Overview

NTN 2320S Self-Aligning Ball Bearing uses two rows of balls and a spherical outer ring raceway to compensate for shaft misalignment. It provides low-friction rotation in fans, conveyors, textile machines, and long-shaft arrangements with mounting or housing deviations.

Two rows of balls are guided by a cage on the inner ring, while the outer ring has a spherical raceway. The design absorbs angular misalignment between shaft and housing while maintaining low friction at moderate to high speeds.

Key features

Self-aligning function for angular misalignment
Low friction for stable medium- to high-speed operation
Suitable for long shafts and deflection-prone positions
Available in open and sealed variants

Typical applications

Fans and blowers
Conveyor shafts
Textile machinery
Agricultural and general machinery

Selection guidance

Check expected misalignment, load, sealing needs, internal clearance, and available mounting space.
