Store Standards catalogue ICS 75 English French. ILS ISO Synthetic multi-purpose lubricating grease is manufactured using synthetic hydrocarbon base oils and a special lithium complex soap thickener ideal for providing high temperature stability during heavy-duty operations.

This line of lubricating greases contains superior components including high quality anti-corrosion inhibitors to protect yellow and ferrous metals, among other gears and rolling element bearings under moderate to extremely high load.

All ILS Synthetic Lubricating Greases are based on fully synthetic hydrocarbon, beige in color, homogeneous in texture, and can guarantee lifetime lubrication to rolling element bearings in modern industrial food manufacturing plants.

Prove you're human by entering the code below. Using a pattern that conforms to uncertainties imposed by dimensional manufacturing tolerances. The reference temperature for the classification should be reasonably close to average industrial service experience. It should also relate closely to other selected temperatures used to define properties such as viscosity index VI , which can aid in defining a lubricant. For the classification to be used directly in engineering design calculations in which the kinematic viscosity of the lubricant is only one of the parameters, it was necessary that the viscosity grade width range of tolerance be no more than 10 percent on either side of the nominal value.

This would reflect an order of center point uncertainty in calculations similar to that imposed by dimensional manufacturing tolerances. This limitation, coupled with the requirement that the number of viscosity grades should not be too large, led to the adoption of a system with gaps between the viscosity grades. For petroleum-based liquids, this covers approximately the range from kerosene to cylinder oils.

The 20 viscosity grades with the limits appropriate to each are listed in Table 1. The classification is based on the principle that the midpoint nominal kinematic viscosity of each grade should be approximately 50 percent greater than that of the preceding one. The division of each decade into six equal logarithmic steps provides such a system and permits a uniform progression from decade to decade.

The logarithmic series has been rounded off for the sake of simplicity. Even so, the maximum deviation for the midpoint viscosities from the logarithmic series is 2. Table 2 pulls together some popular viscosity measurement methods into one table. If the practitioner is comfortable with one particular measure but would like to see the correlating viscosity range in another measure, all he must to do is place a straight horizontal line through his chosen viscosity type and see its correlation within the other types of measures.

While it is true that some viscosity grades will be left out of the mix as companies move toward adopting the ISO designation, it is not necessary that the users of those products have to move away from them. Further, there is no intention to offer quality definition of lubricants with this scale.

That a product has an ISO VG number associated with it has no bearing on its performance characteristics. The ISO designation has been under development since The most recent release in ISO contains 20 gradients. This covers nearly every type of application that the lubricant practitioner can expect to encounter.

Yes, viscosity of the base oil is an important property and is not addressed in the NLGI grade. The viscosity of the base oil is not a secret, it is available from the manufacturer and should be considered along with other paramters in grease selection.

For the Mobilith SHC series discussed in the other thread, the viscosity of the base oil is part of the grease identification.

According to most sources, the minimum base oil viscosity at operating temperature in grease for greased bearing is the same as minimum oil viscosity at operating temperature for oil in oil-lub'd bearing Excessivly high viscosity far above the minimum causes unnecessary heating. Also a lot of people say pressure viscosity coefficient of the base oil is important.

For non-synthetic oils there is not much variation in this parameter, but for synth oils there is wide variation.
