Confused about these different arbors

I just picked up a used Model 520 unit this last weekend. I just pulled all of the arbors off of the saw blades that were included with the unit. Here is a picture of these arbors. Two of them I know what they are but the other two I am unsure off. Are the 510/520 arbors longer than the standard Mark V - 500 arbors??? Are the two with question marks different variations of the 510/520 arbor? If somebody can take a look at the picture and enlighten me that would be great.

Thanks,

I think the following link will answer your questions. It is pretty difficult for me to determine the difference just from a photograph. So, check it out and see if it helps:

Thanks ANMIUS! That did help. I think I am going to get a labeler and label all of my arbors so I can easily tell which ones they are.

Once you have them side by side they are easy to tell apart. The ones that have the nut on the headstock side are for 1 1/4 blade arbors and the others are for 5/8" sawblades. I prefer the ones with the larger diameters. I believe that the extra weight will dampen some vibration IMHO.

Yes the 505-510-520 saw arbors are longer than Mark 5 and Mark V 500.

I am guessing the second from right is also a 5/8" arbor, but cannot tell from the back side.

Maybe we need a thread that is a pictoral guide to all official attachments, starting with arbors and going up to bigger items.
