Good but packaging

Bearings are great quality and fit perfectly. The packaging was slightly damaged during shipping but the product was safe.

Great for printers

Silent operation on my 3D printer fans. Highly recommend for anyone looking to reduce noise.

Needed different seal

My fault for not reading the description carefully. I needed rubber seals instead of metal shields, but the quality is good.

Exact dimensions

Measured with calipers and the inner and outer diameters are spot on. Precision is exactly as advertised.

Smooth operation

Used these for an RC car upgrade and the difference is night and day. Very smooth rotation and no play.
