Overview
NTN 23248K 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.
