Synchronous Timing Belts 3GT Type

As a mechanism for transmitting the rotational power generated by the motor, synchronous pulleys and timing belts are commonly and widely used in the design.
Transmission and conveyance are achieved through the meshing of the teeth between the synchronous pulley and the timing belt.

			*The skip torque refers to the maximum torque the belt can withstand when tooth skipping occurs.

Feature 3: The glass fiber core provides the belt with high strength, excellent flexibility, and high tensile resistance.

(1) Do not bend the belt forcefully.

(2) Do not use in environments where the belt is in direct contact with water, solvents, oil, acids, alkalis, ultraviolet rays, ozone, etc.
 In particular, do not allow oil to adhere to the belt, as this may cause swelling and significantly shorten the belt's service life.(3) Avoid using or storing in extremely high or low temperatures or humid environments that exceed the recommended operating temperature range.
(4) When installing, maintaining, or inspecting, be sure to disconnect the power supply and confirm that the machine has come to a complete stop before starting any work.
(5) If there is a possibility that foreign objects may become caught, be sure to install a protective cover.
