PTFE Slide Bearings & Calculating it's Coefficient of ....

PTFE Slide Bearings: Calculating Coefficient of Friction. PTFE is a preferred material in slide bearings for three very specific reasons:Load bearing capacity, Weather ability & Low coefficient of friction. We calculate the PTFE Coefficient of friction by processing gauging the angle of incline.

Compounds and Semi-Finished Products Made from PTFE: Properties and Applications Modified PTFE Derived from standard PTFE, a new product – modified PTFE – is created by co-polymerization with a small quantity of a perfluorinated modifier and reduction of the molecular weight. Although modified PTFE can be processed by the same meth-

To fulfill the special demands of the new test-setup, greased, only 0.5 mm thin sheets of PTFE were used to minimize friction between the bearing construction and the test specimen. This highly effective sliding construction leads to a dynamic friction coefficient μd,max between 0.0065 and 0.0035 while the static friction coefficient μs ...

cart? If the coefficient of friction is at all reasonable, such as when μ = 0.05-0.1 for greased sliding contact bearings, and if D/d is on the order of 20, the force is 200-400 times less than the weig ht of the cart. Hence one can see why for a long period in human history that sliding contact bearings were perfectly adequate.

The primary factors affecting the friction of GGB-DB® bearings are pressure, velocity, temperature and mating surface condition, with pressure being the most influential. Coefficient of friction and wear rates are subject to many factors. Under high loads and some humidity, for example, the value could be as low as 0.06; under lower loads and high
