SKF CARB toroidal roller bearings
SKF CARB bearings permit smaller and lighter bearing arrangement designs offering the same or improved performance in a particularly impressive manner, e.g. in planetary gearboxes. They simplify the bearing arrangement design for long shafts that are subjected to temperature variations. When using SKF CARB bearings, it has also been proven that vibration levels are reduced, e.g. in paper machines or fans.
The double lip seal, suitable for high temperature operations, is sheet steel reinforced and made of hydrogenated-acrylonitrile butadiene rubber (HNBR). It seals against the inner ring raceway. The outside diameter of the seal is retained in an outer ring recess and provides proper sealing also in applications with outer ring rotation. The seals can withstand operating temperatures in the range of –40 and +150 °C.
