I have an old AC harrow that uses the bearing 70330133. My local bearing supplier can't cross reference the bearing. Does anyone know a source for the bearing. It has a 1 inch ID with an outer diameter of 3 inches and a width of roughly 2.5 inches.

I would prefer to keep it original, but I saw a post where someone put three bearings together in the bearing holder to make a bearing. It sounds plausible. Has anyone done that before? What are the bearing numbers that you used? Even better does someone know a source for the 70330133 bearing?

Those are called balpak bearings.

Look in the knowledgebase section. There is a topic about them.

BY costly, he means like $300-$400. No wonder sales were so low they were discontinued 10 years ago
