Hello grinding masters,

I am new for bearing field and start a project with bearings application.
Two questions confused me about the bearing race super finishing.

>>  Why outer race of four points contact ball bearing can not be super finished ?
    This geometry is like two gothic arch formed, like below
 http://www.fag.com/content/en/products/productinformation/rotativ_products/four_point_contact_bearings/four_point_contact_bearings.jsp

       Dose someone can do this or any machine info ?

>>   How to super finished spherical roller bearing?
       Any vendor or machine information is helpful?

Thanks and regards,

FreddyMusic

Where does it say that "outer race of four points contact ball bearing can not be super finished?"

My 2 cents worth:
A less-than-super finish is better at holding lubricant.
With the four point contact bearing race, this is even more important due to limited contact surface area. The ball is probably highly polished, so the race must maintain the lubricant better.
