roller chain mtrl
(OP)
I am faced with a problem of making a custom roller chain. It is a 160 pitch chain, and the issue i have is with the roller material. Does anyone know what material is used in standard roller chain rollers?. It has a high Rc value, but must not shatter, and is hopefully readily available.
Thanks
Thanks

Current problems that exist are the rollers shattering. Expected chain life is 1 year at 80% run.
pins show a Rc of 40, And the roller Rc 50

For a quick one off I have made some rollers from D2 Tool steel and Nitrided 17/4. The only problem is that you have to watch your lubrication using the standard pins and bushings.

Where are you located at?

The 2" pitch is no problem.
The 1.125" dia. roller is no problem.
The 1/2" side link could be achieved by stacking plates.
The problem is the roller length without using a double roller or a multi strand arrangement.
Here are some leads on "Sharp Chain" you might want to checkout. The USNR site looks like they make the bigger stuff, the question is whether they can drop down to 2" pitch.
