The phrase "a lubrication" is correct and usable in written English.
It can be used when referring to a substance that reduces friction between surfaces, often in mechanical or technical contexts.
Example: "Before assembling the parts, make sure to apply a lubrication to ensure smooth operation."
Alternatives: "a lubricant" or "a grease".
Officials suspect that because the wheels were operated at low speed for a long time, there may have been a lubrication problem.
The watchmakers use gold chatons with steel screws to hold down the rubies that act as a lubrication system for the watch.
Several nuclear power plants, for example, were recently able to find a defective part meant for a lubrication system while it was still in their warehouses, after one plant had to shut down because of a failure, and another of similar design shut down as a precaution and found the part that it was using was defective, too.
Results are compared with a lubrication theory for spreading droplets.
One system is a lubrication supply system and the other is a liquid seal supply system.
The correction is imposed through the addition of a lubrication barrier force on affected particles.
This little egg-shaped rubber goo-ball of fun reminds me of the "Super-Suzy," which is the version of Suzy made with a toilet paper roll stripped of the cardboard tube and a lubrication-soaked latex glove covering the hole so when you fuck the hole, the TP roll stretches out and molds to your Johnson.
A decreasing friction factor with increasing Sommerfeld number indicates a mixed lubrication regime, a rising friction factor with increasing Sommerfeld number indicates full-fluid film lubrication, and boundary lubrication is shown as a flat trendline with no dependence of friction factor on Sommerfeld number (Unsworth 1978, Dowson 2001).
The viscosity of the lubricant is a very important property in choosing a lubricant for hydrodynamic lubrication.
A mixed lubrication model of a rotary lip seal using flow factors has been developed.
The explanted joints tested operated in a mixed/boundary lubrication regime with a decreasing friction factor observed with increasing Sommerfeld number.
