for a separate gear ring. This simplifies the transmission system and reduces overall component count. Both rings are typically provided with mounting holes for straightforward bolted installation.

The series is commonly designated with a format such as 11-160300/1-0800, where the numbers indicate specific dimensional configurations. For example, models ranging from 11-160100/1-08100 through 11-160500/1-08140 represent a family of bearings with increasing outer diameters while maintaining the same section height.

Performance Highlights

• Combined load capability: Handles axial, radial, and moment loads simultaneously

• Compact and lightweight: Single-row design saves space and reduces structural weight

• Smooth rotation: Optimized raceway geometry provides stable operation under load

• Easy integration: External gear and mounting holes simplify system assembly

• Double seals: Typically equipped with double lip seals on both sides to prevent contamination and retain lubrication
