Deep Groove Ball Bearings SKF 6206 -2RS1/C3

The SKF 6206 -2RS1/C3 deep groove ball bearing is a double-sealed rolling bearing with dimensions of 30 × 62 × 16 mm and increased bearing clearance.

The 6206 -2RS1/C3 deep groove ball bearing is a single-row radial ball bearing made from standard bearing steel (100Cr6) with a cylindrical bore. Fitted with seals that run against the bearing on both sides, the design protects the bearing interior from dirt and moisture and retains the factory-applied grease inside the bearing. Thanks to its compact main dimensions – with an inner diameter of 30 mm and an outer diameter of 62 mm – this design can handle radial forces as well as moderate axial forces in both directions.

For which operating conditions is the 6206-2RS1/C3 deep groove ball bearing suitable?

Typical applications are found in general mechanical engineering on rotating shafts. Design engineers use this variant primarily where ambient dust or splashing water is present and manual relubrication needs to be avoided. Thanks to its robust sheet steel cage and the permissible temperature range of –20 to +120 degrees Celsius, this rolling bearing is suitable for standard industrial operating conditions. The smooth outer ring without a groove facilitates standardised housing installation.

What do the designations 2RS1 and C3 mean in terms of operation?

These suffixes denote specific functional characteristics for demanding installation conditions. The designation 2RS1 stands for two sealing lips that come into contact directly with the inner ring, forming an effective barrier. The designation C3 describes a slightly increased radial bearing clearance compared with the standard version. This additional internal clearance compensates for operational thermal expansion of the shaft or housing stresses in fixed fits, thereby preventing the rolling elements from becoming jammed.
