Overview

Single-row spherical roller bearings (SRR) are rolling bearings that can withstand both radial and axial loads. The inner and outer raceways are spherical in design and have an automatic self-aligning function, which can effectively cope with shaft offset or installation deviation, ensuring stable performance, making them an ideal choice for a variety of industrial applications.

Core features

Automatic self-aligning function: The spherical raceway design can compensate for the angular deviation between the shaft and the bearing seat, reducing the risk of failure caused by installation errors or shaft deformation.

  • High load capacity: It can withstand large radial loads and support medium axial loads in both directions.
  • Excellent durability: The structure is strong and the service life is long, suitable for heavy loads and high-intensity conditions.

Application areas

Single-row spherical roller bearings are widely used in the following scenarios:

  • Motors: Suitable for high-power industrial motors, especially large equipment that needs to withstand both radial and axial loads.
  • Metallurgical equipment: Used in machinery such as mills, crushers and conveyors, and can cope with heavy loads and shock loads.
  • Mining machinery: Effectively handle high radial loads and vibrations in equipment such as crushers, screens and conveyors.
  • Wind power generation: used in wind turbine generators to support the high loads generated by the blades.
  • Construction equipment: suitable for heavy machinery such as cranes and excavators, which can withstand high radial and axial loads.
  • Transportation equipment: used in railway and automobile wheels, axles and other components to meet high load and durability requirements.
