Metric T-type synchronous belt gear tooth classification: T2.5, T5, T10, T20, AT5, AT10
Metric T-type synchronous pulley Raw materials: generally made of steel, aluminum alloy, cast iron, brass, etc. The inner hole has round hole, D-shaped hole, conical hole and other forms.
Metric T-type 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 metric T-type synchronous belt produced by our factory is not only for the metric T-type synchronous belt of domestic equipment, but also can replace the imported T-type synchronous belt.
2, user customized metric T-type synchronous pulley, please provide pulley drawings (the drawing can not draw the tooth shape size of the pulley), our factory can also draw pulley drawings according to the specifications provided by the user, the inner hole of the pulley, the keyway, the width and other dimensions.
3, our factory metric T-type synchronous belt wheel can be processed according to user needs, and our factory can also develop drawings for users.
