Spherical Roller Bearings SKF 22216 E/C3

The SKF 22216 E/C3 spherical roller bearing, with dimensions of 80x140x33 mm and a C3 clearance, offers high load-carrying capacity in the face of shaft deflection and misalignment.

The 22216 E/C3 self-aligning roller bearing is designed for demanding mechanical loads in continuous industrial operation. Thanks to its barrel-shaped rollers, this bearing automatically compensates for misalignment between the shaft and the housing. The standard rolling-bearing steel 100Cr6 and the integrated sheet-steel cage ensure smooth running at operating temperatures ranging from -30 to +200 degrees. The open design allows direct access to the lubricant via the lubrication groove in the outer ring.

Under what operating conditions does the 22216 E/C3 self-aligning roller bearing prove its worth?

Design engineers primarily use this self-aligning roller bearing where high radial forces act on rotating shafts and where deflection or misalignment is to be expected. Typical applications include heavy-duty industrial applications where dynamic misalignments between the shaft and housing occur as a result of operation. Thanks to the lubrication groove and the lubrication holes in the outer ring, the rolling bearing can be relubricated directly in the bearing housing with grease or lubricating oil.

What benefits do increased bearing clearance C3 and running accuracy P5 offer?

The increased radial clearance C3 counteracts stress build-up should components heat up during operation or if there are tight fits against the inner ring. This ensures smooth running even when the shaft expands due to heat. Furthermore, the tolerance class with P5 running accuracy, combined with standard dimensional accuracy PN, contributes to smooth running. When fitting the open bearing, a clean housing seal is recommended to protect against the ingress of dirt.
