Based on the existing platform products and our product design experience, our products and design/ development capability can meet the needs of fuel cell systems and solve the current pain points.
Oil Free
Lubricating oil will poison the fuel cell stack, so the oil free bearing is necessary for fuel cell system.
01
High Efficiency
The parasitic power of air compressor is huge, and its efficiency directly affects the performance of fuel cell system
02
Downsizing Cost
Fuel cells are limited by their power density and cost, so down size and low cost will contribute to the industrialization of fuel cell vehicles
03
Low Noise
Air compressor is one of the biggest noise sources of fuel cell system, and reducing the noise of air compressor will greatly reduce the noise of the whole system
04
Surge Line in Low- Flow Area
The fuel cell can run efficiently under the condition of low flow and high pressure ratio
05
Dynamic Response Capability
When the demand power changes, the air flow rate and pressure need to be adjusted without delay to track the change of the output power

CORE TECHNOLOGY
Air bearings utilize a thin layer of pressurized gas to maintain separation between bearing surfaces during high-speed operation. This pressurized gas must be robust enough to support both static loads, such as the weight of the shaft, and the imbalances of dynamic loads.
Dynamic loads arise from the combination of the shaft's unbalanced mass and critical modes. To a certain extent, rotodynamic analysis can predict these dynamic loads, which can be further reduced through precise balancing procedures and adjustments to the bearings' stiffness and damping characteristics.
In recent years, there has been a surge in demand for turbomachinery with shaft speeds exceeding 100 m/s. This trend is driven by the need for more compact machines that operate at faster speeds to achieve high-power outputs.

A substantial reduction in power consumption
02
Longer bearing life
03
The elimination of complex cooling systems.
Additional benefits include low noise, maintenance-free operation, lower vibrations, and lower operating costs.
EXAMPLE FOIL BEARING APPLICATIONS
Air-Cycle Machines
This common foil bearing application provides oil-free air for high.Speed systems such as fuel cell blowers and turbochargers.
Oil-Free Compressors
For compressors involved in heat exchange, eliminating lubricantfrom the process improves thermal performance, such as HVAC andcryogenic applications.
High-Speed Motors
With the advent of higher-speed drivers, foil bearings let you run asfast as rotordynamics will allow.
Gas Turbines
High-temperature-capable materials and coatings facilitatelubricant free bearing support for combustion systems.
We have developed and applied a double-layer coating technology aimed at enhancing both wear resistance and adhesive force while maintaining its unique slippery characteristics. This double-layer coating not only boasts excellent durability, effectively resisting wear and tear,but also exhibits strong adhesion capabilities, making the bond between the coating and the substrate even stronger. What's more, it retains the original slippery properties, ensuring smoother operation and greatly improving the start-stop life. The unique advantages of this double-layer coating technology undoubtedly bring unprecedented innovation and progress to relevant industries.
