Faga bearings have a reputation like a Mercedes from the 80s-90s, but if someone recommends them today, it's as if TODAY someone still believes in a Mercedes... so as not to leave a thick pipe, I'll ask: how many bearings do you replace per month, or on some other scale? My company performs 80% of the bearing replacement service, there are ~30-40 of them a day. Mainly group 62,63, some double-breasted, less often 60 and oblique.
And FAG has proven to us in the last 3 years that it is worth nothing. SKF has proven this long ago. Until then, we stuck to FŁT - now it's worse. I'm not complaining about Koyo and Timken, but they're not available in the performances we want. We stayed with Nachi. (Japanese)
Phages and SKFs were worth something 15-20 years ago, later we happened to get a whole skimming batch of SKF before setting up, and FAG crumbles to the stage of howling and wiping the casing after 3-6 months in the case of 20% of the assortment that is just junk . And I say this bearing in mind several years of observation of the working conditions of a given device, in which the phage bearing applied with the methods of real craftsmen described above (+ heat application, without ANY force on the bearing at all) is the only piece of the puzzle of meticulous repair of the device, where the crappy bearing costs PLN 30-60 and the losses in case of failure reach many thousands. PLN for the repair of the device, not to mention the possibly calculated costs of the downtime itself as a result of the failure. I would pay for bearings 5x as much as they cost on the Polish market if only they were better. Meanwhile, every few months, another wise man calls who has never put bearings in his life - a sales representative - and offers me that it will be cheaper.
NSK - double breasted are loud right out of the box (C3 2RS, no matter what basket) but in general I will neither recommend nor criticize.
Pessimistic, but welcome.
