Our catalog record for this one is thin - it only shows up once, tied to a rear wheel figure with a 1971 date. We don't have enough here to tell you which specific model it belongs to, so if you're ordering against this number, best to confirm fitment against your own hub and swinging arm before you commit.
If you're replacing one, it's worth checking the spindle for straightness and wear where the bearings ride, since a bent or grooved spindle will chew up a new bearing in short order.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
