The dimensions are small and the quality assurance is not enough. Do not use them for an accurate 8mm system.

The bearings are small and cannot be used with a true 8mm system. Both bearings had an inner diameter of 7.94–7.96mm, while the true 8mm bearing measures 8.00–8.02mm. One bearing even has manufacturing defects such that the ID at one point is 7.90 making fitting an 8mm rod impossible.

Pros

Smooth, quiet, low friction and low maintenance, very suitable for 3D printer Z axis.
