Toroidal roller bearings
BUT toroidal roller bearings (TORB) are single row pure radial roller bearings featuring slim symmetrical barrel rollers, which are properly profiled to give uniform stress distribution and proper roller/raceway contact. These properties keep at bay rolling friction and working temperature. Consequently, the lube film gap remains stable and the lubricant ageing process is slowed down, improving the application reliability. BUT toroidal roller bearings are conceived to be mounted as non-locating bearings, since they can face the thermal expansion along the shaft.
