Design Principles

The design principle of spherical roller bearings involves using two rows of rollers with a common spherical outer raceway, which allows the bearing to self-align when there is misalignment or bending of the shaft. The inner ring has two raceways that are inclined at an angle to match the spherical outer raceway. This design allows the bearing to tolerate misalignment and bending of the shaft, and to carry loads in multiple directions.

Performance Features

The performance features of spherical roller bearings include:

• Self-aligning capability: Able to automatically adjust to misalignments or deviations of the shaft, reducing stress concentrations.
• Combined load capacity: Capable of carrying high radial loads and significant axial loads simultaneously.
• Adaptability to different working conditions: Can accommodate shaft deflection and improper mounting, as well as shaft movement during operation.
• Durability: Performs well under conditions of vibration or impact loads.
• Separability: Some designs allow the inner and outer rings to be installed and removed separately.

Application Scenarios

Spherical roller bearings are suitable for a variety of scenarios, including:

• Heavy industry: Such as in paper-making machines, heavy-duty reducers, rotary kilns, and crushers.
• Mining and construction: Widely used in excavation machinery, cranes, and bridge supports.
• Wind power generation: Frequently used in the main bearings of wind turbines.
• Maritime: In ship propulsion shafts and deck machinery.
• Bearing housings and self-aligning bearing housings: Provide shaft alignment in bearing housing applications.
