Agricultural equipment subjects bearings to abrasive dust and mud, water spray, shock loads, and long harvest runs followed by months of storage. Core machines include tractors, combine harvesters, tillage implements, balers, and sprayers. Typical bearing families are sealed insert bearings in pillow/flange/take-up housings, agri wheel hubs (round/square/hex bores), spherical or tapered roller bearings for hubs and drives, and deep-groove ball bearings for motors and augers. Key design priorities: high radial/axial capacity, misalignment tolerance, reinforced sealing, corrosion-resistant materials/greases, and relubable heavy-duty housings.
