          Overview

          NTN 21310CK Spherical Roller Bearing is a heavy-duty bearing that tolerates shaft misalignment and deflection through spherical raceways and barrel-shaped rollers. It supports high radial load and axial load in both directions, making it suitable for mining, steel, paper, wind, and other shock-prone equipment.

          The outer ring has a spherical raceway, while the inner ring carries two rows of rollers guided by a cage. This self-aligning structure compensates for minor shaft and housing misalignment during operation.

          Key features

          • ·Self-aligning capability for misalignment and shaft deflection
          • ·High radial and bidirectional axial load capacity
          • ·Stable operation under shock and vibration
          • ·Long-life design for heavy-duty equipment

          Typical applications

          • ·Conveyor pulleys
          • ·Crushers, screens, and mining equipment
          • ·Steel and paper machinery
          • ·Wind turbines and heavy machinery

          Selection guidance

          Review load, speed, misalignment, lubrication method, bore type, and adapter sleeve requirements before selection.
