Deep Groove Ball Bearings SKF 6015 /C4

The SKF 6015/C4 deep groove ball bearing, with dimensions of 75x115x20 mm and a C4 clearance, offers reliable operation under thermal loads.

This single-row deep groove ball bearing 6015/C4, part of the SKF Explorer performance class, accommodates both radial and axial forces in both directions. The open design allows for direct lubrication via the housing system. Manufactured from standard rolling-element bearing steel (100Cr6) with a robust sheet steel cage, the design covers a temperature range from –20 to +150 degrees. With dimensional accuracy to tolerance class P6 and normal running accuracy PN, the component is suitable for precisely guided shafts in industrial machinery.

What is the 6015/C4 deep groove ball bearing suitable for in operation?

Design engineers primarily use this rolling bearing where high operating temperatures or temperature differences between the inner and outer rings occur. Heat usually causes the shaft to expand more than the surrounding housing. The single-row radial ball bearing compensates for such expansion without causing harmful stress in the rolling elements. Typical applications include industrial assemblies subject to high thermal loads, as well as bearing locations operating at high speeds.

What are the advantages of C4 radial clearance in this rolling bearing?

The designation C4 indicates a significantly increased radial clearance, which exceeds the normal operating clearance. This increased radial clearance counteracts the bearing becoming jammed when heated or in the case of tight fits. As this is an open design without integrated sealing washers, the installation location requires an external housing seal to protect against dirt and moisture. This allows the supply of grease or lubricating oil to be precisely tailored to the respective maintenance interval.
