Urethane timing belt has changed color after being used for a period of time, will it affect the use?

No, the urethane belt may change color over time, but there is no effect on strength, etc.

What kind of belt is better to use under conditions that require high cleanliness?

The use of urethane belts is recommended, which has significantly improved dust drop, compared to the rubber belt.

The timing belt has been broken after use for a very short period of time. Is there a problem with the quality of the belt?

The timing belt is a standard product, and the same batch of products have very few individual quality problems, please refer to Main causes of premature breakage and corresponding countermeasures to troubleshoot the equipment in use.

Can alteration be made to the timing belt?

Alteration cannot be made to the circumference of the timing belt, and partial alteration can be made to the width.

Is there a recommendation for metal connectors for free-end toothed timing belt?

Yes, the applicable connecting metal parts corresponding to each tooth shape are listed in the Specification Table, which can be purchased from MISUMI, please use as reference.

What are the two main types of timing belts according to their functions? What is the role?

Timing belts are mainly divided into transmission type and driving type. For transmission type, the load can be placed on the timing belt surface for transmission. For driving type, no load is carried, and only the role of transmitting torque is played, which is similar to the role of chain.

Which tooth type of the timing belt has the smallest clearance? What will it affect?

The arc tooth type has minimum clearance, which can improve such indicators as positioning accuracy and rigidity.

Please note that the MISUMI Pune office and warehouse will be closed on November 20th due to the state election.

Product Overview

The toothed timing belt is a component that transmits the rotational power generated by the motor. Driving and transmission are realized through the engagement between the teeth of timing pulleys and timing belts.
The free-end toothed timing belt is suitable for reciprocating motion and can be used in conjunction with metal parts for economy series timing belts.

Product Features

Feature 1: The product has built-in steel core wire, which is more cost-effective and has a wider application range.
Feature 2: There is no exposed steel core wire on the side of the timing belt to avoid scratching the workpiece or hurting the operator.
Feature 3: It can be used in conjunction with tooth plates for connecting toothed timing belts, linear guides, single-axis drives and other products, and is suitable for equipment with a high degree of automation.
Feature 4: STD toothed transmission accuracy is high, suitable for high torque transmission. S3M type is also available for small precision equipment.
Feature 5: Free-end toothed timing belts are lighter and produce less noise than chain-driven ones and cleaner without lubricant.

Precautions

■Precautions for storage
① Avoid sunlight.
② Do not use in direct contact with water, solvent, oil, acid, alkali, UV, ozone, etc.
In particular, do not make oil adhere to the belt, otherwise it will cause the belt to swell, significantly shortening the life of the timing belt.
③ Operating temperature -20℃ to 60℃.
④ Do not accumulate in large quantities or forcibly bend.
⑤ Do not place it directly on the ground.
⑥ Do not make the belt contact with chemicals.
