Products

• Roller: It is a core undercarriage component located at the top and bottom of the track of construction heavy equipment, supporting track links, facilitating turning movements, and distributing the heavy load of the main body. It is a consumable part that needs to be replaced every 6 months to 2 years depending on the degree of use.
• Idler: It is one of the undercarriage components of tracked construction equipment, playing a role in adjusting track tension and helping the track rotate smoothly. Along with rollers, it is an essential component for the stable operation of heavy equipment.
• Fuel Cell Components (Pressure Plate, Manifold): As a core component of hydrogen fuel cell stacks, it protects the cell stack and efficiently transfers heat. It is a future growth engine product with increasing demand due to the growth of the eco-friendly energy industry.
