Open Timing Belt XL/L/H

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.

The total length is (number of teeth × tooth pitch).
kgf＝N×0.101972

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.

■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.
