SKF Bearings - Bearing Parts & Supplies - Grainger .
Axial (thrust) bearings support loads parallel to the axis of the shaft, such as those exerted by a table supporting a weight. Radial bearings support rotating wheels and other applications where the force of the load is perpendicular to the shaft. Ball bearings are used with applications that have high axial loads and low-to-moderate radial loads.
SKF Deep Groove Ball Bearing, Double Sealed, Steel Cage .
The SKF deep groove ball bearing is a double-sealed ball bearing with C3 clearance and has a deep-groove geometry for high speeds and supporting both radial and axial loads. This bearing has C3 radial internal clearance for radial slack between the inner and outer rings that is greater than CN (normal) to compensate for thermal expansion.
