2. Loco2's knowledge base. Hereâs a look at one of our friends, Loco2, a service where you can book train tickets like plane tickets. Loco2 is a straightforward service, so it makes sense why their front page showcases the two most important inquiries: booking and traveling.
Lubrication is the process, or technique employed to reduce wear of one or both surfaces in close proximity, and moving relative to each other, by interposing a substance called Lubricants between the surfaces to carry or to help carry the load between the opposing surfaces.
A good lubricant is cohesive so that it will exhibit good capillary action that will keep it in its place. A thicker lubricant has larger molecules (a longer carbon chain in the case of petroleum-based lubricants) and therefore provides a thicker film that keeps the metals further apart and resists higher pressures.f less friction takes place in the 2nd wheel bushings, you would expect less wear. This suggests that the increase in wear takes place not because of friction but because of something else: the yield pressure of the metal is exceeded, causing premature failure which we see as small pits in the pivot.
