Mobil SHC™ 500 Series hydraulic oils

View all products in mobil eal hydraulic oil

Our Mobil SHC 500 Series synthetic hydraulic oils are designed to provide excellent wear protection for high-pressure vane, piston and gear pumps operating in a wide range of temperatures. They are formulated to provide outstanding low- and high-temperature performance and equipment protection up to three times longer than comparable conventional products.

Mobil SHC 500 Series hydraulic oils can help reduce energy consumption by up to 6.2 per cent compared to conventional hydraulic oils*. They can also help:

Extend filter life
Improve hydraulic system efficiency
Increase system cleanliness and durability
Decrease machine maintenance
Extend oil drain intervals

Results are based on controlled laboratory tests and may vary depending on equipment type and condition and operating conditions.

Features and Benefits

The Mobil SHC 500 Series hydraulic oils exhibit outstanding low and high temperature performance helping to provide an extra margin of equipment protection above and beyond the capabilities of comparable mineral oil-based products. Their excellent oxidation resistance allows extension of oil and filter change intervals while assuring exceptionally clean systems and trouble-free operation. Their high level of anti-wear properties and excellent film strength characteristics result in exceptional equipment performance that helps prevent unplanned equipment breakdowns, and maximize equipment uptime, which can enable potential improvements in production capacity. Their controlled demulsibility permits the oils to work well in systems contaminated with small amounts of water yet readily separate large amounts of water.

Features	Advantages and Potential Benefits
Design-Specific Synthetic Base stock	Helps extend service intervals Cleaner system and reduced close-tolerance valve sticking compared to conventional products Helps improve filterability
Innovative Keep Clean Properties	Helps reduce system deposits and potential sludging Helps protect critical components such as servo-valves, improving system response and minimizing valve sticking
Exceptional Anti-wear	Helps reduce wear of components Helps protect systems using various metallurgy
High Viscosity Index	Wide temperature range performance Helps to ensure equipment protection at cold start-up temperatures Helps protect system components at high operating temperatures
Outstanding Oxidation Stability	Helps provide long oil and equipment life, which can extend filter life
Excellent Corrosion Protection	Helps prevent internal hydraulic system corrosion Helps reduce the negative effects of moisture in systems Helps provide corrosion protection of multi-metallurgy component designs
Very Good Multi-metal Compatibility	Helps optimize inventory requirements
Meets a Wide Range of Equipment Requirements	One product can replace several helping to optimize inventory requirements and mitigate potential product misapplication
Excellent Air Separation Characteristics	Helps reduce foaming and it's negative effects
Controlled Demulsibility	Provides systems protection and lubrication where small quantities of moisture are present Readily separates larger quantities of water

Applications

Hydraulic systems prone to deposit build-up such as sophisticated Numerically Controlled (NC) machines, particularly where close clearance servo-valves are used
Systems employing multi-metal component designs
High pressure vane, piston and gear pumps
Systems where cold start-up and / or very high operating temperatures are typical
Where small amounts of water are unavoidable
In systems containing gears and bearings
Systems requiring a high degree of load-carrying capability and anti-wear protection
Applications where thin oil-film corrosion protection is an asset such as in systems containing moisture
