Product Overview
Mobil SHC 629 is an exceptional performance synthetic gear and bearing oil formulated from proprietary PAO base stocks for demanding enclosed gear and bearing applications requiring ISO VG 150 lubrication. Part of the Mobil SHC 600 Series, it delivers outstanding service across a uniquely wide range of applications — from industrial enclosed gearboxes and Flender-approved drives through to oil-flooded rotary screw compressors handling natural gas, field gas and CO2, and Rolls-Royce Marine approved thruster applications.
The PAO synthetic base stock provides a viscosity index of 166, a pour point of -48°C and TOST oxidation life exceeding 10,000 hours — enabling extended drain intervals, reliable cold-start performance in remote or cold-climate applications, and superior protection at elevated operating temperatures compared to equivalent mineral gear oils at ISO VG 150.
Note: Mobil SHC 629 has an orange colour, distinguishing it visually from mineral gear oils and the clear Mobilgear 600 XP Series. Always confirm the required ISO VG grade and application type from the equipment nameplate before ordering.
Key Performance Benefits
Exceptional Oil Life
RPVOT of 2,500 minutes and TOST of 10,000+ hours — outstanding oxidation resistance that enables extended drain intervals in enclosed gearboxes and compressors operating in continuous duty cycles.
Wide Temperature Range
Viscosity index of 166 and pour point of -48°C — exceptional cold-start performance for remote, elevated or cold-climate applications. Maintains adequate film thickness at elevated operating temperatures without viscosity thinning.
Energy Efficiency
Low traction coefficient of the PAO base stock reduces fluid friction in gear contacts and rolling element bearings — producing lower operating temperatures and measurable energy savings up to 3.6% vs mineral equivalents in circulating and gear applications.
Gas Compressor Capability
Approved for oil-flooded rotary screw compressors compressing natural gas, field gas gathering, CO2 and other process gases used in the natural gas industry — a unique dual capability not available in most industrial gear oils.
Shear Stability
Virtually no viscosity loss under mechanical shear in heavily loaded gear and high-shear bearing applications — maintains ISO VG 150 protection throughout the service interval unlike thickened mineral oils.
Rust, Corrosion & Water Resistance
Passes ASTM D665 Procedure B rust test. Excellent demulsibility, foam control and air release performance — critical for marine thruster applications (Rolls-Royce approved) and offshore gear drives exposed to seawater contamination.
Typical Applications
Mobil SHC 629 covers an exceptionally wide range of applications for a single ISO VG 150 grade — industrial enclosed gearboxes, gas compressors and marine thrusters. Always confirm the correct product and grade from the equipment nameplate or OEM manual before ordering:
