SKF YEL206-2DW/AG Spannlager (30x62x48,4)

As an insert (Y) bearing, this bearing is located on the shaft and used in a housing. This SKF bearing measures 30x62x48.4 mm and weighs 0.36 kg; the specification table carries the supplementary technical details. The insert bearing is made for mounting on a plain, unstepped shaft: it is locked in place rather than clamped between a shoulder and a nut.

An insert bearing combines two things: a wide inner ring locked onto a plain shaft, and a spherical outer ring that can swivel in its housing. The position therefore absorbs the alignment error that is unavoidable when mounting to sheet metal, castings or welded frames — the type exists for applications where the surrounding structure offers no raceway quality.

Depending on the version the inner ring is secured by grub screws, an eccentric locking collar or an adapter sleeve; what matters is that the shaft is clean and to size in the seating area, because the ring draws its entire grip from that joint. The swivel is for alignment on assembly, not for running: a misalignment that rotates continuously works the seal and shortens life.

The contact seal bears against its counterface and closes the rolling chamber against dust, splash water and wash-out; in return it raises frictional torque and limits permissible speed. Rings and rolling elements are made of through-hardened standard bearing steel.
