Bearing size - LA165 - 48" Deck

I have the LA165 with the 48" deck, 300 hours and I know the far left spindle bearing is just starting to go out. Its just starting to make a whining noise the last couple weeks, interestingly enough it started to happen just after I serviced the deck and greased the spindles. Does anybody know the proper bearing sizes? I am going to run these until the end of the season and press new bearings in when I winterize the deck. Quick google search tells me I need 3 GX20818 and 3 GX21510, those are the John Deere part numbers but nowhere can I find a listed size.

6203-2rs for both bearings according to my aftermarket mower parts distributor.

Use 6203-ZZ with inner shields removed as regular 6203-2RS can't be greased without the inner seals colapsing into the bearings under grease pressure. But IL even the image from JD parts shows 6203 bearing for both part numbers.

Didn't look at the JD parts site since I already had the part numbers from then OP. Kind of funny that JD list 2 part numbers for the bearings in the same spindle, and happen to be the same bearing unless there is a seal change between them.

Looks to be the same bearing to me...Now maybe the GX20818 has the shields on both sides.

Thanks. Ordering those bearings tomorrow so I have them on the shelf. The difference between the two JD part numbers is that one is fully sealed and the other is only sealed on one side. Its the lower spindle bearing that is not fully sealed. You can see it illustrated on this site. https://www.rockymountainbearings.com/products/john-deere-gx20818-gx21510-blade-spindle-bearing-set

Ill probably just buy the fully sealed bearings and on the lower bearing I will remove the seal on one side so they are still greaseable.

Just did that to two spindles today.

Just don't forget to give them a stroke of grease a couple of times a season.
And don't wash the deck with water .
