Policy

Of all our products, hydraulic devices and gearboxes for construction equipment are by far subject to the greatest demand. Koretsune Seiko also produces hydraulic cylinders for power steering systems of tractors, combines, and other agricultural machinery; gearboxes and other products utilizing hydraulic systems; and cylinders used in passenger boarding bridges at airports. Koretsune Seiko brand products are used in a diverse range of industrial machinery, as well. Our objective is to constantly meet the challenge of researching, developing, designing, and manufacturing new products you won't find anywhere except at Koretsune Seiko.

Hydraulic cylinder

油圧シリンダー

Hydraulic cylinders used in construction equipment use high-pressure (35 MPa) hydraulics under extreme working conditions, and in order to prevent leaks and other problems, seal housings and other precision parts must be machined to micron-level tolerances. To ensure the strength of our products, we use high-tension steel as well as other new materials and technologies needed to fulfill our customers' requirements. That's the stuff that Koretsune Seiko hydraulic cylinders are made of.

OEM products

In addition to products designed to Koretsune Seiko's standard specifications, we also manufacture and sell custom products built according to customer-supplied drawings and fabricated on state-of-the-art equipment and quality control. We will also use our expertise in hydraulic equipment to prepare Value Assessment proposals for enhanced cost effectiveness. We welcome inquiries at any time.
