Just as the description promised. Maybe in the future this vendor could have pulleys in the metric bore but imperial measurements on the diameter. I really needed a pulley with a 12mm bore but a 3 inch diameter. It’s close enough but, it makes factoring calculations for rpms a little stressful.

Needed a light weight pulley for spinning an old Singer machine with a small motor shaft diameter . 8mm 😱 which meant I had to drill out the ID of the pulley - easy to do wit it being aluminum ðŸ‘👠we are working on nowðŸ‘ðŸ‘

I have been searching for a pulley that was the correct size for me, and this item is made exceptionally well. The size is perfect, and the set screws hold it in place well. I used it to mount to a drive shaft for a grain mill, using an old drill press motor. The resulting ratio is exactly what I needed.

Bore was only 13mm not 17mm overall diameter was only 45mm not 80mm. Did not need this item until after the return period ended. Belt size also for a tiny skinny belt not a 1/2" belt.

Works well for running a mini lathe with a treadmill motor and 1/4" belt. No vibration at all.
