        Overview

        NTN 21310C 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.
