宜昌当阳-远安壳牌齿轮油-导轨油68号供应部L-CKC中负荷齿轮油是根据国家标准GB5903-2011定义的工业闭式齿轮润滑剂，专用于齿面接触应力小于1100N/mm²的工业齿轮系统。该油品采用石油润滑油基础油或合成润滑油为基材，添加硫-磷型极压抗磨剂等复合添加剂调配而成，具有适度的粘度特性、抗乳化性及粘温性能。技术体系经历了从硫-氯型到硫-磷型抗磨剂的技术迭代，适用于冶金轧机、矿山机械等中等负荷齿轮箱系统。在产品体系中定位介于L-CKB（一般负荷）与L-CKD（重负荷）齿轮油之间，国内外主要润滑油品牌均有对应产品线L-CKC load gear oil is an industrial closed gear lubricant defined according to the national standard GB5903-2011, specifically designed for industrial gear systems with tooth contact stress less than 1100N/mm ². This oil product is formulated using petroleum lubricating base oil or synthetic lubricating oil as the base material, with the addition of composite additives such as sulfur phosphorus extreme pressure anti-wear agents. It has moderate viscosity characteristics, emulsion resistance, and viscosity temperature performance. The technical system has undergone technological iterations from sulfur chlorine type to sulfur phosphorus type anti-wear agents, and is suitable for medium load gearbox systems such as metallurgical rolling mills and mining machinery. Positioned between L-CKB (general load) and L-CKD (heavy load) gear oils in the product system, major lubricant brands both domestically and internationally have corresponding product lines
