EXXONMOBIL® MOBIL™ SHC™ 500 Series oils include Mobil SHC™ 524, 525, 526 and 527 very high performance hydraulic oils formulated from synthesised, wax-free hydrocarbon base fluids combined with a carefully engineered super-stabilised additive system.
They feature exceptionally high quality, wide-temperature, shear-stable hydraulic oils with controlled low-temperature pumpability properties and maximised anti-wear protection for high-pressure vane, piston and gear pumps. Their very high viscosity indexes contribute to their excellent low and high temperature performance making them an excellent choice for equipment subjected to a wide range of start-up and operating temperatures. They exhibit outstanding shear stability allowing their use in high-pressure, high-temperature operating environments for extended periods of time without the loss of critical lubrication characteristics.
The MOBIL™ SHC™ 500 Series oils have been designed to provide excellent wear protection for high-pressure vane, piston and gear pumps operating in a wide range of temperatures and formulated to provide outstanding low- and high-temperature performance and equipment protection up to three times longer than comparable conventional products. They were developed in conjunction with the major OEMs to meet the stringent requirements of severe hydraulic systems using high pressure, high output pumps as well as handling the critical requirements of other hydraulic system components such as close clearance servo-valves and the high accuracy numerically controlled (NC) machine tools.
These products meet some of the most rigorous performance requirements of a wide range of hydraulic system and component manufacturers, using various multi-metallurgy designs, ensuring a single product with exceptional performance characteristics in a wide range of equipment. They are designed to work with systems operating under severe conditions where high levels of anti-wear and film strength protection are needed, yet they are formulated to work where non-anti-wear hydraulic oils are generally recommended.
