Overview

NTN SA4-22B 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.
