Linkbelt eats pully

A few weeks ago someone posted a message asking if linkbelts eat-up pulleys. Well here are two pictures to confirm that they do. This one is off my Delta lathe. No question about it when looking at the linkbelt - it's coated in metal dust.

This pulley is 41 year old. I put the belt on last year. I've taken linkbelts off of all my machines.

The pulley I got at Sears all those years ago. The linkbelt was from Harbor Freight.

That was what I meant judging from the color.

What we do not know, is how much wear the previous 40 yrs created.

The pulleys (I have the lathe counter shafted) get a workout on my Delta as I use it for wood, metal turning and all my buffing needs. From the looks (mixed with my intuition), the belt eats the metal. I recently looked at a Delta scroll saw made in 1935 fitted with an equally old (or older) GE 1/4 hp motor and original pullleys. Those babies were almost 80 years old and still running.

I can't say for certain that it wasn't pulley failure, but it's the first time in 42 years I have ever had one and all since I put that link belt on a year ago.

I guess I could google it, but what is the benefit of the "linkbelts" over a standard belt?

I converted my 1963 Craftsman table saw to a link belt recently. However I changed the pulleys from the original crappy ones to machined steel pulleys. I don't think the original cast aluminum ones would hold up very long with a link belt.
One thing to make sure about. Link belts are directional. Make sure they are installed correctly.

Link belts reduce vibration, so are generally quiter.

The greatest advantage is they are adjustable length. Belt too long, remove a link. Too short, add a link. Need to install on a captive pulley, open the belt and install, then close it back.

The entire belt is made up of identical links.

I was the one asking this question recently. I actually read it in the 10ER forum in Yahoo.
