L-HL Anti-oxidation Anti-rust Hydraulic Oil
L-HL15 / 22 / 32 / 46 / 68 / 100 / 150
Features good lubrication, cooling, and sealing performance, maintaining stable system operation under changing working conditions, while offering anti-oxidation, anti-foam, and anti-emulsification properties, suitable for circulation lubrication systems.
Product Description
Product performance: Excellent viscosity-temperature properties ensure good lubrication, cooling, and sealing of hydraulic components under varying operating pressure and temperature conditions; excellent oxidation stability slows oil degradation and extends oil change intervals; excellent foam suppression and air release ensure sensitive, accurate, and stable transmission of static pressure; excellent demulsibility and filterability allow rapid separation of water ingress, minimize filter clogging, and maintain normal lubrication; good compatibility with conventional sealing materials. Application: Primarily used for lubrication of main spindle hydraulic oil tanks and gearboxes of general machine tools, or similar mechanical equipment circulation systems.
