Any HQ sponsors carry these any longer?

No old stock left?

why do you want these specific bearings

[Tedder]

I prefer the roller cage that they used.

[registered user]

what cage is it? one piece steel cage works good im sure. polyamide is highly reliable and the type i use

[Tedder]

It's a solid one piece brass cage. At least I assume that's what material it is.

I'll run the polyamide ones without concern (my 10mil has one of that style in it) but if I found some old stock 305e's I'd grab them.

[registered user]

theres three common cage materials for roller bearings. brass, steel and polyamide. im pretty sure polyamide offers a bit less weight and friction than brass or steel. the only thing im unsure of is the long term ability to resist any deterioration from methanol. short term it seems to do fine

I used phenolic cage in bearing who were used in rc airplane running nitro methane for years.

Interesting bit of info in that link Claude.

Thanks

claude that material probly isn't common for this large of bearing so its probly expensive and needs special made. these charts show polyamide66 which appears to be a nylon and is common for bearings does great in methanol or any type of gas http://mossrubber.com/pdfs/Chem_Res.pdfhttp://www.professionalplastics.com/professionalplastics/ChemicalResistanceChartofPlastics.pdf

Cool info in here. Only a matter of time before some one just tells you to get your bearings from a sponsor and quit learning new shit.

The NTN 305E is the TZ style bearing we use and stock... Our picture on our website is just of an old photo from when we used OEM TZ

Thanks very much
