Abstract

An angular contact self-aligning toroidal roller bearing comprising an inner ring, an outer ring, and a set of rolling elements formed of rollers arranged in an intermediate configuration between the inner and outer rings. Each roller is arranged to self orient in its axial direction in relation to the inner and outer rings in a loaded zone during operation. Furthermore, a method for determining dimensional parameters of structural members of an angular contact self-aligning toroidal rolling element bearing and a method for manufacturing an angular contact self-aligning toroidal rolling element bearing are described herein.
