Deep Groove Ball Bearings SKF 6226 /C3

The SKF 6226/C3 deep groove ball bearing, with a 130 mm bore and increased bearing clearance, offers stable operation under thermal loads.

This single-row deep groove ball bearing 6226/C3 from SKF is designed for predominantly radial loads and also accommodates axial forces in both directions. Manufactured from standard rolling-element bearing steel 100Cr6 and fitted with a dimensionally stable sheet steel cage, the component operates within a temperature range of -20 to +150 degrees Celsius. The open design, without sealing washers, allows for direct circulation of lubricating oil or grease within the bearing housing.

What are the industrial applications for the 6226/C3 deep groove ball bearing?

This size is generally used in mechanical engineering for shaft bearing seats with a diameter of 130 mm and high radial loads. As the outer ring is cylindrical with no flange or groove, the bearing can be fitted precisely into corresponding housing bores. This design is suitable for applications where guidance of the rotating components and smooth running are required.

What is the function of the C3 clearance in the 6226 deep groove ball bearing?

The designation C3 indicates an increased radial clearance compared with the standard version. This increased clearance between the balls and raceways compensates for thermal expansion when temperature differences occur between the inner and outer rings during operation. Furthermore, the C3 clearance helps to prevent the rolling elements from becoming stressed in the case of tight fits. The bearing complies with tolerance class P0/PN (ABEC 1) for standard mounting conditions.
