In the agricultural machinery industry, bearing rubber is primarily used to protect bearings, preventing dust, dirt, and water infiltrating from outside, thereby extending the machinery's lifespan. Rubber seals, with their elasticity and wear resistance, reduce friction and retain lubricating oil, making them suitable for rotating components in equipment such as tractors and harvesters. Especially in dusty or humid agricultural environments, bearings rubbers significantly enhance efficiency and durability while reducing maintenance costs, making them become indispensable key components in agricultural machinery.
