Alemite shows standard and giant sizes, not sure what variants there may be on the older track rollers and or similar applications that Allis may have had.
I'm going under the assumption that if Allis track rollers were similar and called for the same lubrication as the old style caterpillar rollers, then it should be what was called track roller grease/lube. I'm not sure if its in production, I recall Chevron Marfak, (see attached link) is an NLGI 00, 0, 1 grease. The Marfak NLGI 00 is recommended for crawler track rollers, see the attached cut sheets, where it states this. One I am aware of that should be the correct lube, though there are many out there, I am unaware of what the original specifications were by manufacturer, and the products called for then, something like this should suffice with the characteristics stated in the description.
