Need leads for HDPE rollers with bearings

[micmac]

I'm looking for someplace that sells HDPE rollers with a bearing through it, like this one:




Due to space limitations I'm unable to use idler sprockets. Also I need to be able to clamp the roller flush to a metal plate so just the old stock rollers wont work.

I've tried the usual suspects Mcmaster Carr, surplus supply etc.. but I've come up empty. if anyone has a lead it would be much appreciated.

Mike, i'm borrowing some machine shop time, and supplys next week to build the rollers for my hustler. i'm going to make a steel sleeve 3/4 OD, 1/2 ID by 2.125 long, to be able to bolt it tight, then a 2" OD roller with a 0.760 ID by 2" long. the roller is going to be made from self lubricating delrin so hopefully that will allow them to spin ok. i'm going this route because i've struck out on all searches for a bearing roller with a big enough bore size. if these sound like they might work for you let me know and I can make a few extras and send them up to you.

I've been looking for something to use on the rear chain adjusters myself. The Bigfoot doesn't have enough space to use idlers either, and a pinch-type floating adjuster will push the upper chain into the frame members. If you are going to produce more than you need, R13, I'd be glad to buy a couple as well.

it will depend how much material i can get my hands on. i may have to start paying for material if i do too many. another option is once i get mine done, i can get a price on having them made. the Delrin is $56 a foot, so i don't want to push my luck too much

I've used these guys before, fair prices, excellent quality.

When I saw the pictures the first thing I thought of was a wheel off a skateboard/rollerskate. I'm not sure you would be able to bolt flush w/o a little modification or if they would last... just food for thought.

Great idea, Adam. Cheap and effective......I think that might actually work with some slight modifications.

new here but a chance to spend my two cents worth you may look at atv/mc chain rollers a couple places come to mind at rockymountainatvmc.com and possibly denniskirk.com tim

[spud9slim18]

got to looking through some of my son's old atv racing stuff and found a used chain roller two roller bearings #608-rsz w/one steel seal and one rubber seal each i dont think these are metric bearings the i.d. appears to be 5/16 .313 is what i measure o.d. 7/8 .870 measured width little over a 1/4 .275 measured hope this helps tim

I see some potential with some of the rollers that rockymountain sells. I'll contact them to see what the specs are.

when the shop foreman saw the stick of material i was grabbing, i got run out of the machine shop i handed my drawings off to my friend Shawn who had let me in in the first place, and he is going to make my rollers on monday. he is also going to get me a price per unit, and if it isn't a totally unreasonable number, i'll post here.

[spud9slim18]

i looked in mc master carr. the 608 bearing is metric. id 8mm x od 22mm x w 7mm . sorry for any confusion . afterthought you could turn a roller to accept larger bearings of choice. just dont forget the pinch spacer. tim

I like the idea of the rollers for a few different ATV applications. Egoperf and Mark M. have been working on updated Max II chain adjusters, and one of the issues they were running into (if I can describe it well, and accurately) was when the roller was only supported from one side (i.e., a bolt through the roller, bolted to a piece of Unitstrut) it was difficult to get pinch spacing right so that the bolt would tighten into the Unitstrut firmly enough to stay tight, but not so tight that it would bend the spacers. I guess the bushing in the roller actually collapsed the washers (for lack of a better term) on each side, and tightened up on the roller. The roller didn't roll anymore, and it actually acted as a slider. Since there's such limited contact area on that circle, the chain ended up chewing right into the roller, and it never really rolled again, from what I understand. I think this could be eliminated if you could support the roller on both sides. I don't know if this is practical on the Hustler; I just don't have familiarity with them. I'll have to go look through the pictures.

Mike. I corrected that problem by making the roller a slight bit narrower and making new 1/4" thick washers that go up against the unistrut. However, after all that messing around with rollers we went back to the gliders but with the unistrut mount not that pesky ratchet style adjuster. So far it has proven reliable. I am not sure that the Hustler could use the gliders or not.....maybe.

any spacers (tubes washers ect) are the size of or a hair smaller the od of the inner race of the bearing that way when bolted up tight there is no lateral load on the ball bearings themselves or the outer race and it should spin freely no problem / tim
