Introduction to Spherical Roller Bearings and their Mechanism

Spherical roller bearings have a spherical outer ring raceway in the outer ring. The spherical raceways of the inner and outer rings engage with a spherical roller. Spherical roller bearings can carry combined loads and can transmit axial and radial loads either separately or simultaneously. These bearings can be designed to withstand high radial loads, high axial loads or both simultaneously. In addition, these bearings have a very high capacity for handling misalignment. The spherical roller bearings are free rolling elements with a spherical outer ring raceway in the centre of the bearing. They are intended to be mounted between two shafts which have a close running fit on the inner and outer rings. The rollers bear on the spherical raceways of the inner and outer rings, respectively. The spherical roller bearings can accommodate combined misalignment and angular movement in one direction. However, they cannot absorb any misalignment nor angular movements which are present in more than one direction.It is very important to choose the right bearing manufacturing company for all your bearing solutions.


Spherical roller bearings are used to guide or support rotating or reciprocating shafts. The bearing consists of two rows of cylindrical rollers that are supported by the cage on both sides. The rollers are round sections made of chrome steel with balls running on their outer surface. The axes of the rollers are mutually perpendicular and form an angle of 30 degree with the plane formed by the axes of the shafts. There are several different types of bearings. They range from simple rolling-element bearings to the extremely complicated spherical roller bearings mechanism. Generally, different types of bearings are used depending on the application and machinery is very important for supporting infrastructure. Rotating element bearings are stationary in the direction of the shaft’s rotation, but they rotate along with it. They are used to convert either rotational or linear motion into the other. The most common types of rotating element bearings are ball, cylindrical roller, needle roller, tapered roller, spherical roller, and sleeve bearing.We should also know the importance of dust lip seal in running the bearings effectively.
