This deep groove ball bearing carries a spherical outer ring surface, allowing the outer ring to seat and align within a housing while the inner ring is designed for a fixed fit on the shaft. Bore diameter is 40.0 mm, outside diameter 80.0 mm, width 18.0 mm, and net mass is 0.32 kg. Sealing on both sides is of NPP type, protecting the internal raceway and balls from contamination. The spherical outer ring design compensates for angular misalignment between shaft and housing without requiring a separate spherical housing seat, which simplifies mounting and reduces sensitivity to shaft deflection or housing bore inaccuracies. The double-sided NPP sealing retains lubricant within the bearing and keeps out dust and moisture, making relubrication intervals longer and supporting stable running conditions once the bearing is fitted and aligned.
