Self-aligning thrust roller bearings

Spherical roller thrust bearings ISB spherical roller thrust bearings are designed in such a way that the load is transmitted from one raceway to the other at a certain angle compared to the bearing’s axis.

This features means that these bearings are able to with stand axial loads acting simultaneously with radial loads.
They are self-aligning and consequently insensitive to shaft deflections and shaft misalignments compared to the housing.
ISB spherical roller thrust bearings are able to withstand very high axial loads and high operating speeds. They have a largenumber of asymmetric rollers and the special design of the raceways enables optimum conformity.
The overall dimensions of the ISB® spherical roller thrust bearings comply with standard ISO 104:2002.
ISB spherical roller thrust bearings are usually manufactured with Normal tolerances, according to standard ISO 199:1997.
Seeing as they are self-aligning, the misalignment of the shaft compared to the housing and also shaft deflections are tolerated . The possibility to fully exploit this misalignment depends on the type of bearing and the seal.
