Complex inner geometry has prevented many companies within the bearing industry, from producing toroidal roller bearings, this is not the case for Swiss manufacturer, RKB Bearings.
Since the 1990s, RKB has manufactured a type of Toroidal Bearing called ‘TORB’. They are most commonly used in the steel and paper industry for continuous casting machines and calendars.
Toroidal bearings are used in the presence of high radial load which can tolerate significant misalignments. This particular bearing is typically installed as non-locating bearings because they are able to withstand a very large axial thermal expansion.

Since 1936, RKB has been manufacturing products in the bearing industry, producing over 350 tons of machined steel. With a network of distributors that stretches worldwide, they are able to export their products to over 50 countries.
