Spherical roller bearings
Spherical roller bearings are solutions engineered to operate under the most severe operating conditions, where conventional rolling bearings are unable to provide adequate rating life and system stability.
In this category, you will find spherical roller bearings designed for large-scale machinery, heavy loads, and variable operating conditions.

The Marat store offers products tailored to real-world industrial applications, where resistance, reliability, and the capability to compensate for mounting errors are critical. |
Spherical roller bearing – design and principle of operation
A spherical roller bearing is a rolling-element bearing in which the rolling elements are barrel-shaped rollers—rotating bodies with a slightly spherical profile. The spherical raceway of the outer ring allows the inner ring, along with the cage and rolling elements, to deflect. Consequently, a spherical roller bearing is inherently self-aligning and highly resistant to shaft misalignment and shaft deflections.
Most frequently, spherical roller bearings are available in a double-row configuration, allowing them to accommodate exceptionally heavy radial loads alongside axial loads—and in the case of double-row variants, even in both directions. The maximum permissible misalignment typically does not exceed 2°, yet even this value significantly enhances the operational safety of the entire system.
Spherical roller bearings – standards and reliability
Each spherical roller bearing available in our product range complies with specific requirements regarding load-carrying capacity, tolerances, and rating life.

Accordingly, you will find spherical roller bearings here that enable safe operation in systems exposed to heavy loads, vibrations, and harsh environmental conditions. |
Lubrication can be carried out using either grease or oil, which facilitates seamless integration into existing maintenance systems.
Spherical roller bearings – practical applications
Spherical roller bearings find application primarily in:
- heavy and large-scale machinery,
- the mining and metallurgical industries,
- heavy transport and heavy mechanical engineering,
- arrangements subjected to simultaneous heavy radial and axial loads.
This is the ideal solution wherever shaft misalignment, structural deflections, or operating conditions occur that preclude the use of conventional ball bearings.

FAQ
What distinguishes a spherical roller bearing?
A spherical roller bearing is a self-aligning bearing that, thanks to its barrel-shaped rolling elements, compensates for shaft misalignment while accommodating exceptionally heavy radial and axial loads.
For what applications are spherical roller bearings used?
Spherical roller bearings are utilized in heavy machinery, the mining industry, metallurgy, and transport—wherever heavy loads occur and shaft deflections are likely.
Do spherical roller bearings accommodate axial loads?
Yes, double-row configurations of spherical roller bearings in particular are fully capable of accommodating axial loads in both directions.
How to select the correct spherical roller bearing?
When selecting a bearing, the radial and axial loads, operating conditions, and mounting configuration must be taken into account. Detailed technical specifications are available in the spherical roller bearings catalog at the Marat store.
