Tips for Roller Bearings

How do Spherical Roller Bearings Work?

The best option for applications that require shock-resistant components is a spherical roller bearing, but this is not their only advantage. These Bearings can support enormous weights due to the alignment of their rings. Due to the curved outer ring, spherical bearings have the ability to self-align, which allows them to sustain heavy axial and radial loads even in unfavourable conditions with a lot of vibration.

The operating principle for all spherical roller bearings is the same. All of them feature concave (spherical) inner raceways in their outer rings. Similar convex outer raceways (or rolling components that provide a comparable convex sliding surface) can be found on the inner rings. The layout of their sliding surface is what distinguishes the numerous spherical bearing types. Some use rolling components like balls or rollers between the inner and outer rings, while others use ring-to-ring construction (such spherical plain bearings and rod ends).

Types of Spherical Roller Bearings

Spherical Roller Bearings:

They are made to function in settings with serious misalignment. This can be caused by a shaft deflection or an installation issue. They deal with some axial loads in either direction and relatively heavy radial loads. Additionally, they have a high level of shock resistance, and their self-aligning characteristic enables full capacity loading even with shaft deflection. Self-Aligning Double Row Ball Bearings serve a similar function, but Spherical Roller Bearings are stronger since they can support higher loads at slower maximum speeds.

Spherical Plain Bearings:

(sometimes referred to as "Spherical Plane Bearings") are spherical bearings that have an outer ring with a concave inside surface that corresponds to a sphere's convex outside surface on the inner ring. They are especially well suited for bearing arrangements where oscillating or recurrent tilting motions must be allowed at relatively slow sliding rates, or if alignment movements between the shaft and housing must be accommodated.

Spherical Rod End Bearings:

An eye-shaped head with an integral shank forming a housing, a normal spherical plain bearing, or a spherical plain bearing inner ring make up this kind of spherical bearing. They are used at the ends of rods, as their name suggests, and have either a male or female thread for mounting.
