Great for automation projects
Using these in a linear actuator setup. Very quiet and low friction.

Reliable supplier
Second time ordering. Packaging protects the bearings well from shipping damage.

Good value bulk pack
Quality is consistent across the pack. One bearing felt slightly stiffer but loosened up after use.

Exact fit
Ordered the 12mm size for my 3D printer upgrade. Dimensions match the spec sheet exactly.
