Lubricant Performance Tests

Analysis

We evaluate the performance of lubricants and determine their compatibility with other materials. Upon request we can also conduct various machine-rig tests, using precise simulations of real-world operating conditions. Please contact us for further details.

Featured Activities

* Compatibility with other oils and materials (blending stability, rubber swelling, etc.)

* Various oxidation tests (ISOT, RBOT, TOST, etc.)

* Lubrication property, extreme-pressure performance (Shell four-ball, SAE No.2, LVFA, SRV, etc.)

* Low-temperature fluidity (CCS, Brookfield viscosity, etc.)

SAE No.2 clutch friction apparatus
SAE No.2 clutch friction apparatus

The exam evaluates the friction characteristics between a clutch (friction material) and lubricating oil based on the JASO method for automatic transmission fluids (JASO M348:2002). Dynamic friction test and static friction one can be combined and uninhabited operation by the program is possible.

LVFA (Low velocity friction apparatus)
LVFA (Low velocity friction apparatus)

An exam evaluates the durability of the "stick-slip" control in a single clutch based on the anti-shudder performance of automatic transmission fluids (JASO M349:2001).

(Shudder: self-excited vibration generated in a friction clutch and a friction brake).
