1. Before installation, the oil seal should be smeared with an appropriate amount of lithium-based ester added with molybdenum disulfide between the lips to prevent dry abrasion of the lips when the shaft starts up instantly, affecting the interference of the lips, and should As soon as possible, assemble.
