Todd is doing skipball on those 5205’s? I asked a friend of mine who’s an engineer about it and he was wondering what the axial and radial loads of the crank were on the bearing. Considering they use these engines for paramutual racing in Japan an engine failure would mean they would have to...

Correction the 52xx series bearIng is a 5205. What applications have you done skip bearings on? Give me a sense of what could be done.

The 6202’s are for the gearfoot. The 5202 is for the crank on the bottom. Not sure it’s a good idea to run skip ball on the crank because if I throw the crank I‘d probably lose the pistons, rods, case, etc. It would be costly. Crank spins the driveshaft directly with no support on the shaft...

Do retainer and shield materials influence performance and longevity much? Retainer vs no retainer? We have bearing suppliers in our area. Last ceramics I purchased came from Performance Bearing out of Utah. I need 6202 3pcs and one 5202. The rest are need bearings which I haven’t seen ceramic...

Yes I know who Todd is, done some business in the past. If I’m not mistaken don’t you get more revolutions out of a bearing with a tighter tolerance than one with a looser tolerance using the same amount of energy on both? How does oil viscosity affect bearings? Do they make ceramic needle bearings?

No not overthinking it. Back in the early 2000’s before ceramics SKF 6202 ABEC 7’s were 500 CDN a pop. I found something comparable but I’m positive they were Chinese in origin but they were still 100 each. Last ones I purchased were from a company out of Arizona claiming they manufacture...

Hi, I’m new here to this site, following karting from time to time. I’m involved with stock/mod outboard racing. Specifically want a recommended precision bearing manufacturer. Looking for high (ABEC 7 or higher rated bearing) rated ABEC ball bearings and good quality. Another question? Are the...
