Maybe 5/8" is a little big for your application,but 5/16"is a big drop in size and strength 1/2" may be the way to go but if your set on going smaller shaft size and still wont strength try hardened shaft cold roll steel or stainless shafting attaching sprockets to unkeyed shaft mill a flat spot on the side of your shaft for a set screw to set in then double up on your set screws so that your set screw will stay in place or use a locking coller drill through both the locking coller and sprocket hub and bolt them together my two bits cheers : )

I definitely drive a little harder than most probably would.
Still, the potential is there that a smaller diameter axle my bend under
even less harsh circumstances. Especially if you need to run a decent
amount of tension on your track ( ie. Friction drive) the heavier the
axle the safer you will be.

What were the conditions that caused it to bend?
I assume it was more than normal use . . .
