Mobil SHC 639 Gear and Bearing Oil

The Mobil Mobil SHC 639 is an exceptional performance gear and bearing oil formulated with proprietary Mobil SHC technology. This synthetic lubricant features excellent low-temperature properties and improved air release. It is highly resistant to mechanical shear, maintaining its viscosity even under heavy loads in gear and bearing systems. The oil's low traction coefficient, derived from its base stock structure, reduces fluid friction in sliding mechanisms, leading to lower operating temperatures and enhanced gear efficiency. Controlled laboratory tests have shown up to a 3.6% improvement in energy efficiency compared to mineral oils. Key features include superb high-temperature thermal and oxidation resistance, which helps extend equipment operating capability and oil life, thereby reducing maintenance costs and minimizing deposits for trouble-free operation. Its high viscosity index and absence of wax ensure consistent viscosity and film thickness at high temperatures, while also providing exceptional low-temperature performance, including during start-up. The oil offers high load-carrying capability for equipment protection and extended service periods. Additionally, its balanced additive combination ensures excellent rust and corrosion prevention, water separability, foam control, and air release properties, contributing to operational efficiency and reduced costs. The Mobil SHC 600 Series oils maintain good compatibility with seals and other materials commonly found in equipment lubricated with mineral oils, making them suitable for a wide range of industrial applications, not only for high-temperature challenges but also for their overall performance benefits.
