Spherical Roller Bearings

Spherical roller bearings use rollers that are thicker in the middle and thinner at the ends; the race is shaped to match. Spherical roller bearings can thus adjust to support misaligned loads. However, spherical rollers are difficult to produce and thus expensive, and the bearings have higher friction than a comparable ball bearing since different parts of the spherical rollers run at different speeds on the rounded race and thus there are opposing forces along the bearing/race contact.

Self aligning Spherical Roller Bearing consists of a spherical outer race and inner race with two tracks, a cage and a complement of spherical shaped rollers.

Just like double row self-aligning ball bearings these bearings too are not sensitive to

misalignment and it can adjust itself to shaft deflections.

The design of this bearing permits radial load and heavy thrust load in either direction.
