Main Bearings

Posting a quick quiz! I am going to putting my cases together shortly, they have been sent to be vapour blasted and other bits have come back looking superb. The question is with bearings. I have taken out a pair of FAG main bearings NU306E, I had what I thought were FAG bearings in the garage, but when I went to get them they have some how changed into RHP HJ306ETN, are they the same? I have had them for a few years (15+!!) but they are still in sealed packets. Cheers,

'HJ' bearings appear to be NJ type with an additional 'angle ring' to support the rollers? Presumably the angle rings are separate parts, and would have to be removed because I doubt the bearings would fit otherwise?
