Spherical roller bearing 2 series

radialaxialdouble-row

Double-row spherical roller bearings are capable of capturing heavy radial load with simultaneous axial load in both directions. Large number of long, symmetrical barrels of a large diameter arranged in two rows with a common spherical raceway on the outer ring are typical for these bearings. The spherical shape of the raceway on the outer ring permits angular misalignment of the rings during operation and thus ensures even distribution of load on the rolling elements even with small shaft tilt or axial misalignment of the ring surfaces. These unique parameters help spherical roller bearings achieving: Lower operating temperatures and higher revolutions, Transmission of greater axial load, Longer lifespan The boundary dimensions of double-row spherical-roller bearings are specified in the dimension tables and they correspond to the international ISO 15 dimension requirements. The designation of bearings in the basic design is indicated in the dimension tables. The difference from the basic design is indicated by additional symbols.
