Hi all, looking for new bearings and I am hoping some here have more experience with bearing part numbers that I do.
For example I am looking for a bearing to replace 6007Z and I think the "6007" part is the spec or defines the diameter. I see higher quality bearings ABEC7 or 9 often have additional letters like after 6007TCG12P4 or even before like S6007CTAA7. I am assuming the letters deal with type of seal single or double or grease or heat range or bearing material or seal material etc. Is that correct in that physically the diameter of 6007TCG12P4 or S6007CTAA7 is the same as 6007Z? The other letters are outside the general fitment spec, I can check size 35x62x14 for example but assuming the size is the same they are interchangeable when going from a low tolerance ABEC1 bearing and going up in quality. I assume going down in quality those letters mean more.
Can anyone confirm his?
Thanks.
