Abstract
A roller arrangement includes at least three parallel-axis rollers with a respective nip formed between adjacent rollers. Each of the rollers having a journal at both axial ends and is pivot-mounted via the respective roller journals. At least two bearings being arranged axially adjacent to one another at least on both of a first roller journal of a first, second and third adjacent rollers. A compressive stress is generated between an inner bearing on the first roller journal of the first roller and an outer bearing on the first roller journal of the second roller and a tensile stress is generated between an outer bearing on the first roller journal of the first roller and an inner bearing on the first roller journal of the second roller or vice versa. Similarly, compressive and tensile stresses are generated between the bearings on respective journals of the second and third adjacent rollers.
