Some 40mm too. 

I use bearings for hose connections. So we press a steel pipe into i.d. of bearing. I would like to find bearings where the inner race is tall. This will eliminate us pressing pipe.

If it's a 40mm bearing inner race should stick above top of bearing 40mm. If it's a 60mm bearing inner race should stick above top of bearing 60mm and so on.                

We can slide our hose onto inner race instead of pressing pipe into i.d.                            

Just make 3mm wall thickness    

Can you offer the bearings?
