Shell Gadus S5 V142W 00
Shell Gadus S5 V142W 00 is an advanced semi-fluid gear grease developed to provide long service life and reliable lubrication performance in small industrial gearboxes. The grease is formulated using a synthetic polyglycol base oil combined with a lithium soap thickener. This advanced formulation provides excellent load carrying capability, improved efficiency and strong oxidation stability, enabling the lubricant to operate effectively under demanding industrial conditions.
A key advantage of Shell Gadus S5 V142W 00 is its ability to provide long-life lubrication in gearboxes that are often designed to operate for extended periods without maintenance. The semi-fluid grease consistency allows it to flow easily within the gearbox while maintaining a protective lubricating film on gear surfaces. This characteristic makes it suitable for “lubricated for life” gearbox applications where long-term reliability and reduced maintenance requirements are essential.
The grease also contributes to improved operating efficiency. The synthetic polyglycol base oil used in the formulation provides excellent frictional performance, helping reduce friction between gear surfaces during operation. Lower friction levels can reduce power consumption and help lower the bulk lubricant temperature within the gearbox. These characteristics support more efficient equipment operation while reducing mechanical stress on gearbox components.
Shell Gadus S5 V142W 00 also offers excellent load carrying capability. According to gear scuffing tests conducted using the IAE gear rig, the base oil provides significantly higher load carrying performance compared with equivalent viscosity mineral oils. This allows the lubricant to maintain a durable lubrication film between gear teeth even when gearboxes operate under demanding loads and continuous duty conditions.
Another important feature of the grease is its excellent low temperature performance. Gearboxes operating in cold environments often experience increased starting torque due to lubricant stiffening. Shell Gadus S5 V142W 00 maintains good flow characteristics at low temperatures, helping reduce start-up torque and preventing lubrication starvation caused by grease channelling. This property supports reliable gearbox operation in a wide range of ambient conditions.
Shell Gadus S5 V142W 00 is particularly recommended for lubrication of small industrial gear units and worm gear systems, especially those using steel and tin-bronze gear combinations. The grease has been successfully used in gearboxes manufactured by leading equipment producers such as David Brown, SEW and Leroy-Somer, demonstrating its reliability across a wide range of industrial operating conditions.
Physical characteristics include NLGI 00 consistency with a lithium thickener and synthetic polyglycol base oil. The grease has a base oil viscosity of approximately 142 mm²/s at 40°C and 23 mm²/s at 100°C. Worked cone penetration is approximately 410 (0.1 mm) and the dropping point is around 185°C. The grease is suitable for operation at continuous bulk lubricant temperatures up to approximately 130°C while maintaining stable lubrication performance.
