There are many kinds of bearings used for agricultural machinery, including pedestal bearings, pedestal ball bearing units, tapered roller bearings, angular contact ball bearings and units, Deep Groove Ball Bearing, self-aligning roller bearings, spherical plain bearings and some special bearing machinery for agricultural machinery.
Agricultural machinery bearings are usually integrated with flange bearing seats to simplify assembly. If the plow disc is connected to the bearing and installed at a certain angle with the plow surface, the bearing needs to withstand lateral loads, overturning moments, and radial loads. Products used in agricultural machinery include pedestal bearings and bearing pedestal units, Deep Groove Ball Bearing and angular contact ball bearings, tapered roller bearings, hexagonal and square hole bearings, and drive chains.
