This insert ball bearing carries a spherical outer ring and is fitted onto the shaft by means of an adapter sleeve rather than a straight bore, which allows the inner ring to be locked in position along the shaft after alignment. The outside diameter is 130.0 mm, the width is 44.5 mm, and the net mass is 2.62 kg. Sealing is provided on both sides by 2RSR seals, protecting the internal geometry from contamination. The adapter sleeve mounting method makes this bearing suited for shafts without a shoulder or stepped seat, giving flexibility in axial positioning during installation. The spherical outer ring seated in a matching housing allows the bearing to self-align, compensating for minor shaft misalignment or deflection. With sealing fitted on both faces, the bearing retains its internal lubricant and resists ingress of dust and moisture, reducing the need for frequent relubrication once mounted.
