Spherical roller bearing with tapered bore and relubrication features
Spherical roller bearings can accommodate heavy loads in both directions. They are self-aligning and accommodate misalignment and shaft deflections, with virtually no increase in friction or temperature. The design includes features to facilitate relubrication. The bearings can be used in a modular system, including housings, sleeves and nuts.

Four-row tapered roller bearing
Four-row tapered roller bearings can accommodate combined heavy radial and axial loads at low to moderate speeds. They are used almost exclusively in work roll applications such as rolling mills. SKF manufactures four-row tapered roller bearings in TQO and TQI designs, in many variants and with different features.
Very high radial load carrying capacity

7309 BEP
7309 BEP - Angular contact ball bearings
Image may differ from product. See technical specification for details.
Single row angular contact ball bearing
These single row angular contact ball bearings can accommodate radial and axial loads acting simultaneously, where the axial load acts in one direction only. They can operate at high speeds and, depending on the variant, even very high speeds. They are more suitable than deep groove ball bearings for supporting large axial forces acting in one direction.
High-speed capability
Accommodate relatively high radial loads and large unilateral axial loads
