Product Description
Features
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.
Bearings with cylindrical bore
Spherical roller bearings of all series are available with inner rings having a cylindrical bore.
Bearings with tapered bore
Spherical roller bearings are also available, with the exception of series 233..-A, with inner rings having a tapered bore.
Bearings with the suffix K have a bore taper 1:12, bearings of series 240 and 241 have a bore taper 1:30 and the suffix K30.
Bearings with adapter sleeve or withdrawal sleeve
Bearings with a tapered bore are also available with an adapter sleeve, locknut and tab washer or with a withdrawal sleeve.
Adapter and withdrawal sleeves must be ordered in addition to the bearing.
Sealing
We can by agreement supply sealed and greased bearings. Cages
The standard cages for spherical roller bearings are shown in the table and link.
