Overview

Spherical roller bearing

Spherical roller bearings have two rows of barrel-shaped rollers running on a common spherical outer raceway, providing self-aligning capability. They accommodate very high radial loads and axial loads in both directions, absorbing misalignment from shaft deflection or mounting errors with virtually no increase in friction. They suit heavy-duty service in demanding environments such as paper mills, mining and wind power.

Key features

Self-aligning, absorbs misalignment
Very high radial and axial loads
Heavy-duty in harsh environments
Sealed variants for higher reliability

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.
