Deep Groove Ball Bearings SKF 6005 /C3

The 6005/C3 deep-groove ball bearing, measuring 25x47x12 mm, offers increased clearance to accommodate thermal expansion in compact industrial drives.

The SKF 6005/C3 deep groove ball bearing is a single-row radial ball bearing made from standard rolling bearing steel (100Cr6) in the Explorer design. The bearing has a bore of 25 mm, an outside diameter of 47 mm and a width of 12 mm. As an open bearing without sealing rings, it is suitable for oil- or grease-lubricated installations within enclosed machine housings. The guided sheet steel cage maintains the rolling elements at a uniform distance.

What is the 6005 /C3 deep groove ball bearing suitable for?

This bearing primarily accommodates radial and moderate axial loads and operates in temperature ranges from -20 to +150 degrees. Thanks to its open design, the lubricant from the surrounding system reaches the raceways directly, which facilitates high operating speeds. Typical applications include rotating shafts and drives operating at elevated temperatures or higher speeds. In such applications, SKF’s Explorer design ensures smooth running under continuous load.

What are the advantages of C3 bearing clearance and tolerance class P6/P5?

The C3 designation indicates a slightly increased radial bearing clearance, which compensates for thermal expansion of the shaft or housing during operation. This ensures that the bearing clearance is maintained even when the bearing heats up, without causing stress on the rolling elements. Furthermore, this bearing has a dimensional accuracy of P6 and a running accuracy of P5. These tighter manufacturing tolerances ensure precise concentricity and reduced vibrations in demanding fits.
