lubrication

Harrison designed this clock, like most of his clocks, to run without lubrication, eliminating another source of variability.

Also, lubrication is provided by oil mixed in with the fuel rather than a closed-loop oiling system.

This shaft is, traditionally, only a few inches long, and has some pretty sophisticated lubrication systems.

This also reminds me of the quote from Heinlein: Moving parts in rubbing contact require lubrication to avoid excessive wear.

Teletype machines, which do roughly the same job, are much louder and need considerable lubrication.

This offers the most lubrication, which will protect your face from the sharp blade.

Grease provides lubrication to prevent pressure welding of the bearing to the race and it can also act as a heat sink.

The bigger problem (other than lubrication) is managing the moment of detonation.

Perhaps this geometry is easier to handle wrt seals and lubrication.

Daily lubrication of the chain prevents it from becoming dirty, and a chainguard (or even better, a chaincase) prevents most things from touching it anyway.

This keeps the noise down and reduces the need for lubrication.

Honorifics and formal politeness provide lubrication where people rub together.

If it's doing that out of the box, then the "improper lubrication" is a defect of the keyboard.

Reminds me of a quote from Robert Heinlein "Moving parts in rubbing contact require lubrication to avoid excessive wear.

Also: "Because so many potential applications are in the lawn care and landscaping biz, the current design runs on a mix of gasoline and oil for lubrication." I doubt they'll be able to meet emission standards, which is another reason you'll never hear from them again.

For example: Bike Chain Installation + Bike Chain Lubrication.
