Chain lube, food for thought.

<< < (6/6)

K2-K6:
To offer a more quantitative view,  I looked after, for a a time, some industrial process machinery that wasn't chain driven.

The configuration had direct drive electric motor driving long chain that ran process line, for which timing was critical.
They were checked for each daily production cycle at specified time,  adjusted (if needed)  by analog speed control,  had an ammeter in supply to monitor motor power consumption (and hence driveline friction), along with motor temperature logging to ensure it didn't breach critical heat in service which would result in safety shut down.

The chain on these is the greatest variable in its efficiency,  making sure that was kept in the best condition key to reliable running which was generally about 12hrs per day over six days.

The best performing lubricant was sticky propellant applied chain lube with molybdenum disulphide content,  by such a significant margin that it made absolutely no sense not to use it.
General oil,  EP oils, etc would offer close to the same levels of friction WHEN they we're applied, with the resulting amps driving and set point of the speed control indicators confirming this. That data was recorded on startup records as part of running them.
But for pure long service interval operation they had no match for the chain lube.

It gave me a convincing view of the potential of each choice,  which I feel is relevant to bikes.

The original assertion in the video was that chainlube was a rip off.  It doesn't follow in logic there either, the chainlube almost totally removed wear on these machines,  taking maintenance downtime and component cost virtually out of the equation in operating them.

That's what MDS  is good for,  also why it's used in high pressure low movement metal to metal interfaces which ultimately prevents spalling and associated wear.
