Coefficient of Friction
Test show that NanoSlick Lubricants are able to achieve an amazing 0.078 Static Coefficient of Friction for Steel on Steel.
The table below shows an average static Coeffcient of Friction for most material on material, with and without lubrication. It is clear that our lubricants can provide one of the most lubricious surfaces which means less friction, less wear, less heat, and less loss of energy and performance! Usually this is only achieved through a very expensive process of coating with a dry lubricant, we achieve this amazingly low Coefficient of Friction with our flagship grease lubricants! NanoSlick Slick-33 is our low coefficient of friction grease ever produced!
The frictional force for Static Friction can be expressed as:
Fmax= μ Fn
where
Fmax= Frictional force (N, lb)
μ = static (μ s ) or kinetic (μ k ) frictional coefficient
Fn = Applied Normal force (N, lb)
The frictional force for Dynamic Friction can be expressed as:
For an object pulled or pushed horizontally, the normal force - N - is simply the weight :
N = m g
Where:
m = Mass (kg, slugs )
g = Gravity (9.81 m/s2 , 32 ft/s2)
