Conveyer Product Overview

The closed Conveyer belt is a belt that freely specifies the number of teeth and is suitable for long-distance timing transmission.
There is also a both sides cloth lined type suitable for cumulative transmission and noise reduction.

Conveyer Product Features

Feature 1: The Conveyer 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 closed belt to avoid scratching the workpiece or hurting the operator.
Feature 3: In addition to standard Conveyer belts, there are also both sides cloth lined belts, which can reduce the coefficient of friction between the conveying object and pulley, and lower the noise.
Feature 4: Regular sampling of Conveyer products is made to ensure a strength in the connection. (See the diagram below)
    Product Features  Product Features

・The steel wires are evenly arranged, the overall strength of the belt is stable, and the strength of the connection is comparable to MISUMI imported Conveyer products
・Used with MISUMI timing pulley idler, it has excellent engagement and smooth transmission
Product Features
Generic Conveyer products in the market are randomly selected from the market, and products of the same or similar styles are taken as the reference objects.

ConveyerThis Conveyer product is not suitable for non-backlash timing pulleys.
ConveyerWeight is a theoretical value for reference only, which may be different from the actual product.
ConveyerBecause of the welding process, there will be traces on the surface of the connection, and the allowable tension at the connection is weak, so please pay attention when selecting the Conveyer type.

Example of Conveyer Use

MISUMI Urethane Connecting belt

ConveyerThis Conveyer provides a reference for the use of urethane belts and is not a functional guarantee for actual use.
Equipment Name: Conveyer transfer device with different heights
Function Description:
  Transfer the workpiece through the motor roller, and use the cylinder mechanism so that the workpiece drop to the lower Conveyer for transmission. The purpose of transmission at different heights is achieved.

Conveyer Precautions

■ Conveyer Chemical-Resistant
Chemical resistance of long toothed timing belt

■ Precautions for Conveyer 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 belt.
③Operating temperature -20℃ to 60℃.
④Do not accumulate in large quantities or forcibly bend.
⑤Do not place it directly on the ground.
⑥Do not make the belt contact with chemicals.

Frequently asked question (FAQ)

Question: Is the joint of the joint processed long type timing belt particularly easy to break?
Answer: The joint of this belt is hot-melt connected, although the strength is lower than that of the body part, there will be no abnormalities such as breakage when used under normal tension. But it is not recommended to bend the joint, or breakage will be caused.
Question: What kind of belt is better to use under conditions that require high cleanliness?
Answer: The use of urethane belts is recommended, which has significantly improved dust drop, compared to the rubber belt.
Question: 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?
Answer: 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 countermeasuresto troubleshoot the equipment in use.
Question: What are the advantages of cloth lined timing belts compared to standard ones?
Answer: Cloth lined toothed belt reduce the coefficient of friction and reduce noise generation.
