Spherical roller bearings were initially used in applications where there were heavy loads, moderate speeds and the risk of misalignment. The application of these bearings has grown to include wind turbines, marine propulsion, sugar processing, pulp and paper production, material handling, mining and construction. Contributing to the growth of spherical roller bearings is the fact that they enable rotation with low friction and permit angular misalignment.
How the spherical roller bearing was invented
SKF engineer Arvid Palmgren is credited with the development of the spherical roller bearing. He joined SKF in 1917, taking a position in the company’s marketing department to work on technical information. Realizing that he lacked much of the background he needed to provide technical details, he set about working on bearing theory and started carrying out laboratory experiments.
