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.
Q: What is the standard length of these sleeves?
A: The standard length is 10mm unless otherwise specified in the variant selection.
Q: Is the inner surface smooth for rotating shafts?
A: Yes, the ID is reamed for a smooth finish suitable for sliding or rotating applications.
Q: Is it suitable for high vibration environments?
A: Yes, the tight tolerance ensures a secure fit that withstands moderate vibration.
Q: Does the nickel plating prevent rust?
A: Nickel plating provides good corrosion resistance, but we recommend avoiding prolonged exposure to moisture.
Q: Can I order a mix of different IDs in one pack?
A: Please select specific variants for each ID. Packs contain uniform sizes per SKU.
