The STD metric circular tooth-type synchronous belt is a standardized product specifically designed for high-precision and small-space transmission scenarios. It is made of high-quality chloroprene rubber or polyurethane as the base material, with a high-modulus glass fiber tensile layer embedded inside, and the tooth surface is covered with nylon wear-resistant fabric. The tooth shape strictly follows the metric standard, covering four sub-specifications: S3M, S5M, S8M, and S14M. With its core advantages of precise tooth shape, efficient transmission, and compact layout adaptation, it is widely used in the light to medium-load transmission fields such as 3C electronic devices, precision instruments, small automated production lines, and medical devices.

Pitch 5mm, balancing precision and load-bearing capacity, suitable for stepper motors of small automated production lines, driving mechanisms of household appliances, etc., meeting the transmission requirements for light to medium loads.

Pitch 3mm, extremely small tooth shape, suitable for ultra-light load and high-speed transmission scenarios in miniature motors, precision instruments, printer heads, etc. The transmission noise is extremely low and the operation is smooth without vibration.

Pitch 8mm, enhanced tooth strength, excellent impact resistance, capable of meeting the requirements for continuous transmission in medium-load scenarios such as CNC machine accessories and small-power main shafts of textile machinery.

Pitch 14mm, it belongs to the heavy-duty model in the STD series. It can withstand large torque and is suitable for auxiliary transmission of large-scale automated equipment, power systems of small new energy devices, and other scenarios.
