Product Information

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.

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
