Rotary | Linear | Block on ring | traction Ducom Pin on Disk Tribometer - POD 4.0


The tabletop POD-4.0 is a high performance, multi capability  tribometer that is capable of performing various popular tribology tests in a single instrument. The system is capable of conducting pin on disk tests, linear reciprocating tests, block on ring tests (work in progress), traction tests (work in progress) and many others.

An ecosystem of environment and sensing modules is available for everything from lubrication and tribocorrosion studies to humidity control and high temperature testing.

It is modular, powerful and deeply automated making it simple to use.

Transforms effortlessly

quickly change modules to match your needs

Using its fast interchange mechanism, the POD-4.0 can easily transform itself and unlock new testing capabilities. You can start simple, with a base POD-4.0 tester and keep adding on modules to address your testing needs. Motion modules for angular reciprocating, linear reciprocation and block-on-ring tests are available. Various sensing, environment and other options are also available. Its modularity allows upgradation at any time after the purchase.

High Speed Tests

The test specimen disk mounted on an inline spindle assembly is driven directly by the servo motor without any belt or gear assembly. The spindle speed can be controlled up to a maximum speed of 3000 rpm. 


  • Control the spindle acceleration and deceleration at high speed
  • Control the decay rate of spindle speed for Stribeck like curves

Ultra Low Speed Tests

The test specimen disk mounted on an inline spindle assembly is driven directly by the servo motor without any belt or gear assembly to control the speed as low as 0.1 rpm. The rotary encoders along with control feed back loop system ensure accurate control of set low speed.

change can be hard. pod 4.0 makes it easy 

Easily interchangeable set-up allows the POD 4.0 to transform from a rotary tribometer to a linear reciprocating tribometer in under 2 minutes. Movement options and precise motion control are available for various movement types. High precision rotary motion capability for clockwise and counter-clockwise movements comes standard with the POD-4.0 (speeds from 0.1 rpm up to 5000 rpm). This capability can be expanded by adding angular oscillation module, linear reciprocation module, block on ring module and other motion modules.

Pin on Disk Tribometer - POD 4.0


Every POD-4.0 includes a high resolution wear measurement sensor. The measurement system is designed to eliminate thermal drift when used with high temperature modules. Its wide range and good sensitivity make it excellent for testing everything from testing thin coatings to soft materials. 

interchangable loading system 


The POD-4.0 comes standard with a dead weight loading system that can be used for low load testing down to 0.25 N all the way up to 200 N, without needing to change any parts.

The loading system can be upgraded to a fully automatic loading system in just minutes, enabling advanced functionalities across the entire loading range. The automatic loading system is ideal for applications where a programmed run-in, ramp or step loads are required.

Automatic Scar Prediction


Every HFRR test is concluded by measuring the wear scar on the test specimens. This has so far been the most manual aspect of the HFRR testing and prone to user errors and interpretation. The difficulty in visual observation of scars with ultra-low wear further increases the test variability. With our proprietary automatic scar prediction software, you can now harness the power of Artificial Intelligence (A.I.) to automatically make consistent and precise wear scar measurements, overcoming the human error and greatly reducing the test variability.
