SHC 634 Synthetic Gear and Bearing Oil

The Mobil SHC 634 is an exceptional performance synthetic gear and bearing oil engineered to deliver outstanding service life, equipment protection, and problem-free operation, ultimately boosting customer productivity. Formulated with the latest proprietary and patent-pending Mobil SHC technology, these oils provide a balanced performance profile for demanding applications across a wide temperature range. Key features of the Mobil SHC 634 include superb high-temperature thermal and oxidation resistance, which helps extend equipment operating capability and prolong oil life, thereby reducing maintenance costs. Its high viscosity index and absence of wax ensure maintained viscosity and film thickness at high temperatures, while also enabling exceptional low-temperature performance, including during start-up. The oil's low traction coefficient contributes to reduced friction and increased efficiency in sliding mechanisms like gearing, potentially lowering power consumption and steady-state operating temperatures. It also minimizes the effects of micro-slip in rolling contact bearings, which can extend their operational life. This synthetic gear oil offers high load-carrying capability to protect equipment and extend service periods, minimizing unexpected downtime. Its balanced additive system provides excellent protection against rust and corrosion, along with superior water separability, foam control, and air release properties. The Mobil SHC 634 is compatible with seals and other materials commonly found in equipment lubricated with mineral oils. It meets AGMA EP 9005-E02 specifications and has a viscosity of ISO 460, a pour point of -30°C, and a flash point of 228°C. Mobil SHC 600 Series lubricants are recognized globally for their innovation and performance. These synthetic products are molecularly designed and have been developed through close collaboration with key Original Equipment Manufacturers (OEMs) to ensure exceptional performance in evolving industrial equipment designs. Laboratory and rig tests, as well as OEM confirmations, have shown potential for energy efficiency improvements up to 3.6% compared to mineral oils, particularly in equipment with high mechanical losses like high-ratio worm gears.
