Deep Groove Ball Bearings SKF 6211 -2RS1/C3

The SKF 6211 -2RS1/C3 deep groove ball bearing combines the main dimensions 55x100x21 mm with a sealed design on both sides and increased C3 bearing clearance for industrial applications.

This single-row deep groove ball bearing 6211 -2RS1/C3 from SKF accommodates radial loads as well as axial forces in both directions. Both the raceways and the rolling elements are made from standard rolling-bearing steel 100Cr6. A robust sheet-steel cage guides the balls evenly along the raceway. The design is suitable for a temperature range of –20 to +120 degrees Celsius. The outer ring is manufactured without a flange or circumferential groove, which simplifies installation in cylindrical housing bores. It is manufactured to tolerance class P0/PN or ABEC 1, whilst the component has no electrical insulation.

What is the 6211-2RS1/C3 deep groove ball bearing suitable for?

The bearing is primarily used in industrial bearing arrangements where radial loads are combined with axial forces acting in both directions. With an inner diameter of 55 mm, an outer diameter of 100 mm and a width of 21 mm, this rolling bearing is suitable for applications involving continuous rotational movement on cylindrical shafts. The double-sided sliding seal is specially designed for environments where moisture, dust or fine particles may affect the bearing position.

What functions do C3 bearing clearance and the 2RS1 seal fulfil?

The suffix ‘C3’ indicates a slightly increased radial bearing clearance compared to the standard value. This additional radial clearance counteracts stress on the rolling elements when tight fits cause the inner ring to expand or when temperature differences occur between the inner and outer rings during operation. The 2RS1 seals, which seal on both sides, seal off the internal space, retain the lubricant inside the bearing and protect the component from particulate contamination from the outside.
