Good but tight fit

Quality is good, but the fit was slightly tight on my shaft. Needed slight sanding to glide perfectly.

Great for CNC Z-axis

Works smoothly on my router setup. The plastic material keeps noise down significantly compared to metal bearings.

Solid plastic build

Good for light duty applications. I would not recommend for heavy industrial loads, but perfect for hobbyists.

Exact replacement

Fit my old printer frame perfectly. The flange holes lined up without any modification needed.
