Shell Gadus S4 OGH 160 is recommended for the lubrication of all types of grinding mills and kilns.

Shell Gadus S4 OGH 160 may be applied manually or by conventional centralized automatic lubrication systems.
Features and Benefits N/A Exceptional Physical and Mechanical Stability - Shell Gadus S2 OG 40 retains its natural protective properties over its long working life.

Excellent Anti-Wear Performance - At working temperatures, speeds and pressures, Shell Gadus S2 OG forms a protective cushion between the large gear (girth, bull, etc.) and pinion teeth.

Superb Load Carrying Capacity - Molybdenum disulfide and other solid lubricants combine to reduce tooth contact zone temperatures, reduce gear surface pitting and alleviate 'stick-slip' conditions.

Water Repellent - Effectively resists water 'wash-off' by immersion or spray.

Corrosion Protection - Protects metal srufaces from corrosion in hostile environments such as salt-water conditions. Repels dirt and dust. 

Environment Compliance - Lead and solvent have not been added intentionally to Shell Gadus S2 OG 40. 		N/A Exceptional Physical and Mechanical Stability - Shell Gadus S2 OG 40 retains its natural protective properties over its long working life.

Environment Compliance - Lead and solvent have not been added intentionally to Shell Gadus S2 OG 40. 		N/A Excellent Load Carrying Capacity Under Severe Operation Conditions - Grease contains selected components to ensure excellent resistance to shock and permanently heavy loads.

Very High Mechanical and Thermal Stability - Grease thickener structure is designed to resist mechanical stress and high temperature.

Withstanding Severe Operation Conditions - Like dust and dirt contamination, water, and changes in temperature. Shell Gadus S4 OG Multi-Season is optimized for use in ambient temperatures from -20 C to 40 C. 

Maintain Adhesive Characteristic Over Time - Thanks to advanced polymer technology ensuring durable protection. Forms a dark coating on metal surfaces that is adhesive and highly water resistant.

Low Friction - Selected components ensure low fricition characteristics, lower energy consumption and wear reduction.

Environmental Compliance - Shell Gadus S4 OG Multi-Season is formulated without chlorinated solvent or lead. 

Operation Temperature - General maximum operating temperature 90 C if not restricted by other equipment/application requirements. 		N/A
  • Shell Gadus S4 OGH 160 lubricant represents the latest scientific breakthrough technology. Unique feature provides a durable protective coating to metal surfaces without the use of bitumen, solvents or heavy metals. 
  • Shell Gadus S4 OGH 160 generates a tough, durable film on metal surfaces, which minimizes metal-to-metal contact and wear. Lubricant consumption is reduced by as much as 40% compared to traditional open gear lubricants of the fluid type.
  • Shell Gadus S4 OGH 160 contains graphite and MoS2. Special additive technology greatly enhances the effectiveness of graphite and MoS2. This unique combination enhances the separation of extremely loaded gear teeth and creates a durable protective film on the contact surfaces of machine components.
  • Reduced Maintenance/Housekeeping: Shell Gadus S4 OGH 160 retains its natural protective properties and remains pliable over its long working life. Resists drying out in gear teeth or shrouds even in extremely dusty conditions.
  • Excellent Anti-Wear Performance: Molybdenum disulfide and other solid lubricants combine to reduce tooth contact zone temperatures, reduce gear surface pitting and alleviate "stick-slip" conditions.
  • Superb Load Carrying Capacity: Shell Gadus S4 OGH 160 with its unique blend of high viscosity base oils and polymer forms a protective cushion between gear teeth and resists "fling off," "squeeze out," and oil separation.
  • Water Resistant: Effectiviely resists water "wash-off" by immersion or spray.
  • Reduced Lubricant Consumption: Shell Gadus S4 OGH 160 forms a tenancious lubricant film, which allows a reduced application rate in comparison to conventional gear lubricants.
  • Environmental Compliance: Lead and solvent haven't been added intentionally to Shell Gadus S4 OGH 160, combined with the ability to decrease usage reduces environmental concerns.
  • Corrosion Protection: Protects metal surfaces from corrosion in hostile environments such as salt-water conditions. Repels dirt and dust.
