They should be able to smoothly roll even with a decent amount of weight. Review: 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. ## Features - [Material] Made of bearing steel material, not easy to wear, and lasting performance.
