Developing products that solve social issues
－Protecting the future through technology－

Through globally aligned research and development activities, the Daido Metal Group responds to diverse social demands and customer needs related to carbon neutrality and a sustainable society.
At the same time, we actively pursue opportunities to challenge ourselves through planned new product development and technical research, contributing to the advancement of global society.

Main Initiatives

Contributing to Carbon Neutrality

【Bearings with a Polymer Surface Overlay】

The ability to perform reliably in harsh operating environments, such as idling stop, is essential. We have developed bearings
with a polymer surface overlay that provides low-friction characteristics.
By applying a polymer material containing solid lubricants to the bearing surface, wear resistance and low-friction performance are improved. This contributes to enhanced automotive engine energy efficiency and reduced CO₂ emissions.

【Supplying a Hydrogen Engine】

The use of hydrogen energy to achieve carbon neutrality is gaining increasing attention.We are conducting verification activities to expand the market for hydrogen engines, and in November 2023, a Toyota HiAce equipped with our bearings in its hydrogen engine began public road trials in Australia. The demonstration run was completed as scheduled in January 2025, and it was confirmed that there were no problems with our company parts. In the future,we are working to promptly predict, verify, and resolve challenges such as engine oil alternations and abnormal combustion that can occur during hydrogen combustion.

Renewable Energy

【PEEK Polymer Bearings】

As hydropower generation output increases, the load on bearings also rises, making heat deformation from frictional heat a key challenge. We have developed DAIPEAK, a sliding bearing material with outstanding load capacity and seizure resistance, and we are continuing efforts to further enhance its performance. This high load capacity enables more compact bearing designs, reducing energy losses and contributing to smaller, more efficient equipment overall.

            Hydroelectric Power Generation

Replacing bearings in a wind turbine typically requires removing and reinstalling the blades, resulting in downtime and replacement costs. Our bearings are designed to be separated into individual parts, allowing replacement inside the wind turbine nacelle without removing the blades. The superior wear resistance of DAIPEAK sliding material is expected to greatly extend bearing service life.

【Development of Graphene Thick Film Electrodes】

The next generation of electrodes requires more efficient and resource-saving materials.We are developing a thick film electrode using the new material Gmit®. By incorporating carbon nanochips as spacers to control the graphene layers, we have successfully applied our thick film production technology to create a thick film sheet. This electrode achieves approximately three times the energy density of conventional carbon capacitor electrodes, contributing to energy savings.

Protection of the Environment

【Solid Lubricant Dispersed Bearing】

We have developed a wide variety of bearings to support all kinds of sliding and rotating parts and to improve energy efficiency. Thermalloy®, a bearing material in which a solid lubricant is dispersed, can be used in high-temperature, high-humidity, dusty, and vacuum conditions - unlike conventional bearings. Because it does not require grease or lubricate oil, it offers a long, maintenance-free lifespan and is also environmentally friendly.

Reuse of Water Resources

【Deionisation Equipment】

The protection of water resources and the reuse of wastewater from industrial processes are increasingly important issues. We are conducting research and development on deionising water treatment equipment that utilizes electric double-layer capacitor technology. This device offers high durability, thanks to its low chemical use and minimal wastewater discharge, and is currently undergoing internal testing and external trials. Our goal is to further reduce environmental impact by enabling the reuse of water resources.
