Trying to locate a 32009 tapered roller bearing.

Just plain 32009.

All I find are that number with X, XA, etc. suffixes.

OK to use or is there something vastly different?

And who is your favorite bearing supplier?

One of the common ones is an SKF32009X/Q where X means the boundry dimensions were changed to conform to ISO.
And Q means optimized contact geometry and surface finish.


Question is what do these go in?Milling spindle will matter more than a wheel bearing.Oem's don't always give us all the suffixes we need.

I prefer SKF myself for bearings. The suffixes (at least here in Oz) seem to vary by manufacturer, so you might have to pick one and ask them to explain. Typically, suffixes are used to indicate variations on a basic design and can indicate the presence or not of seals (and the type), type of grease, cage material, variations on bearing shape (flanges, diameters, mounting holes etc)
