Application Areas
Industrial Machinery and Manufacturing Equipment: Used in industrial scenarios such as rubber machinery, laser cutting machines, heat shrink packaging machines, painting production lines, and smelting equipment, especially suitable for devices requiring high speed and lightweight design. Plays a critical role in transmission functions within CNC machinery, textile machinery, welding machines, and steel bar drawing machines.
Power Tools and Small Equipment: Commonly found in power tools (such as handheld drills, grinders) and small gearboxes, precision instruments. Its thin-section design (thickness ranging from 2.7 to 4mm) makes it ideal for compact spaces.
Automotive and Automation Fields: Utilized in automotive components like steering systems, braking systems, and gearboxes. Also suitable for industrial automation equipment, robot joints, and hydraulic transmission systems.
Home Appliances and Daily Life Equipment: Widely applied in washing machines, air conditioner compressors, and food processing machinery (such as heat presses, ironing machines).
