Actually, it's not necessary. Agricultural machinery is the roughest thing, using the most ordinary things, without any precision, the simpler the better, and the cheaper the better. So agricultural machinery does not necessarily use bearings with higher precision, the better. Agricultural machinery refers to various types of machinery used in crop planting and animal husbandry production processes, as well as in the initial processing and handling of agricultural and livestock products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland drainage and irrigation machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery, and agricultural transportation machinery. |
