Why spherical roller bearings?
Spherical roller bearings offer an attractive combination of design features, which are making them irreplaceable in many demanding applications.
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.
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 ready to install, having a choice of mounting methods.
SKF bearings are developed for customer satisfaction. The best confirmation of the total quality of SKF spherical roller bearings is their success on the market. There are twice as many SKF spherical roller bearings in service as those of any other bearing manufacturer. This is not just by chance: SKF spherical roller bearings are well-proven in the field and undergo continuous development to provide improved performance. The latest examples include the introduction of SKF Explorer bearings, which opened up new application horizons.
