|
Reichert TesterThis Reichert test method covers the procedure for determining wear properties (WP) and extreme pressure properties (EP) to evaluate lubricant and additives. |
K94190 |
|
ATF Ball on Cylinder Lubricity (BOCLE) Test RigThe ATF BOCLE Test Rig covers the assessment of the wear aspects of the boundary lubrication properties of aviation turbine fuels on rubbing steel surfaces. |
K93500

|
Pin on Disc TesterThe Pin on Disc Tester is primarily intended for determining the tribological characteristics of a wide range of materials under various conditions of normal loads and temperatures. The Data Acquisition System incorporates sensor and signals with a combination of data acquisition hardware and software to create a complete measurement system. |
K93700 |
|
Air Jet Erosion TesterThe Air Jet Erosion Test Rig has been developed to evaluate the erosion resistance of variety of materials and conforms to the specifications of ASTM G76 standard. The principle of operation consists of subjecting the test sample to a jet of air carrying the erodent, through a tungsten carbide nozzle of a known diameter. |
K93495 |
|
High Frequency Reciprocating Rig (HFRR)The High Frequency Reciprocating Rig is a versatile computer controlled apparatus for evaluation of the coefficient of friction and wear properties of materials under dry and lubricated conditions. |
K93300 |
|
Dry Abrasion TesterThe Dry Abrasion Tester uses a rubber-rimmed wheel as the bed for silica abrasive that is fed from a hopper by a nozzle between the sample and the wheel. The sample is pressed into the wheel by a dead weight loaded lever. The test is run for a set number of revolutions with automatic cutoff and the wear is measured by measuring the volume of material lost through mass loss and density measurements. |
K93800 |
|
High Temperature Grease Life TesterThe High Temperature Grease Life Tester evaluates the performance of lubricating greases in ball bearings operating under light loads at high speeds and elevated temperatures. |
K95190 |
|
Pin and Vee Block TesterThe Pin and Vee Block Tester consists of a rotating pin pressed between two stationary steel Vee blocks. Load is applied to the Vee blocks by a ratchet mechanism. Ramping of load during extreme pressure testing is made possible by auto-advancement mechanism of ratchet. Pin and Vee blocks are immersed in lubricant fluid under test conditions in heated test cup. |
K92800 |
|
Slurry Abrasion TesterThe Slurry Abrasion Tester is designed such that a standard specimen is pressed against a rubber wheel with a known force. The test area is submerged in wet abrasive slurry. The wheel carries grip particles across the contact face in the direction of wheel rotation. |
K93692
|
|
Thrust Washer TesterThe Thrust Washer Tester is used to determine the equilibrium rate of wear and coefficient of friction of materials in rubbing contact under combinations of pressure and velocity that utilizes a thrust washer specimen configuration as per ASTM D3702. |
K94300 |
|
Grease Noise TesterThe Grease Noise Tester evaluates the lubrication integrity of greases, providing a quantitative assessment of the noise characteristics of the grease. The use of clean lubricants is essential for obtaining long bearing life. Many factors affect the degree of cleanliness of greases during normal operation. |
K94800
