Decent quality
Run smooth enough, bolt pattern as it should be. Would support more weight that they need to I’m sure.

Good bearings.
So far with the multiple purchases of these bearings they are holding up to what need them to do on my miter saw slide rail work bench. Smooth rolling action all across. No laps or waddling during movement. I'm satisfied.
