Open Timing Belt STD S3M/S5M/S8M


Product Overview
Open belts are components that transmit the rotational power generated by the motor.
They achieve transmission and delivery through the engagement between the timing pulley and the timing belt teeth.
Open belts are suitable for reciprocating motion and are equipped with a variety of connecting metal parts.

Product Features
Feature 1: The product has embedded steel wire core wire, which is more cost-effective and has a wider range of applications.
Feature 2: There is no exposed steel wire core wire on the side of the opening to avoid scratching the opponent or injuring the operator.
Feature 3: It can be used with toothed plates for timing toothed belt connection, linear guides, single-axis drives and other products, and is suitable for equipment with a high degree of automation.
Feature 4: STD tooth transmission has high precision and is suitable for high torque transmission. You can also choose S3M type, which is suitable for small precision equipment.
Feature 5: Compared with chain drive, the free-end timing toothed belt is lighter, produces less noise, and does not require lubricants, making it 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: It can be used for transmission and can only be used for linear reciprocating motion.
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.
