Description
Spherical roller bearings
Spherical roller bearings have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis (
fig. 1.) The centre point of the sphere in the outer ring raceway is at the bearing axis. Therefore, the bearings are self-aligning (
fig. 2) and insensitive to misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection. Spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both
Bearing performance is not only determined by load or speed ratings. There are a number of other factors that contribute to bearing performance. To a large extent, performance is influenced by the geometry of the rollers, raceways and cages, the heat treatment, as well as the surface finish of all contact surfaces.
Why spherical roller bearings?
Spherical roller bearings offer an attractive
combination of design features, which are
making them irreplaceable in many demanding
applications.
• Self-aligning
Spherical roller bearings accommodate misalignment between the shaft and housing without increasing friction or reducing bearing service life.
• Very high load carrying capacity Optimized internal geometry within the available cross section provides maximum
radial and axial load carrying capacity.
• Robust:
Insensitive to misalignment caused by shaft or housing deflections as a result of heavy loads.
• Easily fitted for loads in all directions The bearings are non-separable and readyto install, having a choice of mounting methods.
• Simplify the application
The favourable design characteristics combined with simplified mounting procedures enable more efficient and compact machine designs.
