Precautions
(1) Do not bend the belt forcefully.
Belt must not be bent
(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.
Do not allow the belt to come into contact with waterDo not allow the belt to come into contact with acidic liquidsBelt must not come into contact with alkalisBelt must not come into contact with oily substancesDo not use the belt in environments with strong ultraviolet light
(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.
Example of Use
Example of Use DiagramInstructions for Using Timing Pulleys and Timing Belts
Timing belt transmits rotational force between the motor and the shaft(1) For driving (transmitting motion from the driving pulley to the driven pulley)
Timing belts are used for repetitive motion with high positioning accuracy where the conveyed object does not rotate(2) For conveying (used for repeated motion with high positioning accuracy requirements where the conveyed object does not rotate)
Example of Use DiagramInstructions for Using Timing Pulleys and Timing Belts
Case study of using two timing belts to convey sheet materials(3) For conveying (using two timing belts to transport sheets)
Methods and case studies of using conveyor belts for lifting and repeated positioning movements(4) For traction conveying (the belt grips the workpiece for transport)

Frequently asked question (FAQ)

Question: If the timing belt is damaged after only a very short period of use, does it indicate a quality issue with the belt?
Answer: Timing belts are standard products, and it is very rare for individual quality issues to occur within the same batch. Customers are advised to refer to Main Causes of Premature Damage and Corresponding Countermeasures to check the operating conditions of their equipment.
Question: Is there a tolerance range for the length and width of the timing belt?
Answer: Yes, for length and width tolerances, please refer to the Belt Tolerance Table.
Question: Why is there a discrepancy between the order model of the timing belt and the label or marking on the actual belt received?
Answer: When ordering, the model number is the MISUMI product model. The label on the belt or the printed model number on the belt surface is the belt manufacturer's model number, which may vary depending on the manufacturer, but this does not affect the product itself.
Question: Can the timing belt be further processed?
Answer: The circumference of the timing belt cannot be further machined, but the width can be partially machined as needed.
