High-Pressure Hydrogen Tubes for Fuel Cell

This is a stainless tube which is used to deliver high pressure hydrogen gas from a tank. Maximum reliability is achieved by applying the technology of our fuel injection tube and by using a metal seal structure in which the joint is seamlessly molded. A high level of cleanliness is achieved inside the tube. It has been adopted in FCV (Fuel Cell Vehicle) that has attracted attention as a next-generation vehicle.

Amorphous Alloy Technology

Amorphous Alloy Technology

Amorphous alloy features high corrosion resistance, high wear resistance and high magnetostrictive performance. USUI’s new technology is a unique thermal spray with an ultra-rapid cooling method that works well with thin metal plate and row metal material.

Hollow Motor Shaft

Hollow Motor Shaft

USUI’s hollow motor shaft is a shaft that aims to reduce weight and improve cooling performance by making the inside of shaft hollow.

By combining the hollow pipe material and forged material using friction welding, it is possible to support various sizes and reduce weight while maintaining the required strength of the shaft.

We will propose the optimum motor shaft for electric vehicles that require weight reduction to increase efficiency.

Fan clutch

Fan clutch

Fan clutch is a fluid clutch to adequately control rotation frequency of the fan for engine cooling.

Temperature-sensitive bi-metal, which detects air temperature passing through the radiator, controls working silicone oil volume in the drive so that fan rotation frequency is kept adequately in controlled manner. It works to maintain the heat balance of the engine cooling system within a range and helps increase fuel economy and decrease fan noise, as well.

The combination of our Plastic Cooling Fan with Fan clutch could offer improved cooling performance with higher reliability.
From light duty to heavy duty trucks, USUI had commercialized various sizes of fan drives according to required cooling capacities on various engine out-put. At any time, for almost all sizes of engines, the best combination of fan and fan drive can be provided within USUI standard items.

Plastic Cooling Fan

Plastic Cooling Fan

In 1963 USUI successfully developed the world’s first plastic made fan for automobile engine cooling and has been manufacturing the Plastic Cooling Fan since then.

To provide a highly efficient plastic cooling fan with more airflow rate and less noise, we have developed a various type of blade configuration adopting airfoil profile and considering aerodynamic characteristic based on our years of experience and proprietary technology. USUI Plastic Cooling Fan has been used not only for automobile engines, but for almost all engines such as construction equipment, agricultural equipment, and general industrial equipment.

Apparently, the increasing stringent diesel emission regulations might ask for the higher performance on engine cooling.

USUI is continuously developing higher efficient plastic cooling fans with higher airflow to meet the requirement.
