[05:46:06] <goppo> hi
[05:46:19] <goppo> could teflon bushings withstand lateral pressure?
[05:46:43] <goppo> say 10N?
[08:43:09] <pokmo> hi
[08:43:26] <pokmo> could small linear bearings like this be used as a wheel?

[08:43:32] <pokmo> a 5MM rod can fit inside
[09:12:16] <SpeedEvil> They do not rotate well.
[09:12:24] <SpeedEvil> they are not designed for it
[09:12:36] <SpeedEvil> the balls only have freedom to move back and forward
[09:23:28] <pokmo> right
[10:16:22] <SpeedEvil> http://imgur.com/gallery/9I455Yk - how roombas are made.
[16:28:45] <pokmo> Are bronze or Teflon bushings meant to just slide o
[16:28:59] <pokmo> Fit over a rod, loosely?
[16:29:14] <pokmo> Or should the be press fitted
[16:51:54] <Tom_itx> bushings are not a press fit item
[16:52:29] <Snert_> in my really limited experience bushings are always a snug thng. Not really tight but no slop either.
[16:52:49] <DagoRed> pokmo: press fit. And what Snert_ said.
[16:52:59] <Snert_> yea kinda in the middle there.
[16:53:11] <pokmo> Could Teflon ones be press fitted too
[16:53:21] <pokmo> Won't they crack?
[16:53:30] <pokmo> From the pressure exerted
[16:54:08] <Snert_> press fit kinds of things are made to withstand the pressure it takes to press them in.
[16:55:00] <pokmo> What consequences would there be if they were loosely slides over?
[16:55:03] <Snert_> are you trying to roll your own pressfit thingerdoodles?
[16:55:36] <Snert_> it goes wobbly wobbly
[16:55:46] <Snert_> kinkup.
[16:55:55] <Snert_> falls over and the internet breaks.
[16:56:22] <pokmo> Basically I have a 5mm steel rod that needs to rub against the inner face of a 80mm steel pipe
[16:56:56] <pokmo> I wonder if I could do away without rollers ans use a Teflon bushing
[16:57:03] <pokmo> Loosely fitted over the rod
[16:57:41] <pokmo> And let the bushing act like a roller
[18:32:07] <goppo> anyone know if there's a bearing in nylon castors like this

[18:32:19] <goppo> is it just a plain bore like
http://www.componentforce.co.uk/userfiles/image/categories/replacementnyloncastorwheels_lg.jpg
[18:32:53] <goppo> but then, wouldn't the pressure exerted by the shaft crack the nylon though
[18:47:31] <Snert_> yea, it's cheap.
[18:48:24] <Snert_> http://www.allstrong.com/65-ball-bearing-casters.html
[19:40:05] <goppo> wouldn't the pressure be too focused and prevent the caster from rotating
[19:40:16] <goppo> Snert_, so all the weight is transferred to the nylon caster through the bolt shaft, right
[19:43:01] <Snert_> I'm just saying, ya want good stuff, it ain't cheap.
[19:43:15] <Snert_> ya need roller bearings? pay for them.
[20:01:22] <doomlord> http://www.kalrayinc.com interesting chip, i only just heard of this
[20:48:03] <pokmo> are nylon bushings more durable than teflon ones?
[21:33:42] <anniepoo> nylon is harder
[21:33:50] <anniepoo> but less wear resistant
[21:33:56] <anniepoo> what's the application?
[21:35:12] <DagoRed> I just know that urathane is the best in terms of performance.
[23:00:19] <pokmo> anniepoo: i'm thinking to slide a bushing over a rod so that it can rub against a curved surface
[23:01:01] <pokmo> if nylon was harder, it'd be easier to crack, right?
