So the bearings on both idler pulleys are shot on my ST824.  Unfortunately, the pulley is tack welded together; to replace the bearing you must replace the pulley as well.  At $20 each, I'm looking for alternatives.  Anyone consider replacing this,

with this?

My concern is the shaft diameter appears to be about 3/8" on the MTD part and 1/2" on the Ariens.  So, that's a show-stopper.  But there must be an alternative.  Perhaps I could drill out the weld and rivet it back together with new bearing installed.

As far as I can tell, this would be the replacement bearing...not 100%.

Although, I do see Sten has replacements that are less expensive.

Check out flat idlers and flat idlers without flanges.  They have detailed measurements so you should be able to get something close to yours.

Of course, if you can press out the old bearings and press in new ones that works too.  Maybe use a socket with a vise or a c-clamp.

When you buy your new parts, pop of the dust shield with a very dull razor blade (sanded dull)   and pack  more grease into it and you will never have to buy the part again.
