ZIBOO NTN 1220 Self Aligning Ball Bearing 100x180x34mm

NTN 1220 Self Aligning Ball Bearing

The NTN 1220 is a self-aligning ball bearing designed for equipment that experiences shaft misalignment or deflection. It suits maintenance engineers and electricians who need a replacement component for motors, gearboxes or conveyor systems where precise alignment cannot be guaranteed.

Fits 100 mm shaft and 180 mm housing

With a 100 mm bore and 180 mm outside diameter, the bearing seats directly onto a standard shaft and into a matching housing bore. The 34 mm width occupies minimal axial space, freeing room for adjacent seals, spacers or retaining rings without requiring a redesign of the surrounding assembly.

Self-aligning design handles sustained misalignment

The spherical outer raceway allows the inner ring to pivot continuously under load, compensating for static and dynamic angular errors. This reduces edge loading on the balls during extended run periods, lowering heat build-up and extending service intervals compared with rigid deep-groove types.
