Complete Guide To Spherical Roller Bearing

 A spherical roller bearing is a spinning bearing that allows for low-friction rotation and angular misalignment. Spherical rollers’ rolling elements are primarily cylinder-like in shape, but they possess an authenticity that provides the appearance of slightly excessive cylinders. Spherical bearings are utilized in various industrial situations involving large objects, reasonable speeds, and the possibility of discrepancies. Gearboxes are a widely used software area—windmills made of wind.


Bearings With A Single Row Of Spherical Rollers (Barrel Bearing)

Many SR bearings have a row of rollers, permitting them to withstand extremely high radial. There are also designs for only one gearbox sequence suitable for low axial loading and practically no axial load. These are also understood as “barrel ball bearings” and “Tonnenlager” and are most typically observed within 202 and 203 sequences. Because ISO does not formalize the entire structure of both bearings, it varies from manufacturer and series.

Some characteristics that could or could not be present in various bushings are as follows:

  • Inner or outer ring lubrication features
  • Guide ring for the central flange or centre ring
  • Cage with integrated seals


Bearing rings and SR bearings are made from a wide range of materials, but the maximum common seems to be “chrome corrosion resistant,” that either contains 1.5% chrome. Several governments have enforced that “chrome steel,” resulting in a diverse range of taken forms. Bearing cages are commonly made from the following materials:

  • Steel sheet 
  • Polyamide 
  • Brass 
  • Steel 

The material is selected primarily according to the production volume and the method. Cages for high-volume bearings are frequently stamped sheet metal moulded polyamide, whereas cages for low-volume manufacturers are frequently machined metal or machined steel.


Here are the major advantages of using spherical roller bearing, which you must be aware of. Keep reading to know more here.

  • The dynamic load capacity has been raised by up to 25%.
  • Increasing the speed by up to 20%
  • Temperature range: up to 200°C
  • Up to a twofold increase in operating life
  • Maintenance cost reduction


Spherical roller bearings have been designed to handle high radial loads. They are also capable of sustaining some maximum load in either direction. They work well at medium speeds. Spherical raceways are found in the outer ring of spherical roller bearings for both rows of rollers. As a result, they self-align within broad boundaries and can tolerate minor misalignment.
