Shell Gadus S3 V770D 1
Shell Gadus S3 V770D 1 is a premium heavy-duty grease developed to provide dependable lubrication and protection for slow and very slow moving bearings operating under extremely severe conditions. The grease is formulated using high viscosity index mineral base oils combined with a lithium complex soap thickener and specially selected solid lubricants. This advanced formulation delivers excellent load carrying capability, improved resistance to shock loading and reliable lubrication performance in heavy industrial equipment.
A key advantage of Shell Gadus S3 V770D 1 is its ability to withstand extremely high loads and shock conditions. Many heavy-duty industrial machines operate under continuous high loads and frequent shock loading, which can cause rapid wear or lubricant failure when conventional greases are used. The inclusion of solid lubricants in the formulation helps maintain a protective film between metal surfaces even under extreme mechanical stress. This protective layer helps prevent metal-to-metal contact and significantly reduces the risk of premature bearing failure.
The grease also provides excellent adhesion and resistance to wash-out. Industrial equipment operating in sectors such as mining, steel production and cement manufacturing is frequently exposed to water, dust and other contaminants. Shell Gadus S3 V770D 1 is formulated to adhere strongly to metal surfaces, helping the grease remain in place even in wet or contaminated environments. This strong adhesion reduces grease loss and helps ensure reliable lubrication over extended service intervals.
Another important feature of the product is its mechanical stability under vibration. Equipment such as rock crushers, conveyors and heavy processing machinery often generates severe vibration during operation. Shell Gadus S3 V770D 1 maintains its structural consistency even under these conditions, ensuring that lubrication remains effective throughout long operating cycles. This stability helps reduce grease consumption and supports lower maintenance requirements.
The grease also performs well at elevated temperatures. The lithium complex thickener system provides strong thermal stability and helps prevent grease softening or leakage during high temperature operation. This contributes to extended lubrication intervals and reduced downtime for maintenance. The grease’s ability to resist melting helps maintain lubrication protection even in demanding operating environments.
Shell Gadus S3 V770D 1 is recommended for slow and very slow moving heavy-duty plain and rolling element bearings operating under severe loads, shock conditions and water-rich environments. Typical applications include equipment used in the steel, mining, cement and chemical industries. It is also suitable for flexible gear couplings operating at speeds above 200 rpm where strong adhesion and shock load protection are required.
Physical characteristics include NLGI grade 1 consistency with a lithium complex thickener and mineral base oil. The grease has a base oil viscosity of approximately 770 mm²/s at 40°C and 39 mm²/s at 100°C. Worked cone penetration is approximately 320 (0.1 mm) and the dropping point is around 240°C. These characteristics support reliable lubrication across a typical operating temperature range of approximately –20°C to +150°C.
