I am sure I have seen a reference to this somewhere on the forum but cant find this nowt

I believe the KOYO 32005JR (upper) 32006JR (lower) come with a built in rubber seal, but not totally sure.
All the bearing reference numbers that I have for the headraces are below:
Upper: I/D 25mm x O/D 47mm x W 15mm (SKF 32005XQ) (Koyo 32005X or JR) (Timken 52005X) (FAG 52005X)
Lower: I/D 30mm x O/D 55mm x W 17mm (SKF 32006XQ) (Koyo 32006X or JR) (Timken 52006X) (FAG 52006X)
