Great Spacer

Perfect for motor mounting applications. The threadless design makes it easy to slide into place without cross-threading.

Good Value

Nickel plating looks nice and provides some corrosion resistance. Would buy again for future projects.

Excellent Fit

Used these for a 3D printer upgrade. The inner diameter was spot on for my shafts and the nickel plating looks professional.

Solid Build

Good steel quality and feels durable. One sleeve was slightly tighter than the others but still usable.
