  Spherical roller bearings are double row, self  retaining units comprising solid outer rings with a concave raceway, solid inner rings and barrel rollers with cages.

 The inner rings have cylindrical or tapered bores.

 The symmetrical barrel rollers orient themselves freely on the concave outer ring raceway. As a result, shaft flexing and misalignment of the bearing seats are compensated, see link.

 Many sizes of spherical roller bearings are of an X-life design.

 These bearings have improved kinematics and optimised surfaces, are made from higher performance materials and do not have a rigid central rib.

 As a result, the basic dynamic load rating and, under identical operating conditions, the basic rating life of the bearings is significantly improved. In certain applications, this means that a smaller bearing arrangement can be designed.

 X-life spherical roller bearings have the suffix E1 and are indicated in the dimension tables.

Radial and axial load capacity

 Spherical roller bearings can support axial forces in both directions and high radial forces. They are designed for very high load carrying capacity and, since they have the maximum possible number of large and particularly long barrel rollers, are also suitable for the heaviest loads.

 Due to the narrow osculation between the rollers and raceways, uniform stress distribution is achieved in the bearing.

Compensation of  angular misalignments

 Spherical roller bearings compensate for angular misalignments. The permissible adjustment angle is stated for loads P < 0,1 · Cr,    

 These adjustment angles are permissible if

 the angular deviation is constant (static angular misalignment)

 the rotating component is the inner ring.

 Reduced adjustment angle

  If the rotating component is the outer ring, the inner ring undergoes tumbling motion or the adjustment angles are larger than stated in the table, the angular adjustment facility is smaller.

  If such applications are present, please contact us.
