Deep Groove Ball Bearings SKF 6011 -2RS1/C3

The SKF 6011 -2RS1/C3 deep groove ball bearing combines contact seals with increased bearing clearance whilst maintaining compact overall dimensions of 55 × 90 × 18 mm.

The SKF 6011 -2RS1/C3 single-row deep groove ball bearing is designed primarily to support radial loads as well as axial forces in both directions. Manufactured from standard rolling-element bearing steel (100Cr6) in the Explorer design, this variant features a sheet steel cage. A cylindrical outer ring without a flange or groove allows for direct installation in standardised housing bores. Thanks to the factory-fitted seals, the unit is protected against foreign matter during operation.

What is the 6011-2RS1/C3 deep groove ball bearing suitable for?

Design engineers and maintenance personnel use this version primarily in rotating assemblies operating at moderate to high speeds that are subjected to combined loads. The sealing lips, which make contact on both sides, keep dirt particles and splash water away from the raceway system. Thanks to the increased bearing clearance (C3), smooth running is maintained even when thermal expansion of the shaft or housing reduces the radial clearance during operation.

What are the advantages of combining the 2RS1 with C3 bearing clearance?

The seal designation 2RS1 denotes two sealing discs in contact with one another, which lie flush against the inner ring and form a protective barrier against environmental influences. The suffix C3 indicates a slightly increased radial bearing clearance compared with the standard version. This clearance helps to prevent stress on the rolling elements when tight fits are used or when temperature differences arise between the inner and outer rings during continuous operation. Together with tolerance class P6 or ABEC 3, this ensures low-vibration operation.
