It is classified according to a scale developed by the NLGI (National Lubricating Grease Institute). The softer the grease, the lower the number. Grease for bearings are typically NLGI 1, 2 or 3. The test measures how deep a cone falls into a grease sample in tenths of mm.

What grease is safe for electronics?

Silicone grease
Silicone grease can be used on all your electrical connections and on battery terminals. They are widely used on spark plug cable rubber boots as well as a sealant for spark plug threads. They also help prevent electrical failures caused by moisture and corrosion.

How is lubricating grease rated?

It is classified according to a scale developed by the NLGI (National Lubricating Grease Institute). The softer the grease, the lower the number. Grease for bearings are typically NLGI 1, 2 or 3. The test measures how deep a cone falls into a grease sample in tenths of mm.

What is PTFE grease used for?

White-coloured grease with PTFE specially formulated for use on most mechanisms: sliding guides, chains, open gears, plain bearings…, used in industry and in particular in the food sector. The presence of PTFE ensures the formation of a dry film. It reduces friction and avoids fouling by solid contaminants.

What grease is non conductive?

Dielectric Grease
What Is Dielectric Grease? Dielectric, sometimes referred to as tune-up grease, is a viscous non-conductive waterproof substance used to protect electrical connections from corrosion and dirt.

What is NLGI rating on grease?

The NLGI number is a measure of the grease’s consistency as indicated by its worked penetration value. The penetration test measures how deep a standard cone falls into a grease sample in the tenths of millimeters. Each NLGI grade corresponds to a specific worked penetration value range.

What are the disadvantages of PTFE?

Depending on the application, the following disadvantages can rule out the selection of PTFE:

• Price – it is not a low-cost polymer.
• Production sizes – it is not easy to mass produce.
• It cannot be cemented.
• It can change shape under pressure.
• It is unweldable.

How do I choose a lubricant?

To determine which type of lubricant is best for an application, one must understand the current situation. Look at application/environmental factors such as speed, temperature, load, vibration, moisture, and dust. Consider that: Temperature determines lubricant base oil type.
