I'm designing a fatigue testing machine used to test bicycle wheels. A core component is a drum which needs to be about 1000 mm in diameter, about 200 mm wide, spin at about 250 RPM, and take about 800 N of radial impact loads. I've received quotes for fully custom drums of around $10k, but I'm hoping to figure this out for less than $5k.
I've been trying to find flat belt drive pulleys of about this size but they aren't easy to get new and hard to find used. Can anyone recommend a source for something like this?
