Spherical Roller Bearings SKF 22211 E

The SKF 22211 E spherical roller bearing, measuring 55x100x25 mm, offers a high load-carrying capacity and automatically compensates for angular misalignment during operation.

The 22211 E self-aligning roller bearing is a double-row roller bearing from SKF in the Explorer series, designed for demanding industrial applications. With a bore of 55 mm, an outer diameter of 100 mm and a width of 25 mm, the bearing can withstand high radial loads as well as axial loads on both sides. The open design, made from standard 100Cr6 rolling-bearing steel, features a robust sheet-steel cage. Thanks to the spherical outer ring raceway, this bearing compensates for misalignment or shaft deflection.

In which applications is the 22211 E self-aligning roller bearing used?

The 22211 E self-aligning roller bearing is primarily used in shaft mountings subject to high radial forces and operational deflection. The spherical raceway in the outer ring enables the compensation of static and dynamic misalignments without unnecessarily increasing friction. The component is therefore suitable for heavy-duty industrial applications involving rotating shafts and combined loads.

In such environments, the roller guide absorbs shock loads. As the bearing is designed for operating temperatures ranging from -30 to +200 degrees, it is suitable for thermally demanding conditions in industrial machinery.

What are the advantages of the lubrication groove and P5 running accuracy?

The lubrication groove with lubrication holes in the outer ring simplifies regular maintenance. It directs grease or lubricating oil directly between the two sets of rollers, ensuring a consistent supply of lubricant. The P5 running accuracy, compared to the standard PN dimensional accuracy, ensures low-vibration concentricity at higher speeds. When designing the system, it should be noted that this open bearing requires a housing seal to be fitted on site to prevent the ingress of contaminants.
