I needed a bushing for an old change gear setup, and the 9 mm ID and 20.3 mm length matched perfectly with the keyway slot already cut. It slid right onto the shaft with a snug fit.

The slot for the 4 mm key lined up exactly with my gear’s keyway, so installation took under a minute. At 20.3 mm long, it sits flush and hasn’t shifted during a few test runs.

The 16 mm OD and 9 mm ID fit perfectly on my lathe, and that 4 mm key slot makes assembly a breeze. It's exactly the dimensions listed and feels solid during use.
