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 flexibility and load-bearing capacity, suitable for small-scale automated production line stepper motors, household appliance drive systems, packaging machinery feeding mechanisms, etc., meeting the transmission requirements for light to medium loads.

Pitch 3mm, with compact and small tooth shape, suitable for ultra-light and high-speed transmission scenarios in 3C electronic modules, miniature detection instruments, and small printer heads, etc. It operates without vibration and has extremely low noise.

Pitch 8mm, the tooth body strength and impact resistance have been significantly enhanced, capable of meeting the continuous transmission requirements in medium-load scenarios such as the main shaft of CNC machines, the driving unit of textile machinery, and logistics sorting equipment.

Pitch 14mm, it belongs to the RPP series of heavy-duty flagship models. It can withstand large torque output and is suitable for large industrial reducers, power systems of new energy equipment, heavy-duty automated production lines, etc., in medium to heavy-duty high-strength transmission scenarios.
