Thick outer ring walls are able to withstand high radial loads while reducing deformation and bending stresses. Due to their ribs on the inner ring, the support roller units can also withstand heavy axial loads.
The maximum number of rollers in double- and four-row cylindrical roller bearings without cage contributes to high load-carrying capacities.
The surface finish on the contact surfaces of the rollers and raceways as well as the optimized internal geometry of these roller units can help to maintain very low levels of friction during start-up and operation.
The logarithmic curve profile reduces edge stresses at the roller/raceway contact.
