Is it bad practice to use assembly lube or grease on say, tapered roller bearings when they'll be operating with a much lower viscosity fluid during service?
@averyalexander23037 ай бұрын
Great question. A thick ish oil certainly wouldn't be bad since oil gets very thick in extreme cold anyways and that doesn't cause damage, but I could see how grease may be bad although I'm no expert. Whenever I've replaced bearings in transmissions and such (which hasn't been very many times), I've always just lubed them with whatever oil they normally use because they were going right back into service. As long as the machine will be put into service reasonably soon, there's nothing wrong with just using their normal oil as an assembly lube.

One factor with rolling element bearings that I have not been able to understand well is how an increase in grease viscosity will increase rolling resistance, but this resistance increases heat generation and temperature, decreasing viscosity and friction. The calculators I have used make this calculation an iterative process and it is hard to grasp the relative changes of each variable. Do you have any suggestions?

There was something published a few years ago that may help you expand on this. Just do a search for "Prediction of the Stribeck curve under full-film Elastohydrodynamic Lubrication". It's an expansion of Stribecks work on the journal bearings.

HI.CAN YOU MAKE A VIDEO ON THE SIGNIFICANCE OF ALKALIZED NAPHTHALENES IN OIL..FOR EXAMPLE LIKE 10-20% ADDITIONAL I WOULD LIKE TO KNOW MORE ABOUT THAT BECAUSE I THINK IT IS THE FUTURE OF MOTOR OILS
