This is for a one new old stock Carquest RW-507-CR bearing.  The spacer ring is present.  The number on bearing is RW507C BCA.  These are Timken compatible.  The Timken number is the same.  This sale is for the bearings pictured.  Made in USA.

I have many other NOS bearings (all bearings listed are checked for free flow turning) and oil seals (500 plus). 

My goal is 5 star service to you.  Thank you for your business.
