Ultra-high-performance oil specially developed for industrial gears and bearings used under harsh conditions.
Industrial Premium Gear Oil "Sartop" protects equipment from various troubles such as seal leaks, dry starts, water contamination, oxidation degradation, and foaming. By pursuing high performance to the extreme through a unique additive blending technology and the use of carefully selected base oils, durability has also been improved. 【Features】 ○ Adhesion: Prevents dry starts even after long periods of inactivity. ○ Improved sealing function: Keeps seals in good condition to prevent leaks. ○ Corrosion and rust suppression: Protects surfaces and shields metals from moisture and acids. ○ Water resistance: Does not attract water, and facilitates the easy discharge of separated water. ○ Anti-foaming: Prevents heat and pressure increases due to foaming and leaks from vents. ○ Long lifespan: Reduces operating temperature increases and suppresses the degradation of the oil itself. ○ Operating temperature: -7 to +135°C (intermittent), -7 to +121°C (continuous).
