Review on FAG 51103 Grooved Rotational Capacity by Jayshawn Cuatlayol

My CNC router came with cheap thrust ball bearings. After replacing them with the same original brand bearings which failed after only 6 months, I settled on standard bearings. I can't comment on durability as I've been on vacation since installing it. I can say that the bearing is superior in quality and design. I expect this bearing to outperform the factory bearing it replaced. The bottom line is that when you buy a cheap car you will quickly see where you are saving. Bearings are cheap so I'm not complaining. I got about 1500 machine cycles from a cheap original bearing. I'll be counting cycles with this new stock.
