Tena-Film SP-1 Silent Chain Oil is a premium chain lubricant developed to reduce wear, elongation, and noise in high-speed chain drive systems. Formulated with a unique blend of extreme oiliness additives, colloidal molybdenum disulfide, thermally stable organo-zinc anti-wear additives, and high-viscosity-index paraffinic base oils, SP-1 rapidly penetrates chain components to provide superior lubrication and protection. The formulation is further enhanced with oxidation inhibitors, rust inhibitors, pour point depressants, and anti-foam additives to ensure long service life. Designed for enclosed oil-bath chain drive units, SP-1 is effective for both silent chains and roller chains operating under demanding industrial conditions.
