86 250R Dual Row Bearing Carriers

[MyMistress86R]

Who's running these? Are they worth it? Any and all input is appreciated.

this may seam kinda dumb but what exactly is the difference with these? do they use 4 bearings? ive never played with bearing cariers before as all my trikes have been shaft drive or hard tails. I was wondering about if it was worth getting one of these for my 200x project.

I have a couple of them and I think they are a waste, your paying double for bearings but does the inner bearing even ride on the axle? It looks like it may make contact but the axle starts to taper off. I'll have to get some measurments on this from one of my extra axles. I'm running a stock carrier on an extended axle. The aftermarket carriers look good and there is more adjustment so you may get a little more chain life or adjustment with those.
I think the stockers last if you take care of them, I could see using the double row if you run a heavy rear tire.

I believe they use tapered roller bearings which can handle sideloads that a radial bearing cannot. The inner race should most certainly contact the axle completely.

I have a dual row carrier.The bearings are wider than stock bearings.The stock ones have one row of bearings.The bearings in mine have two rows of balls in each bearing.

they are only realy needed if you have a problem eating stock bearings

im running a double row now but i have converted my 110 to taper bearings and have used them in the past....nothing rolls smother then taper bearings

I have double row bearings in my woods bike. The 250R is notorious for going through rear axel bearings. I've bought the double row carrier about 10 years ago and have never replaced the bearings again. They are still running strong. I ride in one of the rockiest parts of the world (Tower City PA) and can say that they work well.

You can also get a tapered bearing for the 86 carrier. I have the tapered carrier in my 86R. That doesn't get much woods riding, so it's not fair to compare, but that has about 10 years on it too.

Dual row, I misunderstood you. Thats not a tapered bearing setup which I believe to be the best upgrade.

But dual row or twice the bearings is certainly a good upgrade. What leads you to believe the inner bearing doesn't touch the axle surface?? I'll bet the Honda OEM axle is only ground to the correct outside diameter to run against the 2 stock Honda bearings in the stock carrier and axle outer surface tapers in after that. Thats what you meant by tapered after the outer bearing - correct?

In that case, the extra inner beaing is useless unless it's run with the aftermarket axle that is ground to properly seat against both the inner and outer bearings inside races.

So unless the proper axle is ran, the extra inner bearing is useless and adds no additional support to the carrer/axle. I actually adds weight.

Does that answer you question?

[SWIGIN]

there is no inner bearing its just a wider double row bearing

i have had them all. the dual row is a excilent choice. and the tapered bearing is the best. the dual row is much better than stock.

I have dual row carriers, I thought of tapered carriers, but there is limited chain adjusting, the bearing is open(not sealed and requires frequent cleaning) and how tight the axle lock nut(s) are have alot to do with how long it lasts. If the bearing is loose, the axle will wobble alot, if its too tight it will have short life span and not roll good. You need to have it somewhere in between this, the dual row carrier seamed like a better choice. The tapered carrier takes side loads alot better, but its draw backs make it a bad choice for woods or mx riding. They are a great choice for tt and flat track use.
