Spherical Roller Bearings

Overview

Spherical Roller Bearings
Spherical Roller Bearings also known as Self aligning roller bearings are a type of rolling bearing with spherical raceways and double rows of rollers. They can withstand high radial and bidirectional axial loads. The unique spherical raceway design provides self-aligning capabilities, which can compensate for installation errors and shaft deflection. These bearings maintain low friction and heat levels even at high operating speeds. roller spherical bearing come in various types, including asymmetrical rollers, symmetrical rollers, and tapered bore designs.

Single Row Spherical Roller Bearing

Spherical Roller Bearings

Single-row spherical roller bearings are a type of rolling bearing with a spherical raceway and a single row of rollers. These bearings offer several advantages, including the ability to withstand high radial loads and certain axial loads. The spherical raceway design provides self-aligning capabilities, allowing the bearing to compensate for installation errors and shaft deflection.

Features:

  • Self-Aligning:
    Due to the spherical raceway design, these bearings can automatically adjust alignment, compensating for installation errors and shaft deflection, ensuring smooth operation.

  • High Radial Load Capacity:
    The single-row design allows the bearing to withstand extremely high radial loads, making it suitable for heavy-duty applications.

  • Impact and Vibration Resistance:
    With high rigidity and strength, these bearings can endure impact loads and vibrations, making them ideal for harsh working conditions.

The parameters in the table represent different series and types of spherical roller bearings. The main differences lie in the cage materials and designs (CA, CC, HQCC), the range of inner diameters, and the variant structures (K / W33). These parameters determine the bearing’s load-carrying capacity, applicable range, and performance characteristics.

Single-row spherical roller bearings, due to their self-aligning capabilities, high radial load capacity, and resistance to impact and vibration, are widely used in mining equipment, heavy machinery, industrial equipment, the paper industry, and the steel industry.

Double Row Spherical Roller Bearing

Double Row Spherical Roller Bearing
Double-row spherical roller bearings are rolling bearings designed to withstand high radial loads and bidirectional axial loads. Their spherical raceway and double-row roller design provide self-aligning capabilities, allowing them to compensate for installation errors and shaft deflection.

Features:

  • Self-Aligning Function:
    The raceways of both the inner and outer rings are spherical, allowing the bearing to automatically adjust alignment during operation, compensating for deviations caused by shaft deflection and installation errors.

  • High Radial and Axial Load Capacity:
    The double-row design provides extremely high radial load capacity and can also withstand bidirectional axial loads.

  • Impact and Vibration Resistance:
    Due to their high rigidity and strength, double-row spherical roller bearings can endure impact loads and vibrations, ensuring smooth operation.

FAQs

The self-aligning function allows the bearing to automatically adjust itself during operation, compensating for deviations caused by installation errors or shaft deflection. This ensures smooth operation and extends the bearing's lifespan.

To ensure the long lifespan and high performance of spherical roller bearings, regular maintenance and proper lubrication are necessary. Common lubrication methods include grease lubrication and oil lubrication. Regularly check the lubrication condition of the bearings, ensuring the lubricant is clean and sufficient, which can significantly extend the bearing's service life.

Yes, spherical roller bearings can be used in both high-temperature and low-temperature environments. Selecting appropriate materials and lubricants ensures good performance and long service life under extreme temperature conditions.
