Deep Groove Ball Bearings SKF 6201 /C3

The SKF 6201/C3 deep-groove ball bearing, with dimensions of 12x32x10 mm, increased C3 clearance and high running accuracy, offers reliable performance for precise industrial shaft mountings.

This single-row deep-groove ball bearing 6201/C3 from SKF accommodates radial forces as well as axial loads in both directions. The open design allows for direct lubrication via the surrounding housing system, whilst the robust sheet steel cage maintains an even spacing between the rolling elements. Manufactured from standard 100Cr6 bearing steel in the SKF Explorer design, the bearing reliably operates over a wide temperature range from -20 to +150 degrees.

What is the 6201/C3 deep groove ball bearing suitable for in operation?

Designs with externally lubricated bearing housings frequently utilise this design for rotating shafts, gearboxes or electric motors. As the open bearing does not feature integrated sealing discs, it operates without additional friction losses caused by sealing lips in the oil or grease bath of the housing environment. Thanks to the combination of dimensional accuracy to Class P6 and increased running accuracy to Class P5, the component is suitable for units where low vibration and precise concentricity are required.

What is the function of the increased C3 bearing clearance?

The C3 specification denotes a slightly increased radial bearing clearance when the bearing is new. This additional radial clearance compensates for operational thermal expansion when the inner and outer rings reach different temperatures during operation. Furthermore, the C3 bearing clearance compensates for the radial constriction of the raceways in the case of tight fits on the shaft or in the housing. The use of this variant serves to effectively prevent excessive stresses in the rolling element set under thermal loading.
