SHC 639 Synthetic Gear and Bearing Oil

The Mobil SHC 639 is an exceptional performance synthetic gear and bearing oil engineered to deliver outstanding service life, robust equipment protection, and problem-free operation, ultimately increasing customer productivity. This scientifically formulated lubricant utilizes the latest proprietary Mobil SHC technology to offer a balanced performance profile suitable for challenging applications across a wide temperature range. Key features include excellent low-temperature properties and improved air release, particularly in lower viscosity grades. The oil demonstrates significant resistance to mechanical shear, ensuring virtually no loss of viscosity even in heavily loaded gear and high-shear bearing environments. Its low traction coefficient, derived from the unique molecular structure of its base oils, results in reduced fluid friction. This friction reduction leads to lower operating temperatures and improved gear efficiency, potentially decreasing power consumption. In controlled laboratory testing, Mobil SHC 600 Series products have shown up to a 3.6% improvement in energy efficiency compared to mineral oils. Furthermore, the formulation provides superior resistance to oxidation and deposit formation at elevated temperatures, along with exceptional protection against rust and corrosion, anti-wear properties, and good demulsibility, foam control, and air release characteristics. It also ensures multi-metal compatibility and maintains good compatibility with common seals and other materials typically found in equipment lubricated with mineral oils. The Mobil SHC 600 Series oils are designed for a broad spectrum of equipment, serving not only as high-temperature problem solvers but also offering a host of other benefits. The advanced synthetic formulation provides excellent thermal and oxidative stability, helping to extend the operating capabilities of equipment at high temperatures, promote long oil life, reduce maintenance costs, and minimize deposits for trouble-free operation and extended filter life. Its high viscosity index and wax-free nature ensure consistent viscosity and film thickness at high temperatures, while also enabling exceptional low-temperature performance, including start-up. The low traction coefficient contributes to reduced friction and increased efficiency in sliding mechanisms, potentially lowering power consumption and steady-state operating temperatures, and minimizing micro-slip effects in rolling-contact bearings to extend their life. The high load-carrying capability protects equipment, extends its service life, and helps minimize unscheduled downtime. A balanced additive combination ensures excellent rust and corrosion prevention, water separability, foam control, and air release performance, contributing to problem-free operation and reduced operating costs.
