Spherical roller bearings are self-aligning bearings that, due to their structure, are often used to carry heavy loads when deformation and misalignment occur simultaneously, e.g. in heavy machinery. Spherical roller bearings are bearings with an innovative design - extremely effective solutions whose unique design is based on spherically ended barrels. Thanks to this, they allow exceptional deflections from the axis, which makes them ideal in places with significant shaft deflection.

Variety of Applications.

They are characterized by universality, perfect for large-sized machines, where they carry large axial and radial loads. Swinging variants work great on loose housings, eliminating the need for shaft and housing coaxiality. However, longitudinal models operate efficiently at high rotational speeds, even with misalignment of up to 3 degrees.

Design and features

Self-aligning spherical roller bearings carry both longitudinal and transverse loads thanks to the skew arrangement of the rolling elements. Longitudinal models, despite their ability to carry large longitudinal loads, are also effective at high rotational speeds.

Durability and lubrication:

Thanks to their ability to carry heavy loads, spherical roller bearings are extremely durable. However, they require special cages to prevent the rolling element from being mown. Normally, lubrication with grease is recommended, although oil lubrication is also suitable. These bearings are separable, which facilitates installation and maintenance.

Types of spherical roller bearings:

Spherical roller bearings come in single-row, double-row and three-row versions. Single-row ones have one row of barrels and allow angular shaft deflections. Double rows are ideal for heavy loads, ensuring load balance on the rolling elements. Three-row, thanks to the integration of seals and the lack of the need for pre-tensioning, are perfect for carrying heavy loads.

Universal use:

Spherical roller bearings are used in heavy machinery, including gears, foundry machines, industrial fans, and wherever large radial loads occur. Thanks to their unique structure, they allow operation in conditions that exclude the use of other types of bearings.
