We use aluminum pulley stock from SDP-SI. We ordered 2 long lengths of it and cut it to the exact length we needed, and then finished off the ends on a lathe. Picture.

We then put the sprockets in 3x1.5" tube. Extra picture.The sprockets are 5mm pitch, 25 tooth. Anything larger than that size is certainly overkill. (I think OD is around 2".)

I'm just wondering because I feel like a flanged sprocket is a safer bet.
Reference photo above. Had no issues all year.
