In cold weather conditions you need a lubricant that can perform and will not let you down. NanoSlick™ Arctic Shield is specifically for extremely cold conditions with Tungsten having a temperature resistance of -45°F to 450°F (-43°C to 232°C), and is based on advanced technology that improves lubrication properties by decreasing friction and wear, thereby extending gear life. NanoSlick™ Arctic Shield consists of a state-of-the-art premium plus, water-resistant grease infused with 99.9% pure Tungsten Disulfide (0.6 micron), our own special blend of rust and corrosion inhibitors, making NanoSlick™ Arctic Shield the slickest, highest quality professional lubricant for cold conditions!

Often the focus is only on the upper limit, since high temperatures can wreak havoc on the health of the lubricant and the machine, as well as cause safety concerns in some cases. However, rarely do you hear someone discussing the lower limits.
At extremely low temperatures, such as those experienced during the startup of equipment found outside on a cold winter morning, the fluid within the housing can reach a point where it actually congeals and will no longer flow. This limit is called the pour point.
In circulating systems, the viscosity becomes so high at this point that the oil flow is restricted. Components will then starve of lubrication, which leads to an early metal-on-metal death.
Of course, circulating systems aren’t the only ones that rely on oil flow. Imagine how a splash-lubricated gearbox handles a cool, thick fluid. When these gearboxes are designed properly and using the correct fluid viscosity, oil is brought up to the gear tooth interface and even to the shaft bearings and other reduction stages higher in the sump as the gearset runs through the oil sump level.
When the oil viscosity is increased to the point where it will no longer flow, the submerged gear will push congealed “chunks” of lubricant out of the way and will not lift it to the other components within the housing that desperately need to be lubricated. Another side effect of the increased viscosity is a higher startup torque. This increased load may be enough to cause a catastrophic failure or at least consume a massive amount of energy because of the excessive friction.
Understanding what happens to your lubricants at cold temperatures is your first line of defense. So the next time you walk into your plant on a cold morning and prepare to start up the equipment, please think about the consequences of the cold temperatures on your lubricants and the machinery.
Grease, in its simplest form, is base oil emulsified with a thickening agent to create a semi-solid, which serves as a carrier for the base oil and any additives that have been included. For polar extremes, PAO base oils are a mainstay for grease composition (for the reasons outlined above). As for thickeners, aluminum complex is a front-runner among other options, including soaps, calcium and lithium. Aluminum complex provides a high level of overall protection, including excellent water, rust and corrosion resistance, high load-carrying abilities, excellent temperature range variation and pumpability in cold conditions.
It’s also “reversible” and will revert to its normal consistency after having been heated and cooled repeatedly. This makes it ideal for the large temperature ranges of cold extremes. Additives also play an important role. There’s a broad spectrum of additive combinations, which enhance extreme cold performance. Fully formulated grease with a balance of base oil, thickener and additive package will offer definite performance advantages including:
- Excellent water emulsification
- Heavy-duty load, anti-wear and extreme-pressure protection
- Tackifiers for extra adhesion
- Resistance to salt and fresh water, chemicals and other contaminants
- Compatibility with metals and mineral/synthetic oils
- Clean and free of heavy waxes
- Low start-up torque and smooth operation
