Testing and evaluation
We propose optimal specifications by completing design investigations in the upstream section of the V process.
Analyses and simulations, which are upstream processes in the V process, and unit testing and evaluations of actual machines, which are downstream processes, are all performed in-house. Directing feedback of evaluation results into the analytical technology makes it possible to improve the strength and precision of model-based development (MBD). Accordingly, we can propose highly accurate and optimal materials from the initial stages of development and thereby help clients speed up the development process and reduce man-hour requirements.
Accommodating client needs with an extensive array of technological solutions covering everything from basic research on to the manufacturing of engine parts
For our slide bearings, our flagship product, we must ensure excellent slide and lubrication performance and exceptional durability and wear resistance in extreme sliding environments. For this reason, we observe and measure the coefficient of friction, lubrication performance, and wear performance under conditions that replicate actual usage conditions as much as possible through stand-alone and actual equipment testing and work to harness the results of this process to develop and manufacture high-performance bearings.

Clarifying the bearing seizure mechanism with AE measurements
By positioning AE sensors in a bearing and taking measurements with the use of a bearing testing machine, we can ascertain the process by which bearing materials become damaged in real time. This can reveal the mechanism by which seizures occur and is used for designing materials.

NClarifying the relationship between NV measurements and axial center behavior
By taking NV measurements after attaching an acceleration sensor to an engine in an actual engine test and checking the results against the behavior of the axial center trajectory in the bearing, a correlation can be obtained. This can be used to design bearings with low NV by suppressing the axial center behavior.
