Strengths of Sanwa Seiki

We boast high expertise and market share in pneumatic and hydraulic technologies.

In pneumatics, we possess technology capable of handling both positive and negative pressure, with additional strengths in fluid control.
In hydraulics, we have established an in-house system capable of handling everything from hydraulic circuit calculation and analysis to prototyping and evaluation.

We have built a solid track record and trust in the commercial vehicle sector.

Furthermore, our reach extends beyond automotive components,
expanding into diverse industrial sectors such as construction machinery, agricultural machinery, and industrial equipment.
Leveraging our strengths in functionality and durability that withstand harsh operating environments,
we provide essential support behind the scenes for social infrastructure and industrial activities.

Since its founding in 1938, Sanwa Seiki has remained steadfast in its commitment to creating products that truly serve the needs of the field.
Our manufacturing philosophy is rooted in a “Hands-on approach”—designing and refining products based on deep understanding of their usage environments—and an engineer-driven “development system.”

At each development gate, we hold meetings involving field personnel to incorporate their actual feedback into prototypes and specifications.
The product lineup born from this iterative dialogue embodies insights and convictions backed by history.

Furthermore, we focus on passing down technical expertise through On Job Training and daily operations, ensuring accumulated knowledge is passed on to the next generation.
