Crank with bushing M4

The bushing spins smoothly on the crank, making adjustments in my model much easier. It feels like a solid, precision-made part that holds up well during assembly.

I needed a replacement for a worn bushing on my model crane, and this M4 crank fit perfectly without any wobble. The machining on the bushing is precise, so the crank rotates smoothly.

This crank arm is noticeably sturdier than the standard plastic ones I've used before, the metal bushing gives it a precise, smooth rotation. It clicked right onto my existing model without any wobble. Exactly what I needed to get my project moving again.
