Determination of Static Friction
MCR tribometers from Anton Paar enable precise and
reproducible measurements of tribological characteristics
such as limiting friction and break-away forces.

Accurately determine the static friction for material selection and
process optimization with an MCR tribometer
Static friction is the frictional resistance to motion by the system at rest. The
value of the coefficient of friction just before the onset of motion is the limiting friction and the corresponding force responsible for setting the system
in relative motion is the break-away force.
These values are essential in various applications such as gears, bearings,
brakes, sliding glides, fishing equipment, conveyor systems, locks, etc.
Good to know
An MCR tribometer provides quick, accurate, and highly reproducible static
friction measurements with a range of
different contact geometries.

• CTD 180, CTD 620
Precision and reproducibility - Measurements with MCR tribometers
Determination of limiting friction requires highly precise force and motion
control. MCR tribometers offer precision at the micro- to nanoscale along
with high reproducibility. You can evaluate subtle differences in the static
friction behavior of tribological systems and improve their efficiency with
the help of an MCR tribometer.
You can choose between oscillation or rotation modes of testing to determine the limiting friction or break-away forces.
You benefit from superior environmental control with temperature ranges
from -130 °C to 620 °C and humidity control between 5 % and 95 % relative humidity.

A motion control covering 9 decades in speed and deflection allows measurements of Stribeck curves revealing static friction and film formation
properties in one measurement.
