Shell Naturelle S4 Stern Tube Fluid 100

Shell Naturelle S4 Stern Tube Fluid 100 is a non-emulsifying synthetic fluid specifically developed for use in stern tubes. Manufactured from fully saturated esters, Shell Naturelle S4 Stern Tube Fluid 100 is designed to offer superior lubrication performance while also being readily biodegradable and having low ecotoxicity.

Designed to offer superior lubrication performance

Fully saturated esters ensure excellent resistance to oxidation and hydrolysis while offering high-temperature thermal stability.

Excellent hydrolytic stability

A non-emulsifying fluid with excellent water separation and anti-foaming characteristics that helps to maintain equipment performance.

Environmentally considerate

  • EU Eco Labelled
  • Independently certified as VGP compliant

Increased wear protection

Ashless (zinc-free) additives provide protection over a wide range of conditions.

Approvals from leading stern tube and seal manufacturers include*

  • SKF Blohm + Voss Industries
  • Wärtsilä Propulsion
  • Kemel
  • Aegir-Marine

Shell Naturelle Fluid HF-E 46 and 68

Cutting Operating Costs

Hydraulic fluids that fail to protect your equipment from wear and corrosion can increase maintenance costs and reduce equipment availability. Shell Naturelle HF-E helps to lower maintenance costs by offering excellent wear protection over a wide temperature range. The naturally high shear stable viscosity index (VI) of Shell Naturelle HF-E helps to deliver responsive performance from cold start to full-load, heavy-duty operation.

Shell Naturelle Fluid HF-E is blended from synthetic base stocks with a naturally high VI of 180–190. The absence of viscosity modifier additives means the fluid is shear stable (i.e., there is no loss of viscosity control under high shear operating conditions) and offers multigrade performance with no loss of VI during use. The viscosity–temperature curve is much flatter than that of conventional hydraulic fluids.

Shell Naturelle S4 Gear Fluid 68, 100 and 150

Prematurely worn components can mean additional maintenance costs and reduced equipment availability. Shell Naturelle S4 Gear Fluid can help to lower maintenance costs by offering outstanding anti-wear and load-carrying performance through their high-quality, synthetic ester base fluid and advanced non-toxic anti-wear additives.

If water and air contaminate your oil, its ability to reduce friction and keep your gears working efficiently may be compromised. Shell Naturelle S4 Gear Fluids help to cut operating costs by maintaining system efficiency through their excellent water separating, load-carrying and anti-wear characteristics.

Shell Naturelle S4 Gear Fluid meets industry standard DIN 51517/3 CLP-E, including full water separation in less than 30 minutes according to DIN ISO 6614.

Longer Service Life

Fully saturated esters ensure excellent resistance to oxidation and hydrolysis while offering high-temperature thermal stability. Shell Naturelle S4 Gear Fluid offers the potential to extend oil service life compared with conventional mineral gear oils.

Load Carrying and Wear Protection 

Shell Naturelle S4 Gear Fluid is formulated to have excellent loadcarrying capacity and anti-scuffing performance. Advanced non-toxic additives provide protection over a wide range of conditions and ensure long component life, even under shock-loading conditions. All Shell Naturelle S4 Gear Fluid grades pass the FZG load test above load stage 13 according to ISO 14635 A20.

Shell Naturelle S2 Wire Rope Lubricant A

Lubricants with poor resistance to water wash-off may fail to protect your equipment, which means there is an increased likelihood of additional costs through unplanned maintenance or equipment downtime.

Shell Naturelle S2 Wire Rope Lubricant A is designed for wire ropes, open gears and other deck equipment. It has excellent adhesion properties and is formulated with a selected blend of additives to offer superior extreme-pressure and anticorrosion protection in the most challenging of environments.

Low-cost lubricants can be poor value if they fail to stay where you need them. Shell Naturelle S2 Wire Rope Lubricant A offers high resistance to water wash-off owing to its outstanding adhesion properties. This can help to cut product consumption and labour costs, thereby reducing the cost of keeping your mooring and crane wires protected and working efficiently.

Extreme Pressure and Anti-Wear 

Specially selected solid lubricants and additives protect components from excessive wear, even under heavy loads.

Excellent Corrosion Protection

Shell Naturelle S2 Wire Rope Lubricant A is formulated to include special anti-corrosion additives to offer enhanced protection from corrosion, even under the influence of seawater. In an SKF EMCOR test for a period of one week, there was no sign of corrosion.

Readily Biodegradable

Shell Naturelle S2 Wire Rope Lubricant A achieves the OECD 301 F requirement of >60% degradation within 28 days and is made from >60% renewable raw materials classed as minimally toxic and non‑bioaccumulative.

Shell Naturelle S5 Grease V120P 2

Shell Naturelle S5 Grease V120P 2 is a biodegradable grease for use in rudder bearings; applications such as slow speed plain bearings (slower than 500 rpm) and high-speed ball and roller bearings (up to 2,000 rpm) that require an extreme-pressure grease; and in routine greasing of deck equipment. The grease is based on a lithium hydroxystearate soap thickener and is fortified with extreme-pressure, anti-oxidant, anti-wear and anti-rust additives.

  • Fully biodegradable to the latest CEC-L-33-A-93 standard
  • Provides resistance to the formation of deposits caused by oxidation at high operating temperatures and maintains consistency, thereby reducing leakage
  • Offers good corrosion resistance characteristics to offer effective protection in challenging environments.

Approvals from leading marine manufacturers include*

  • Becker Marine Systems (full approval for rudder carriers)
  • Rolls-Royce (full approval for rudder carriers)

*The information and guidance offered for use of Shell Naturelle products is based on experience and understanding gained through the development and manufacturing of lubricants. The performance of the products can be influenced by a number of variables, not limited to, contamination, operating temperature, equipment application, external environment and material type.

The suitability of Shell Naturelle products must be checked for all applications with original equipment manufacturers (OEM) or with Shell technical representatives before these products are used. It is important to check that the fluid has the necessary OEM approval for the specific make and model of equipment and to check that the materials used for seals, flexible hoses, O-rings and tank coatings are also compatible with the Shell Naturelle products that are to be used.

Please contact your Shell technical manager for the complete list of approvals.
