Description
Castrol Hyspin AWS 68 is a mineral oil-based hydraulic fluid formulated with an anti-wear additive system to provide reliable lubrication and protection in industrial hydraulic equipment. It offers good thermal and oxidative stability, corrosion protection, water separation and resistance to sludge and deposit formation.
Features and Benefits
-
Anti-wear protection: Helps reduce wear on hydraulic pumps and other moving components.
-
Oxidation stability: Helps minimise oil degradation, sludge and deposits.
-
Corrosion protection: Protects ferrous and yellow metal components.
-
Water separation: Helps separate water from the oil to support reliable system operation.
-
Filterability: Supports hydraulic system cleanliness and efficient filtration.
-
Foam control: Helps minimise foam formation during operation.
-
Thermal stability: Helps maintain lubricant performance under normal operating conditions.
Applications
-
Industrial hydraulic systems requiring ISO VG 68 anti-wear hydraulic oil.
-
Hydraulic presses and machine tools.
-
Injection moulding equipment.
-
Industrial machinery and selected gearboxes where the equipment manufacturer permits this type of oil.
-
Bearing lubrication systems requiring an appropriate anti-wear hydraulic fluid.
Always check the equipment manufacturer's viscosity and performance requirements before use.
