Feature 1: The product has embedded steel wire core, which is more cost-effective and has a wider range of applications.
Feature 2: There is no exposed steel wire core on the side of the opening to avoid scratching the opponent or injuring the operator.
Feature 3: It can be used in conjunction with the toothed plate for timing belt connection, linear guide rails, single-axis drives and other products, and is suitable for equipment with a high degree of automation.
Feature 4: Compared with chain drives, free-end timing belts are lighter, produce less noise, and do not require lubricants, making them cleaner.

Precautions
■Storage Precautions
①Avoid sunlight.
②Do not use in an environment with direct contact with water, solvents, oil, acid, alkali, ultraviolet rays, ozone, etc.
Especially do not allow oil to adhere to the belt, otherwise it will cause the belt to swell and significantly shorten the service life of the belt.
③Using temperature -20℃～60℃.
④Do not pile up in large quantities or bend forcibly.
⑤Do not place directly on the ground.
⑥Do not allow the belt to come into contact with chemicals.

Frequently asked question (FAQ)
- Question: After using the polyurethane timing belt for a period of time, it changes color. Will it affect its use?
- Answer: No, polyurethane belts may change color over time, but the strength will not be affected.
- Question: What kind of belt material is better for working conditions with high cleanliness requirements?
- Answer: Polyurethane belts are recommended, which have significantly improved dust drop compared to rubber belts.
- Question: Can the open belt be used for transmission after matching with the connecting tooth plate?
- Answer: It can be used for transmission and can only be used for linear reciprocating motion.
- Question: What are the two main types of polyurethane timing belts according to the interface form?
-
Answer:
Open type, the length of the open belt can be freely specified.
Closed type, the length of the connecting belt is processed with joints at both ends, and this type of connecting belt is only suitable for transmission function.
