CETR offers a wide range of solutions to meet your lubricant and oil research and analysis needs. Our fully-computerized testers of the unique acclaimed design can perform practically all common tribological tests , which has made them the most widely used tribological testers in the world.
In all these and numerous tests, the tool can perform an automated synchronized control of several
specimen motions with linear speeds from 0.1 micron/s to 30 m/s (7 orders of magnitude!) and
angular speeds ranging from 0.001 to 7,000 rpm, under the precision loads from 1 N to 1200 N (9
orders of magnitude!). In these unprecedented wide ranges, the UMT can automatically monitor a
number of process parameters in-situ with a high sampling rate
The tool comes with the optional add on environmental chambers that can go from -40 to 1000 degree C, under vacuum or under humidity or gases.

Typical tests run on the UMT-3 tester include:
- Pin/ball-on-disc with an either reciprocating (spiral wear track) or rotating (crater-like wear
track) or stationary (circular wear track) upper pin or ball (from 1 to 25 mm) on an either rotating
or stationary disc (up to 150 mm),
- Disc/ring-on-ring/disc with both or one of the disc/ring rotating,
- Pin/ball-on-plate with an either reciprocating or rotating or stationary upper pin/ball (from 1 to
25 mm) on an either linearly-reciprocating or stationary plate (up to 150 mm),
- Flat-on-flat with self-aligning specimen holders and at least one of them linearly-reciprocating;
when both of them are linearly reciprocating in perpendicular axes, a controlled ratio of their
frequencies allows for either circular (ratio of 1) or butterfly-wings (ratio of 2) or other
programmable wear track patterns
- Block-on-ring/wheel with a rotating ring/wheel/bearing/seal (including standard Timken and
Falex rings) and either stationary or sliding block or plate:
- Cylinder-on-cylinder, with either one or both of them rotating and one of them sliding on the
other at the programmable angle from 0 (parallel axes) to 90 degree (perpendicular axes),
- Screw-in-nut or drill-in-hole, with either screw/drill or nut/hole rotating and either the same or
other specimen moving in and out of the thread/hole.
- Numerous tests of fuels, oils, greases and solid lubricants:
- Variable rolling to sliding test
- Butterfly stroke test
- Gear testing
