415H O-ring Chain

G'day all

I'm only asking this question as i've done the research and haven't been able to find a manufacturer that makes an o-ring chain in 410 heavy duty and 415 heavy duty.

I know there is next to "no" chance of finding such a chain, but does anyone know if there's a manufacturer who makes specialist small size o-ring chains in specifically 410 and 415 heavy duty spec.

Hi Al

Thanks for the link but it's for 520 motorcycle o-ring chain.
I'm chasing 410H and 415H o-ring chain

I don't know of one...but it's a darned good question.

Ok, been doing more research and i've come up with a solution to the problem of finding a manufacturer that makes a 415H O-Ring chain for our motorised bicycles.
In Japan they sell a lot of specialised chains for small cc racing categories that we don't even know about, or even get to see the specifications on chain manufacturers english speaking websites.

I'm sure they would make a 410H O-Ring chain but as i can't read Japanese, the research side of things is almost impossible.

Other manufacturers would make a similar product but i haven't been able to find anything.

I'm not sure exactly why you want the o ring chain.
It's only advantage that i know of is it is pre-lubricated and won't allow contamination in.

Our chains wear due to the pressure at the pin joints.

I would look at REYNOLD chains.

SYNERGY is the top of the line.

Thats what i plan to use.

They may even have the o-ring chain.

But it will be under a product for wet applications.

That's exactly why i want an o-ring style chain.
Fine dirt, sand, road grit and other contaminants are what help to speed up the process of chain pin wear.
The biggest problem with non o-ring roller chains is keeping those contaminants out when the chain is lubricated.
You actually wash undesirable material "into" the chain pins, especially with solvent based chain lubricants.

If you've ridden your bike accross a sandy bike path-trail the rear tyre throws fine grit onto the Jackshaft area, even with mudguards fitted; some of it getting thrown onto the chain surface.

That's why i want an o-ring chain - preventing abrasive material from entering the pin area whilst lubricating the chain.

Keep us updated on what you find. I'd be interested in one.
