Toroidal rolling bearings with angular adjustment capability

The FAG TORB range of toroidal rolling bearings is manufactured to Schaeffler’s premium quality X-life standard. The bearings are single row rolling bearings with long, slightly spherical rollers, enabling the FAG TORB to combine the angular adjustment capabilities of a spherical roller bearing with the axial displacement capabilities of a cylindrical or needle roller bearing. This means the bearings are suitable for a variety of industrial applications, including steel rolling mills (e.g. continuous casting plants), belt and conveyor systems, paper machines (e.g. drying cylinders), marine drives, turbomachinery used in power generation (e.g. ventilators), textile machines, crushers, food processing machines, and agricultural machinery.

FAG TORB toroidal rolling bearings are available in two versions: as full complement bearings or as a caged version. When the design envelope is restricted, the caged bearing provides very high radial load carrying capacity, even when skewing or axial displacements need to be compensated for. The full complement bearing offers a particularly high load carrying capacity.

Schaeffler (UK) says the FAG TORB bearings allow the operational reliability and cost-effectiveness of locating/non-locating bearing supports to be significantly increased.

Temperature-related linear expansion and misalignments mean that non-locating bearing designs are particularly important. FAG TORB bearings are a suitable non-locating bearing for use in combination with a spherical roller bearing as the locating bearing, allowing either higher load ratings or a smaller design envelope to be achieved.

FAG TORB toroidal rolling bearings compensate for large axial linear expansion between the raceways and rolling elements in the bearing. Even when greater axial displacement occurs, the load is still distributed symmetrically to the roller rows in the (locating) spherical roller bearing. FAG TORB bearings also dampen the axial vibrations of the entire bearing system, reducing the stress on the spherical roller bearing, which in turn positively influences the operating life of the entire bearing system.

Complete interchangeability with previous bearing designs is also provided, as FAG TORB bearings are manufactured to the same ISO dimensions as spherical and cylindrical roller bearings that are used as non-locating bearings.
