Anybody used these? Is there any real benefit over standard bearings? How do they hold up? | ||

I didn't even know such a thing existed. | ||

Racers use them for less rolling resistance but I don't know that I would trust them the distance standard bearings run. They may hold up ok, but I dunno. Pricey too. | ||

There were some threads on them a few years back. | ||

I don't see the point for our application. It is not that tough a use. Sure the ceramic balls won't suffer rust from water intrusion, but you still have metal races. FWIW, we use ceramic balls in turbocharger ball bearings. Keep in mind we are talking 150,000-250,000 RPM (but relatively small loads) and high temperatures. My really rough calculation says you would need to go somewhere around 9,400 MPH to spin your rear wheel bearing that fast! I did the math pretty quick for fun, so don't put that on your next math test... They also are plumbed into the vehicle oil system, so you have a constant flow of high pressure oil, not a captive (hopefully) amount of grease that must last the lifetime. | ||

We started using ceramic bearings in our seamer rolls on a can closer. This is what puts the lid on a beer can. The application was not that high speed but more high pressure, at least on the secondary roll. We would always be in there reshimming standard timkens to get our .001" end play but with the ceramics it was plug and play. They lasted a lot longer. Then again, this is a smooth operation without any shock load. I always wondered how they would hold up under a shock load, like hitting a pot hole. Ceramic is hard but also brittle. That's what would make me leery of using them on a wheel. | ||

Jim, what turbo work do you do? I have a couple Garretts that need love....one is a 60 trim VNT25, the other a 70 trim t3. Both from dodge 2.2 turbos... | ||

Put ceramic wheel bearings in my 08 uly they lasted about 500 miles. Finally broke down and bought the 3 bearing rear wheel from American Sport Bike. Nice wheel and piece of mind. Worth the money | ||

500 miles?! Installed wrong? Are they more sensitive to sudden shocks than steel? +900000 on the three bearing wheel. I went that route too. about 30,000 miles so far. My 2008 first set crapped out at about 15K. | ||

I would not use these and there is no need to either. The wheel bearings on this bike are a standard type with many higher grades if you want them. Just look at a web site to check them out. I would suggest the ones with metal seals myself. |
