Tribology
Studies / Wear Testing
Pin-on-Disk Testing
Our Pin-on-Disk apparatus conforms to ASTM G99-95a for measurement
of wear and includes kinetic friction measurements. Measurements
can be done with or without lubrication. Variables besides load,
speed and temperature include wear specimen composition and
geometry (pin and/or disk). Coefficient of friction and wear
scar severity allow the direct comparison of one lubricant to
another. |

Fretting Corrosion / Fretting Wear
Testing
Fretting corrosion or fretting wear of surfaces in vibratory
contact can be measured using this unique test apparatus. Comparison
of a lubricant's (grease or oil) fretting resistance performance
can be quantified quickly and economically. Our experience shows
that less than 30 seconds is required to generate a fretting
corrosion site on a cleaned steel friction pair that could be
mistaken for a rust! |

Hydrodynamic Oil Film Failure
A low-voltage electrical circuit is used to detect oil film
failures in journal bearings due to high loads or temperatures.
This unique arrangement can simulate the operation of tilted
pad bearings, such as are found in hydroelectric turbines, coolant
pumps and thrust bearings. |
 |
Rolling Element Bearing Torque Tester
The rolling element bearing torque tester is unique and measures
bearing rolling torque. It allows for the direct comparison
of bearings or lubricants used in bearings. Maximum bearing
size is 100 mm (4 in) OD. |
 |
Pad-on-Disk Testing
Friction and wear of Pad-on-Disk simulates situations found
in low-speed heavily-loaded trunnions or journals in dams or
bridges. Static (break-away) friction and low-speed (i.e. 0.2
in/min) kinetic friction are measured. The apparatus is used
to optimize grease and material combinations. |
