Agricultural machinery and equipment are characterized by relatively dirty operating environments, requiring high waterproof and dustproof performance for bearing products, and being able to adapt to extreme conditions (such as outdoor conditions with large temperature differences or environments with severe mud, water, and dust) for normal operation. Agricultural bearings are mostly sealed with double or triple lip seals, which can effectively isolate the entry of water and dust

Depending on the installation method, products with a circular, square, or hexagonal inner ring and a cylindrical or spherical outer ring can be selected
