How about the black oil from the meat grinder?
Shell is generally cast iron, no matter what material, a set of running machine, always want to close, since already spent money, use it.You can fold the meat that you don't want and put this black in earlyAnd when not in use, the hand turns (barring), feel there are some abnormal metal friction.
(the body is made of cast iron.) it may be cast iron. Use it
The oil seal is the part that isolates the bearings from the inside and outside of the machine.
It's not a bearing problem. It should be the oil seal.
