Are the es and sx front brake drums/hubs the same?

[jasonb01]

My front bearings are going bad on my 87 es and i have a brand new front brake drum/hub for a 85 sx in the shed. It is the complete front end with the drum and the tube that holds the bearings that the axle slides in. Sorry, I am not good with part names. That is the hub, right? Anyway, are these 2 bikes the same size, or will I need to order bearings for the es? Thanks!!

I looked on bike bandit and the hubs and brake drum numbers are off by one. I guess it won't work. I'll stop and pick up some bearings today and just replace them.

Just done the front bearings on my Br. Don't forget to put the spacer tube in before fitting the second bearing!
