drive shaft lower speedometer bearing

[yamahaty]

Hey guys I have a question....i just pulled out my bearing behind the speedo and went to a local nsk dealer....the bearing i pulled out was a ub205 and they gave me a 205...what's the difference? and can i use this bearing???

Is there a collar on the bearing for the set screws like on the old bearing. If there is should be good to go

 

[yamahaty]

yes but i'm just wondering about the UB....i can't seem to find out what that means....

I do believe the UB (prefix) is the type of seal they use.

 

[yamahaty]

think it's alright to use???

Sometimes the maker of the bearing will add their own letters before the number, do a side by side comparison to check. But if the local nsk dealer gave you the bearing by what you gave them, should be it.

Timkin makes a replacment also. I went to a local bearing supplier with my old one. They gave me basicly the same thing except it has a concentric locking collar, instead of the 2 set screw collar like stock. IMO the concentric locking collar lets you lock down on the shaft much more than just 2 set screws.
