Better Protection

Shell Gadus S4 OG lubricants all comfortably exceed the minimum threshold of 120 in the load wear index*, which measures the ability of a lubricant to prevent wear under applied loads.


Shell Gadus S4 OG Outstanding Adhesiveness in Harsh Conditions

To protect effectively, open-gear lubricants must prevent metal-to-metal gear tooth contact, even under sustained and shock loads, in the presence of water and other contaminants. Adhesiveness is critical. Shell Gadus S4 OG lubricants offer: Minimal wash-off, fling-off or squeeze out

(displacement under load).

A highly persistent lubricant film on gear teeth.

Outstanding protection, even in challenging wet or dusty environments.

In water spray-off tests, Shell Gadus S4 OGT showed negligible loss.*

Shell Gadus S4 OG Clear Oil 20000 Advanced Open Gear Lubricant

Shell Gadus S4 OG Clear Oil 20000 is advanced part-synthetic non-bitumastic viscous lubricant specifically developed to satisfy the demands of heavily loaded open gearing.

This product was primarily designed for fixed plant (mills, kilns) for gears in vertical orientation. Shell Gadus S4 OG Clear 20000 is approved and recommended for the main Mills & Kilns OEMs as Metso, FLSmidth and Ferry Capitain.


Shell Gadus S4 OG Clear Oil 20000 Exceeds Load-Carrying Needs

The Shell Gadus S4 OG Clear Oil 20000 helps to prevent damage to gear teeth heavily loaded, for reduced downtime and maintenance costs and extended equipment life. It incorporates: Extreme pressure performance: The high viscosity base oils are combined with extreme pressure additives to give the lubricant

very high film strength and extreme load carrying capability needed for the protection or heavily loaded open gearing.

Ultra-high-viscosity base oils The use of synthetic oil with thickening has produced a lubricant with high viscosity index, which

provides good pumpability at low temperatures while maintaining high viscosity at elevated temperatures.

Easier gear inspections: Static and dynamic inspections are much easier to view the gear condition without cleaning off the

grease or oil, as the lube film is clear, can inspect the gearing through the lube film

Shell Gadus S4 OG Clear Oil 20000 meets the essential 800-kg four-ball weld load specification.

Success Case (Demonstrated Value Records DVRs)


Success Case 01 Chaneme (Hitachi Dealer) Shell Gadus S2 OG 85 Pins & Bushes Hitachi Excavators

1 2 3 CHALLENGE SOLUTION OUTCOME

VALUE 4

Chaneme (Hitachi Dealer in Colombia) in coal mine in Calenturitas Colombia maintains 5 excavators Hitachi EX 3600-5.

Chaneme wanted to increase the pins & bushes life beyond the current 4,000 hrs.

Shell, through Shell LubeExpert, identified the failures causes and proposed the use of a high-performance grease (Shell Gadus S2 OG 85).

By identifying the failures causes, implementation of a routine inspection process of lubrication system and critical components, together with the application of high performance grease (Shell Gadus S2 OG 85) the pins and bushes life increased from 4,000 hrs to 16,000 hrs.

Savings of over USD 600,000.00 with increase of productivity and with life extension of pins and bushes

Increased pins and bushes life from 4,000 hrs to 16,000 hrs

The savings indicated are specific to the calculation date and mentioned site. These calculations may vary from site to site, depending on the application, the operating conditions, the current products being used, the condition of the equipment and maintenance practices.


Success Case 02 Albian Sands Energy Shell Gadus S4 OGK/OGXK Saddle Block Liners


VALUE 4

Albian Sands Energy in Fort McMurray Canada operates 10 Bucyrus 495 HF shovels.

The key challenge was cold temperature and the ability of the product to not just pump through the system, but be robust enough that it provided the best lubrication during winter.

Shell, through Shell LubeExpert, made a detailed analysis and inspection of the application and proposed the use of a high-performance lubricant for saddle block liners, open gears, boom and revolving frame (Shell Gadus S4 OGK/OGXK).

By implementing of a routine inspection process of the lubrication system and the critical components of the shovels, together with the application of high performance grease (Gadus S4 OGK/OGXK) the saddle block liners life achieved over 32,000 hrs against a estimated life of 10,000 hrs.

Savings of over USD 1,800,000.00/year with increase of productivity and with life extension of saddle block liners

Increased saddle block liners life from 10,000 hrs to 32,000 hrs



Success Case 03 Iron Ore Mining in Brazil Shell Gadus S3 V220C 2 Bearing of the Bucket Wheel


VALUE 4

Iron ore mining in Brazil operates a ThyssenKrupp 5PA5A reclaimer.

The challenge was increase the bearing of the bucket wheel life beyond the current 4,000 hrs.

Shell, through Shell LubeExpert, identified the failures causes and proposed the use of a high-performance grease (Shell Gadus S3 V220C 2).

By implementation of a routine inspection process of the lubrication system, resizing of bearings sealing and application of a high performance grease (Gadus S3 V220C 2), the bearing life increased from 4,000 hrs to over 8,600 hrs.

Savings of over USD 2,000,000.00/year with increase of productivity and with life extension of the bucket wheel bearing

Increased bucket wheel bearing life from 4,000 hrs to 8,600 hrs

Significantly reduction the reclaimer unavailability and therefore increased its productivity



Success Case 04 The Lagunas Norte Mine in Peru Shell Tactic EMV Conveyor Belt Bearings


VALUE

Lagunas Norte was previously using Shell Gadus S2 V220 2 grease for manual lubrication. The greasing schedule was not always completed, and irregular lubrication, together with contamination by dirt, dust and water, was causing the production belt bearings to wear. Consequently, the company experienced unscheduled stoppages and production losses.

Shell Lubricants recommended the installation of a Shell Tactic EMV automated grease dispensing unit pre-filled with Shell Gadus S3 T220 2 grease, and staff training using the Shell LubeCoach service. Shell Tactic EMV lubricating units were installed at two critical production points to supply precise, reliable and regular amounts of grease to the machines.

After implementing the recommended solution, Lagunas Norte experienced: a decrease in manual lubrication time that enabled technical staff to attend previously neglected areas. the elimination of premature bearing failures through reliable and regular lubrication. peace of mind from knowing that the greasing was automated and set specifically for the machines requirements.

By identifying the mines need for greasing support and a premium grease to perform well in a high-contamination environment, Shell was able to recommend a solution that met both requirements. Lagunas Norte reported a potential annual saving of US$167,417 as a result of implementing the solution.
