registered user Posted December 18, 2016 Report Share Posted December 18, 2016 why do you want these specific bearings Quote Link to comment Share on other sites More sharing options...
Tedder Posted December 19, 2016 Author Report Share Posted December 19, 2016 I prefer the roller cage that they used. Quote Link to comment Share on other sites More sharing options...
registered user Posted December 19, 2016 Report Share Posted December 19, 2016 what cage is it? one piece steel cage works good im sure. polyamide is highly reliable and the type i use Quote Link to comment Share on other sites More sharing options...
Tedder Posted December 19, 2016 Author Report Share Posted December 19, 2016 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 Posted December 20, 2016 Report Share Posted December 20, 2016 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 Quote Link to comment Share on other sites More sharing options...
ClaudeMachining Posted December 20, 2016 Report Share Posted December 20, 2016 I used phenolic cage in bearing who were used in rc airplane running nitro methane for years. Envoyé de mon GT-P5113 en utilisant Tapatalk Quote Link to comment Share on other sites More sharing options...

Tedder Posted December 20, 2016 Author Report Share Posted December 20, 2016 Interesting bit of info in that link Claude. Thanks 1 Quote Link to comment Share on other sites More sharing options...
registered user Posted December 22, 2016 Report Share Posted December 22, 2016 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 1 Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted December 22, 2016 Report Share Posted December 22, 2016 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. Quote Link to comment Share on other sites More sharing options...
