Pulley for guiding steel cable
Used as a cable guide when I was rebuilding a rototiller. I also purchased 3/8 round steel that was a foot long and fabricated a shaft to hold the pulley. It worked really well. The pulley is strong and performed as hoped.

Solid
For those using inch units, this measured exactly 1.75" OD, with a 5/16" shaft, as per my calipers. Very solid.

Smooth and good quality.
Not much to say other than they are smooth and well made. They should be able to smoothly roll even with a decent amount of weight.
