Deep Groove Ball Bearings SKF 6310 /C3

The SKF 6310/C3 deep groove ball bearing with a 50 mm bore offers increased radial clearance for industrial applications subject to thermal stress.

With the 6310 /C3 deep groove ball bearing, you are choosing a single-row rolling bearing from SKF that accommodates radial loads as well as axial forces in both directions. Manufactured from standard 100Cr6 bearing steel, the component has a bore of 50 mm, an outer diameter of 110 mm and a width of 27 mm. A sheet steel cage guides the rolling elements evenly into the deep raceways. As an open design without sealing washers, this bearing allows for the free circulation of externally supplied lubricants.

Under what operating conditions is the 6310 /C3 deep groove ball bearing required?

This deep-groove ball bearing is primarily used in bearing arrangements where there are significant temperature differences between the shaft and the housing. The open design requires a clean, protected housing environment, as no sealing elements are integrated at the factory. However, the design allows for free lubrication via external lubrication circuits or housing fillings. The permissible temperature range extends from –20 to +150 degrees Celsius for thermally stressed industrial applications.

What is the function of the C3 radial bearing clearance in this bearing?

The suffix C3 indicates a slightly increased radial clearance compared with the standard version. This internal clearance compensates for fit oversizes during press-fitting onto the shaft and for operational heating, ensuring that the rolling elements do not jam. When selecting a bearing, it is important to check whether the operating conditions generate elevated temperatures or involve tight fits. With tolerance class P0 or ABEC 1, the component meets common standard tolerances in mechanical engineering.
