STS/STD tooth synchronous pulley is also known as semi-arc tooth synchronous pulley.

STS/STD gear synchronous pulley classification: S2M, S3M, S4.5M, S5M, S8M, S14M

STS/STD gear synchronous pulley Raw materials: Generally made of steel, aluminum alloy, cast iron, brass, and other materials. The inner hole has round hole, D-shaped hole, conical hole and other forms.

STS/STD tooth synchronous pulley surface treatment: natural oxidation, blackening, zinc plating, color zinc plating, high-frequency quenching and other treatment. Accuracy level depends on customer requirements.

1, the STS/STD gear synchronous belt produced by our factory is not only for the STS/STD gear synchronous belt of domestic equipment, but also can replace the imported STS/STD gear synchronous belt.

2, customized STS/STD gear synchronous pulley, please provide the pulley drawing (it is not necessary to draw the tooth shape size of the pulley in the drawing), our factory can also draw the pulley drawing according to the specifications provided by the user, the inner hole of the pulley, the keyway, the width and other dimensions for the user.

3, our factory STS/STD synchronous belt wheel can be processed according to user needs, and our factory can also develop drawings for users.
