The 3300 Series double-row angular contact ball bearings feature a wider cross-section for increased combined load capacity compared to 3200 Series equivalents. The integrated double-row raceway eliminates the need for matched-pair mounting while providing robust axial guidance. Ideal for heavy electric motors, industrial ventilation fans, and material handling conveyor systems.
