tThanks that would make sense since I thought the kegco mills were from the same makers as the cereal killer only without the base but...
The first page of this thread as well as the following description from kegco says they use oil impregnated bronze bushings for some reason.. I skipped a few pages of the thread so I apologize if its been discussed and I missed it..
kegco even goes into detail claiming "SAE 841 oil impregnated bronze bushings " under the features here

"The Kegco KM11GM-3R Grain Mill is perfect for large batches and high efficiency milling. With three rollers, all your grain will be crushed twice in one cycle. The initial crush is through the fixed gap between the top two rollers, and then the grain passes through the second gap between the drive roller and the adjustable bottom third roller. The initial pass slightly flattens the grain, getting it ready for the next crush that breaks apart the grains and loosens the starch with minimal husk damage
The aluminum hopper can hold up to 11 lbs of grains and the roller body features an alloy block frame that houses three steel rollers on oil-impregnated bronze bushings. The drive shaft and all axles are integral to the roller, which makes clockwise or counter-clockwise drive possible. A hand crank is included, but the mill can be easily motorized with a corded electric drill. You don't need any additional attachments, just stick the drill on and go. Stainless knurled knobs allow a gap spacing adjustment range of .070". Adjusting is simple - just loosen the adjustment screws, adjust the gap and tighten the adjustment screws. You will need to supply or build a base to set the mill over a grain bin or 5 gallon bucket. "
its kind of a big difference to get wrong...
