Spherical roller bearing

A spherical roller bearing is a type of rolling-element bearing that supports a rotating shaft and can accommodate angular misalignment. These bearings use two rows of barrel-shaped rollers and a spherical outer raceway to handle large radial and axial loads. Their self-aligning ability makes them suitable for heavy-duty applications where shaft deflection or misalignment is expected.
Key features
Self-aligning: They automatically adapt to variations in the shaft's centerline, compensating for angular misalignment and shaft deflection.
High load capacity: Designed to handle very high radial and axial loads, exceeding the capacity of other bearing types like ball bearings.
Dual-row rollers: Typically contain two rows of rollers, which are supported by a common race, providing high load-carrying capacity.
Robust construction: Constructed from high-strength materials like nickel chromium alloy steels to withstand harsh conditions.
Versatility: Available in various sizes and types, including thrust bearings that handle very high axial loads even with shaft misalignment.
