Crankshaft Machinig / Long Shaft Machining
Global crankshaft / long shaft solutions to answer all your needs,
from anywhere in the world.
One of the best domestic technical skills and know-how that we have learned of micron order
It is one of the few independent companies in Japan that has the equipment and technology to carry out integrated production of mass-produced products and high-mix low-volume crankshafts from material to completion.
The crankshafts we manufacture are used in a wide range of industries, including automobiles, motorcycles, outboard motors, light airplanes, agricultural machinery, and industrial machinery.
With the technology and expertise cultivated in this diverse achievement, I gained confidence that I canrespond accurately to every shaft needs.
Please use Micron quality realized by Yuasa for your products.
From the backup of the medium-term crankshaft production system to short-term response, As a strategicpartner to support the development of our customers, we will play a part in suppliers that realize highquality products.
We can also process long shafts used in various industries with the technology we have cultivated over the years in crankshafts.
We can handle the entire process from material arrangement to completion and delivery, including heat treatment and surface treatment.
