Deep Groove Ball Bearings SKF 6003

The SKF 6003 deep-groove ball bearing, measuring 17x35x10 mm, offers compact dimensions, an open design and enhanced running accuracy for demanding industrial applications.

The SKF 6003 single-row deep groove ball bearing is one of the tried-and-tested rolling bearings for rotating shafts. As an open design without integrated sealing washers, this bearing allows for the direct supply of lubricating oil or grease via the surrounding system. SKF’s Explorer design is based on an optimised internal geometry made from standard roller bearing steel (100Cr6). Together with a sheet steel cage, the bearing accommodates predominantly radial loads as well as moderate axial loads in both directions.

In which designs is the open deep-groove ball bearing 6003 used?

The open deep-groove ball bearing 6003 is primarily fitted in enclosed assemblies where housing seals prevent the ingress of dirt or moisture. Typical applications include oil- or grease-lubricated bearing locations in rotating machine components. By eliminating sliding seals, the bearing reduces friction losses, which has a positive effect on heat generation and limiting speeds. The permissible temperature range is from –20 to +120 degrees Celsius.

What is the function of tolerance classes P6 and P5 in the 6003 model?

In the 6003 model, SKF combines dimensional accuracy to P6 with running accuracy to P5. These tighter tolerances compared with the standard specification reduce runout errors and promote smooth shaft rotation. When designing the bearing seats, it is advisable to manufacture the mating surfaces to a correspondingly high degree of precision in order to make full use of the clearance. With the standard radial bearing clearance, the rolling bearing is suitable for standard fits without any exceptional temperature differences between the inner and outer rings.
