بكرة حبل بفتحة جانبية

The profile hole aligned perfectly with my axle rod, so the pulley spins true without any wobble. It’s a solid little piece that took my mechanical project to the next level.

Snapped this onto my model crane build and the rope tracks through the groove without slipping at all. The profile hole lines up perfectly with the standard axles I already had, so no drilling or fiddling. Feels sturdier than the plastic pulleys I've used before.

The profile hole makes it so easy to mount on a standard axle without any wobble. I used it in a small lift mechanism and the rope tracks smoothly every time. Solid little part for the price.
