Small volume crankshaft
We have the equipment to meet all kinds of customer needs,
and we can handle large crankshafts (up to 4 meters).
The highest technology for all types of crankshafts
We provide the highest quality crankshafts with the highest technology that we have developed for
all kinds of crankshafts from automobiles, outboards , construction machinery, agricultural machine,
and light aircraft of famous Japanese manufacturers.
As long as you provide us with the machining drawing, you can order from one crankshaft to the finished product.

We can also handle small-lot production from a single unit.
No matter how small the quantity, we can handle the prototypes that are requiredin the development field, where trial and error is constantly being conducted fornew projects, or the production of test pieces for the launch of a new productionline.
- Prototype(forged , round bars )
- Service parts
- Small spots
- Blank processed
- Development project
- Test piece processing for line start-up

It can be machined from a round bar.
For example, if there is a sudden need for a replacement part, but the forging diehas already been scrapped and cannot be rebuilt, we can cut it from the round barand process it to the final product. We can also handle small quantities and shortdelivery times.
- Service parts
- After parts

Capable of machining axes up to 4,000 mm in length.
Yuasa has equipment capable of machining up to 4,000mm, and can process anyshaft shape. The longer the length, the higher the accuracy required, and we canachieve this with our extensive know-how.
