Bearings are the "core joints" for the efficient and reliable operation of agricultural machinery. In tractors, harvesters, and other equipment, they support the transmission system, running gear, and key operating components, withstanding heavy loads and impacts in harsh environments such as mud, dust, and moisture. High-quality bearings significantly improve the operating efficiency, durability, and reliability of agricultural machinery, reducing downtime due to malfunctions. This directly impacts the smooth progress of agricultural production and cost control, making them a crucial guarantee for the stable and efficient productivity of modern agricultural equipment.
