Trapezoidal tooth synchronous belt XLThe trapezoidal toothed synchronous belt is a transmission component featuring a trapezoidal tooth structure, typically made of rubber or poly
Designed with British pitch, the product line includes models such as MXL, XL, L, H, XH, XXH, and T series, complying with China's GB/T 11616 and ISO 5296 standards.
Its structure incorporates nylon elastic fabric for tooth protection and glass fiber cores to ensure dimensional stability, offering flame retardancy, oil resistance, and corrosion resistance.
With a transmission efficiency of 98%, it supports linear speeds up to 40 m/s, enables multi-axis operation, and requires no lubrication.
Widely used in industrial applications such as printing machinery, CNC machine tools, food packaging equipment, textile machinery, and medical devices.
