Typically, as has been discussed on here by several, welding a washer/nut on what is left will work.
However, since you are on a part that will be ruined with heat, maybe try one of the "easy out" tools. You may have to carefully drill a slightly larger hole depending on the easy out that you find.
The problem with the small sizes is that they break off easier. If it breaks off in there, you then have a bigger mess as they are difficult at best to drill out due to the hardness.
If you feel that you could use a wire welder and pop it enough to stick a washer/nut without transferring enough heat to cause a problem in the roller, that would be the way I would go.
Worst case is you locate another roller and problem solved. The newer ones have sealed bearings so no more button heads to grease or break off.

Just a word of caution. If you try welding watch you don't get a small fire started with all the grease.
I don't know that it would catch, and you probably wouldn't weld long enough to get one going, but just something to watch for.

Weld a nut to the end of it. You shouldn't have to weld on it long enough to ever cause a problem with the bearings. I'm with Ben though.....have a fire extinguisher handy. A small fire can turn into a big one in a hurry when your welding.

EZ out is easier.

An easy out should work well in this situation. This is a grease fitting so the threads should not be rusty. The top was broken off by impact and not twisted off like a bolt might be. A very small easy out may go too far into the hole in the grease fitting and bottom out against something inside. If you are worried about this happening, just use a bigger easy out that won’t go in as far. Likewise do not use a drill trying to enlarge the hole and drill too far through the center of the grease fitting. I have always had the fittings pop right out. Good luck. Gil

I've had good luck with the straight-type EZ-out and don't pound it in hard. It just needs to be in enough to bite and turn the broken piece out. If you pound it in, it will swell the piece and make it grip the threads even worse.

I don't know if this is what JD40c was referring to, but I really like the Lisle "super out". They sell a five piece set, #62900, which on eBay goes for as little as $15 including shipping. They are straight sided EZ outs which I think is an excellent design to distribute the torque and keep the screw from bulging at one spot. Over the years I have tried about every other style they make, from the Chinese junk to the fancy Craftsman designs, and these are far and away my favorites. Gil
