Spherical Roller Bearings SKF 22219 E/C3

The SKF 22219 E/C3 spherical roller bearing can accommodate high radial loads with a 95 mm bore, 170 mm outer diameter and 43 mm width.

The SKF 22219 E/C3 self-aligning roller bearing is a double-row roller bearing designed for demanding industrial applications. It automatically compensates for misalignment and shaft deflection, as the barrel-shaped rollers can tilt on the spherical outer ring raceway. Manufactured from standard 100Cr6 rolling-element bearing steel, the unit withstands mechanical stresses within a temperature range of -30 to +200 degrees. As an open bearing, it can be integrated directly into existing lubrication systems.

What loads can the 22219 E/C3 self-aligning roller bearing accommodate?

This self-aligning roller bearing is particularly suitable for heavy-duty applications involving high radial forces and simultaneous shaft misalignment. Typical applications include situations where elastic deflection or misalignment between bearing positions needs to be compensated for.

Thanks to the guided sheet steel cage, the rolling elements maintain their defined position even under dynamic operating conditions. If misalignments occur due to housing deflection or assembly inaccuracies, the spherical internal geometry compensates for these deviations without causing excessive edge pressure.

What does the C3 bearing clearance mean for this self-aligning roller bearing?

The C3 designation indicates a slightly increased radial clearance compared with the standard version. This increased internal clearance helps to prevent the bearing from becoming stressed if the inner ring expands more than the outer ring due to operating heat, or if tight fits reduce the radial clearance.

In addition, the component features a lubrication groove with lubrication holes in the outer ring, which facilitates a continuous supply of lubricant. In terms of dimensional accuracy, the model complies with class PN, whilst the running accuracy of class P5 ensures smooth rolling behaviour.
