Spherical roller bearings are a type of rolling bearings widely used in industry due to their ability to withstand large radial loads and certain axial loads. They have a unique design that allows them to automatically align their centers, thanks to the centers of the inner and outer rings that can be tilted to the axis. This feature distinguishes them from other types of bearings, making them ideal for applications that require high accuracy and reliable performances.
Unlike other rolling bearings, spherical roller bearings have double-row rollers and a commonly spherical raceway on the outer ring. The two raceways on the inner ring are also tilted at an angle relative to the bearing axis, making them able to adjust the axis misalignment caused by the deflection or non-concentricity of the shaft or housing.
The excellent aligning property of spherical roller bearings makes them highly sought-after in industrial applications where there are significant variations in the shaft or housing deflection. Hence, they offer a reliable and efficient solution for applications in which there are high loads and a need for accurate alignment.
The spherical roller bearing is designed with a spherical raceway between the inner and outer rings. This design allows the bearing to have automatic self-aligning ability, meaning that it can adjust the deviation of the axis and maintain stable operation even if the shaft or housing is deflected or not concentric.
As a result, installation accuracy requirements are greatly reduced, and the service life of the bearing is prolonged.
The double-row roller structure and the spherical raceway design between the inner and outer rings enable the spherical roller bearing to withstand large radial loads and certain axial loads. This design effectively disperses the load and reduces stress concentration of the bearing, ensuring stable operation even when bearing heavy loads.
The automatic self-aligning and high load-bearing capacity of the spherical roller bearing provide good stability and durability when bearing impact loads. This feature makes it particularly suitable for mechanical equipment requiring to withstand impact loads.
The inner hole of the spherical roller bearing is cylindrical and conical. The tapered inner hole bearing is equipped with a tightening sleeve or a withdrawal sleeve, which can be easily assembled on the smooth shaft or the stepped machine shaft.
This design enables the spherical roller bearing to adapt to a variety of installation requirements and improves its applicability.
The spherical roller bearing can maintain a stable state during operation, reducing vibration and noise. This helps to improve the operating efficiency and service life of mechanical equipment, while also reducing noise pollution to the surrounding environment.
The spherical roller bearing is easy to maintain as it has a relatively simple disassembly and installation process. When replacement or maintenance is required, it can be disassembled and installed quickly, reducing downtime and maintenance costs.

Spherical roller bearings have proven to be crucial components in various industrial areas and equipment, including ships, textiles, mills, electricity, washing equipment, and transmission gearboxes. Their widespread application is due to their exceptional self-aligning ability, huge load capacity, and excellent stability.
These properties enable spherical roller bearings to adapt to complex industrial environments and play vital roles in multiple industrial fields. Being self-aligning means they can adjust to misalignment issues, making them suitable for machinery that operates in harsh conditions.
Spherical Roller Bearings are designed to accommodate heavy radial loads, as well as axial loads in both directions. They are self-aligning bearings that can compensate for misalignment caused by shaft deflection or housing deformation. These bearings are commonly used in applications such as mining equipment, paper mills, and vibrating screens.
