Since ball bearings are easier to lubricate than roller bearings, the low temperature performance limit is less important for ball bearings."

This suggests to me that most NLGI 2 automotive greases would be fine. I found an additional link that explains some of the ASTM Tests: http://www.usaindustrialgroup.com/oilanalysis.htm

From this, it appears that Pour Point is a useful characteristic: "Determination of the lowest temperature at which a petroleum product may be used if fluidity is necessary to the application."

I personally have been using Valvoline greases for my bearings (because I use it on my cars). I've used the Durablend ($3 for a 1lb tub):

The Pour Point is listed as -18C under the Product Specs link.

It appears that the full synthetic works to an even lower temp:

The Pout Point is listed as -80F (which is -62C), although the viscosity index is higher 135 vs 110.

Based on all of this I think I'll stick with Valvoline Durablend at $3/tub. Does anyone else have any other conclusions on a good grease at a good price?
