Self aligning needle roller bearings
The static self aligning needle roller bearings comprise a massive outer ring with a spherical surface, covered in a sheet metal jacket that is supported by two PTFE rings with a concave profile. The needle cage is retained in the outer ring. The inner ring is without ribs. The bearing is non-locating and can only carry limited axial displacements. It is used in applications where static misalignment of the shaft up to 3 ° is required.
