Bearings and bushings are the small parts that let shafts spin smoothly. Boring job, quiet part — right up until they wear out, and then they get very loud very fast. A worn bearing means a shaft that wobbles, and a wobbling shaft eats everything around it: seals, housings, sometimes the shaft itself. Small part, big domino effect.
This is the genuine Nilfisk Advance OEM BALL BEARING, part number 1463633000, brand new in the box. Catching a bearing early — while it's just starting to growl — is the difference between a ten-dollar fix and a two-hundred-dollar one.
If you can hear it from across the shop, it's past due. Replace it, and while you're in there check the shaft and seals for damage from the wobble.
