Applications:

The OT-2000 Multifunctional Friction and Wear Tester is a universal tribometer. Designed by our company on the basis of many years of industry experience in tribology and incorporating the advice of professors and experts from several universities, this multifunctional friction and wear tester adopts a modular design that enables the analysis of material wear, friction and mechanical properties on a single platform. It is applicable to tribological characterization in the fields of lubricants, lubricating oils (greases), biology, automotive, semiconductors, aerospace, materials, ceramics, etc. In order to obtain useful tribological data, it is important to carry out tests under conditions close to those of actual applications. The multifunctional friction and wear tester offers a variety of motion modes, a wide loading force range, and a selection of environmental chambers and specimen fixtures. The machine is computer control with strong function of software for friction and wear test.

Equipment Description

1. Z-axis drive system: high-precision multi-stage Z-axis with a maximum travel of 280 mm, enabling high-precision and multifunctional loading modes and detection;

2. Open platform: an open platform design is adopted; with the Z-axis drive integrated, the working area becomes considerably wider;

3. Replaceable test modules at the lower part: multiple tests (rotation, reciprocation, block-on-ring, fretting, scratch, etc.) can be performed on the same platform, allowing quick module changeover;

4. Environmental control: temperature (from room temperature to 500 °C);

5. XY bidirectional multifunctional platform: travel 130 × 130 mm (±80 × ±80 mm), enabling specimen movement during friction testing and used for automatic specimen positioning and position setting. It can be used for medium- and low-speed linear reciprocating tests, scratch tests, etc.;

6. Data acquisition and control: high-speed, low-noise, fast-response controller; data sampling rate up to 100 kHz;

7. Force sensor: 10 N–1000 N, using high-precision, wide-range interchangeable force sensors;

8. The software has strong function to do lots of friction and wear test.

Module Description (modules can be customized and added) 

1. Reciprocating module As ASTM G133

The upper specimen — usually a ball, pin or cylinder — is pressed against an oscillating plate. The friction coefficient, friction force, wear rate, wear volume, temperature and other tribological properties can be measured. The ball/pin-on-disc friction and wear tester can characterize the tribological properties of alloys, ceramics, polymers, metals, coatings and solid lubricants. The linear reciprocating module can operate at high frequencies, over a wide load range and in various environments.

2. Pin (ball)-on-disc friction (rotation) as ASTM G99

The friction and wear testing machine presses a stationary pin or ball against a rotating disc, and can measure the friction coefficient, friction force, wear rate, wear volume, temperature and several other tribological parameters. It is an ideal choice for characterizing the tribological properties of alloys, ceramics, polymers, metals, coatings and solid lubricants.

3. Block-on-ring friction as ASTM G77

The block-on-ring friction tester generates wear through friction between the ring and the block. During the test, the specimen ring is placed on the driving device, which rotates the ring and generates friction against the surface of the block material fixed in the same plane. It is mainly used for the lubricating performance test of various lubricating oils and greases; it can also be used to evaluate the wear performance of metallic and non-metallic materials.

4.  Extendable: tapping torque test, sealing ring, thrust ring, etc. (Optional)

5. Extendable: 3D modeling height measurement with extended-depth-of-field microscope (Optional)
