Exploring the wonders of angular contact ball bearings for the past few days.
I noticed that not all bearings that SKF produces are listed in their online catalog.
Here is an example:
https://www.bearingboys.co.uk/SKF--F...earing-22418-p
Not listed in the online SKF catalog:
Angular contact ball bearings, single row
Another one not listed:
https://www.grainger.com/product/pro...Bearing-36K560
Why are these two bearings nowhere to be found in the SKF catalog or on their website?
