Product Description:
Spherical roller bearings are a type of rolling bearings that have the ability to withstand large radial loads and certain axial loads. These bearings are designed with centers of the inner and outer rings that can be tilted to the axis, which allows them to automatically align their centers.
Unlike other types of bearings, spherical roller bearings have double-row rollers and a commonly spherical raceway on the outer ring. Meanwhile, two raceways on the inner ring are also tilted at an angle relative to the bearing axis. The unique design of these bearings enables them to adjust the axis misalignment caused by the deflection or non-concentricity of the shaft or housing.
Thanks to their excellent aligning performance, spherical roller bearings are highly sought-after in industrial applications where there are significant variations in the shaft or housing deflection. Overall, these bearings offer a reliable and efficient solution for applications in which there are high loads and a need for accurate alignment.
Features:
Automatic Self-Aligning Property
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.
High Load-Bearing Capacity
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.
Good Impact Resistance
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.
Strong Applicability
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.
Smooth Operation
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.
Easy Maintenance
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.
