Shell Gadus S5 V110KP 1
An exceptional, next-generation blade bearing grease supporting the latest wind turbine innovations
Shell Gadus S5 V110KP 1 is an outstanding synthetic grease for onshore and offshore wind turbines, delivering a step change in performance.
- Designed for turbines with higher specific load requirements.
- Developed with leading manufacturers and certified by major wind turbine OEMs.
- Offers optimum protection for generator bearings and yaw roller bearings.
In-depth field trials and laboratory tests confirm this grease provides exceptional protection against challenges, including:
Load
Vibration
Low speed
High torque
Low temperature
Pumpability
Corrosion
Shell Gadus S5 V110KP 1 Offers
Dynamic Load Protection
- Challenge: High loads are a complex lubrication challenge for blade bearings, amplified by vibration and low speed active pitching. Wear can occur due to false brinelling, fretting and low speed operating conditions.
- Solution: Grease formulation must strike a difficult balance between base oil quality, special additivation and thickener technology. Shell Gadus S5 V110KP 1 demonstrates the lowest wear and torque levels compared to other greases, resulting in longer bearing life.
Corrosion Protection
- Challenge: Both humidity and condensation will be present in any type of wind turbine operating environment. This makes bearing surfaces vulnerable to rust and corrosion pit formations.
- Solution: Lubricants must maintain a stable film against water ingress. Choice of thickener, base oil, and additives will be critical to product performance.
High Torque Prevention and Pumpability at Low Temperature
- Challenge: Greases with poor pumpability can block lubrication systems, increase the starting torque in bearings, and risk mechanical wear through grease starvation.
- Solution: Formulated with select synthetic base oils and optimised thickener technology ensure grease mobility at arctic temperatures. Choice of thickener, base oil, and additives are critical to product performance.
Shell Gadus S5 V110KP 1 meets the grease requirements of major wind turbine, wind bearing, and lubrication system OEMs. Official documentation of OEM approvals is available upon request.
