Review: Bye again shop - Valued seller, quality goods
Review: nice bearing, low price - I'm using these as rollers in telescope focusers, and they seem to work well. Perhaps not as precision made as similar products costing ten times as much, but with six bearings per focuser and a saving of £2 per bearing, I'm fine with that. I haven't tried spinning them at 30,000 rpm, and don't intend to.

### ⭐⭐⭐⭐⭐ Bye again shop
*by T***S on 27 August 2025*

Valued seller, quality goods

### ⭐⭐⭐⭐⭐ nice bearing, low price
*by G***N on 11 January 2025*

I'm using these as rollers in telescope focusers, and they seem to work well.

### ⭐⭐⭐⭐ Not quite as precise as I was hoping for.
*by N***G on 8 January 2025*

I measured the ID at closer to 1/8th inch. (3.175) so they're a little slack on a 3mm shaft. They do seem to be smooth and effective though, but you might need to shim the shaft if you're after a precision fit.
