Spherical Roller Bearings

Spherical Roller Bearings

Spherical roller bearings have an inner ring with two raceways and a spherical raceway in the outer ring. They also have spherical rollers, cages, and some with rings which provides a design for self-aligning. The self-aligning feature permits a full capacity loading despite any shaft deflection. The two rows of rollers allow for a heavy radial and modest axial load operating at moderate speeds. Spherical roller bearings are dedicated specifically to extremely severe applications for support of high load, misalignment, contaminated environments, shock and vibration. They are often used in aerospace transportation, high-tech mining, agriculture, construction, food processing, and heavy equipment. The following are some key considerations and benefits of spherical roller bearings:

  • Accommodate misalignment
  • Low friction
  • Long service life
  • High load-carrying capacity
  • Low maintenance/operating costs
  • Pre-lubricated and sealed-enables easy mounting

The size and width of spherical roller bearings can vary according to their use and application. They are similar to self-aligning double row bearings except spherical roller bearings are designed with the intent to carry heavier loads but at lower maximum speeds. These bearings are made to be non-separable and come in various applications. They are usually made from chrome steel with cages. Spherical roller bearings have roller that are spherical in shape compared to the more regular ball shape. The design of these bearings also is permit greater angular misalignment than other cylindrical bearings.
