Perfect for my 3D printer
Fits perfectly on the X-axis carriage. Smooth rotation and no play. Exactly what I needed for the upgrade.

Exact dimensions
Measured with calipers, spot on 8x16x5 mm. The flange diameter is also accurate. Reliable supplier.

Good value
One was slightly stiff out of the box but loosened up after a few minutes of use. The rest were perfect.

Great quality
Used these for an RC car upgrade. No play in the bearing and they spin freely. Good value for the price.
Q: Is the pre-applied grease high temperature rated?
A: It uses standard bearing grease rated for temperatures up to 120°C. For higher temps, special lubrication may be needed.
Q: Can I buy just one piece instead of a pack?
A: No, these are sold in packs of 10 pieces minimum to ensure safe packaging and handling.
Q: Is this compatible with NEMA 17 motor mounts?
A: Typically yes, these are commonly used for pulley mounts on NEMA 17 setups. Please verify your specific shaft diameter.
Q: Do you ship internationally to Canada?
A: Yes, we ship worldwide including Canada. Shipping costs are calculated at checkout.
Q: Is the flange on one side or both sides?
A: The flange is located on one side only, as per standard F688RS specifications.
