Deep Groove Ball Bearings SKF 6207 /C3

The SKF 6207/C3 deep groove ball bearing, with dimensions of 35x72x17 mm, offers increased bearing clearance for thermally demanding radial and axial loads.

This single-row deep-groove ball bearing 6207 /C3 primarily accommodates radial forces and guides the shaft under combined loads. As an open rolling bearing without integrated sealing washers, it allows for easy lubricant passage during oil or grease lubrication. The rings and rolling elements are made from standard roller bearing steel 100Cr6, guided by a sturdy sheet steel cage. The component meets tolerance class P0/PN (ABEC 1) and is designed for a cylindrical fit on a 35 mm shaft.

What is the 6207/C3 deep groove ball bearing suitable for?

This radial ball bearing is primarily used in sealed housings that shield the bearing location from the outside environment. The open design allows for a continuous supply via an external lubrication circuit. Designs with a rotating inner ring benefit from the bearing’s low frictional resistance, as there are no abrasive sealing lips to cause drag. At the same time, the outer ring, which has no groove, evenly supports axial thrust forces in both directions.

How does C3 bearing clearance differ from the standard version?

The C3 designation indicates a slightly increased radial clearance compared with the standard version. This clearance is necessary if temperature differences occur between the inner and outer rings during operation, for example due to heating of the shaft. If the inner ring expands more significantly or if the installation requires tight fits, the increased radial clearance counteracts any straining of the rolling elements. This ensures that the bearing continues to run smoothly within the specified temperature range of -20 to +150 degrees.
