Hi,
I am curious about lubrication of bearings on a Probat. I have a link to a video showing the one I mean but I can't post links here. If you search "coffee roaster bearing grease" on YouTube it's the one from Wolff College of Coffee.
My question is: What temperature should a lubricant be able to withstand if it is going to be effective on those bearings and not run out or break down? What do you guys recommend?
Thanks
