Single nose wheel bearing

I have searched for a part number and does not come up on the internet or I get instructed to call Vernon Gregory (he is an invaluable source of information and parts and I give him much of my requests) but a Timken bearing number that works is 6207-2RS which is a rubber seal both sides deep ball bearing.  It can usually be picked up locally or ordered off of Amazon and is not expensive.

I replace mine when I can start seeing oil leakage which is about every 2 years.
