Product Introduction:
Anti-Wear Hydraulic Oil is a high-performance lubricant engineered for modern industrial hydraulic systems. Formulated with refined base oils (mineral, PAO, or ester) and advanced zinc-containing (Zn) anti-wear additive packages, it delivers exceptional wear protection, oxidation stability, and filtration performance. This product provides comprehensive lubrication and protection for hydraulic pumps (vane, piston, gear), motors, cylinders, valves, and piping systems under demanding conditions of high pressure, high speed, wide temperature ranges, and precision servo-valve control. It effectively minimizes component wear, prevents rust, inhibits sludge formation, and maintains system cleanliness. Widely used in construction machinery (excavators, cranes), injection molding machines, die-casting machines, machine tools, metallurgical equipment, marine deck machinery, power generation equipment, and automated production lines, it is the critical choice for ensuring efficient, reliable, and long-lasting hydraulic system operation while reducing maintenance costs and downtime.
Product Features:
Outstanding Anti-Wear Protection: Core feature! Contains high-performance anti-wear additives that form a durable protective film on metal surfaces under high load and boundary lubrication conditions. Significantly reduces wear, scuffing, and fatigue failure in critical components like pumps and motors, extending equipment life. Especially meets the stringent requirements of high-pressure vane and piston pumps.
Excellent Oxidation Stability: Possesses strong resistance to thermal and oxidative degradation, effectively inhibiting abnormal viscosity increase, acid number rise, and the formation of sludge and varnish. Maintains fluid cleanliness over extended periods, prolongs drain intervals, and protects precision components (e.g., servo valves).
Superior Filtrability & Cleanliness Retention: Good solvency and detergency/dispersancy effectively suspend fine contaminants and allow smooth passage through high-efficiency filters (e.g., β₅ ≥ 75), preventing premature filter clogging. Maintains system fluid cleanliness, safeguarding sensitive hydraulic components (especially vital in closed-loop systems with proportional/servo valves).
Excellent Air Release & Anti-Foaming Properties: Rapidly releases entrained air, preventing pump cavitation damage. Effectively suppresses foam generation and quickly dissipates foam, ensuring continuous and stable oil films, avoiding lubrication issues, efficiency loss, and excessive oil temperature rise.
Good Demulsibility & Water Separability: Quickly separates free water contamination, preventing stable emulsion formation. Avoids issues like rust, lubrication failure, accelerated oil oxidation, and valve sticking caused by water.
Excellent Rust & Corrosion Inhibition: Provides comprehensive protection for ferrous and non-ferrous metal surfaces, preventing rust and corrosion in damp environments or when water contamination occurs.
Optimum Viscosity & High Viscosity Index: Selected viscosity grades (e.g., ISO VG 32, 46, 68) ensure effective oil film formation across operating temperatures for proper lubrication and sealing. High Viscosity Index guarantees smooth low-temperature starting (good fluidity) and sufficient viscosity at high temperatures (pressure maintenance).
Good Seal Compatibility: Compatible with common hydraulic seal materials like Nitrile (NBR), Fluorocarbon (FKM), and Polyurethane (PU), preventing excessive seal shrinkage, swelling, hardening, or degradation, thereby reducing leakage risks.
Excellent Shear Stability: Highly resistant to mechanical shearing forces; viscosity index improvers resist permanent breakdown. Maintains stable viscosity over long service life, ensuring consistent system pressure and reliable lubrication.
