Hello dear friends
I know it clearly that FAG bearing company has produced this type of bearing ( nnu 41/560) with lubrication groove in INNER ring,but what i don't know exactly, is what is the complete suffix of this type that has lubrication groove in inner ring.
 The second question :Is SKF bearing company has this type of bearing too,or not?
and if this type is valid in SKf's products,what's the exact suffix of that.

My catalogs do not list inner ring lubrication grooves and I could also not find it on the Medias website.!*NNU41%2f530-M;bskvXfk6wZOf

They do not go up to the 560mm bore in the catalog listings, so I would think what you have is a custom bearing that would not be listed.  Your best option is to give applications engineering a call to get the correct part number.  Since FAG was bought out by INA Bearings and is now calling themselves Schaeffler, many of the suffixes have changed, so it would be a good idea to call and confirm the numbers anyways.
