Open Timing Belt STD S3M/S5M/S8M

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.

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.

■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.
