Product overview
As a mechanism for transmitting the rotational power generated by the motor, timing pulleys and timing belts are commonly and widely used in design.
The engagement of timing pulley and timing belt teeth enables transmission and power transfer.
Localized production in China offers low prices while maintaining MISUMI quality.
Product feature
The S-type arc tooth economy series timing belt features a rubber material, with strengths in deviation prevention and wear resistance.■ S type circular tooth profile rubber timing belt (S2M/S3M/S5M/S8M/S14M)
Feature 1: The well-designed semi-circular crown tooth profile provides higher torque to accommodate high load transmission.
Feature 2: Reduces noise generated during high-speed operation.
Feature 3: The change in stress at the tooth peak results in a longer lifespan compared to traditional arc tooth designs.
Feature 4: Has a certain level of conductivity
Feature 5: Operating temperature range: -30 to 90℃ .
Features of the P-type high precision arc tooth domestic timing belt■ P type circular tooth profile rubber timing belt (P5M/P8M)
Feature 1: The well-designed semi-circular tooth profile provides higher torque to accommodate high load transmission.
Feature 2: The special concave tooth peak design further reduces the noise generated during high-speed operation.
Feature 3: The change in stress at the tooth peak offers greater accuracy compared to traditional arc teeth.
Feature 4: Possesses a certain degree of conductivity
Feature 5: Operating temperature range: -25 to 80℃ .
MXL, XL, L, and H trapezoidal tooth profile timing belts are suitable for light-load transmission applications■ Trapezoidal tooth rubber timing belt (MXL/XL/L/H/T5/T10)
Feature 1: Suitable for light-load transmission and standard torque transmission.
Feature 2: The tooth rubber uses chloroprene rubber to protect the tension member, providing excellent bending fatigue resistance, heat resistance, and oil resistance.
Feature 3: Economical and maintenance-free, making it an ideal replacement for traditional transmission methods.

The meaning of the belt number digits for timing belts varies depending on the type. For XL, the number of belt tooth is the belt number. Please note.
The belt circumference length is the core wire length.
The operating temperature range of the belt is -30 to 90℃.
The model engraved on the back of the product is the factory management No., which may differ from the product model.
MISUMI does not guarantee the brand of this product.
For the transmission capacity and design calculation method of the economy series timing belt, please refer to the national standard (GB) design manual.
The weight is a theoretical value and may differ from the actual product. For reference only.

Method of use
■ Mounting Method for Timing Belt Transmission
(1)Turn off the power, remove the protective cover, loosen the motor mounting bolts, and move the motor to make the belt sufficiently slack so that it can be removed without prying. Never pry the belt off.
(2)Remove the old belt and inspect for abnormal wear. Excessive wear may indicate a problem with the design or maintenance of the transmission device.
(3)Select the appropriate belt for replacement.
(4)For cleaning the belt and pulley, use a cloth dampened with a small amount of non-volatile liquid to wipe them. It is not recommended to soak the belt in cleaning agents or to scrub it with cleaning agents. Using sandpaper or sharp objects to remove grease is also not recommended. The belt must be kept dry before installation and use.
(5)Inspect the pulley for abnormal wear or cracks. If there is excessive wear, the pulley must be replaced.
(6)Check whether the pulley is aligned in a straight line. Proper alignment of the pulley is crucial for the operation of the timing belt, especially in timing belt transmission devices.
The illustration below shows pulley misalignment:
 Utilization method, installation description, complete selection guide, matching installation
(7)Inspect the remaining transmission device components, such as the symmetry, durability, and lubrication of the bearing and bushing.
(8)When installing a new belt on the pulley, never pry or use excessive force.
(9)Adjust the center distance of the transmission device until the tension tester indicates that the belt tension is appropriate. Rotate the driving pulley by hand several times. Recheck the tension.
(10)Tighten the motor assembly bolts and correct the torque. Since any change in the center distance of the transmission device during operation can lead to poor belt performance, be sure that all transmission device components are securely tightened.
(11)Start the device and observe the belt performance. Check for any abnormal vibration and listen carefully for any abnormal noise. It is best to turn off the machine and inspect the condition of the bearings and motor.
Precaution
(1) Do not bend the belt forcefully.
Do not forcefully bend the belt, as it may easily cause breakage.
(2) Do not use in environments where there is direct contact with water, solvent, oil, acid, alkali, ultraviolet rays, ozone, etc.
Direct contact with water is not allowed in the operating environment.Do not use in an acidic environment.Avoid contact with alkaline solvent.Try to avoid contact with oil liquid.Do not expose to strong sunlight or UV ray.
(3) Avoid using or storing in extremely high or low temperatures, or in humidity, that exceed the operating temperature range.
(4) During installation or maintenance, be sure to disconnect the power supply and confirm that the machine is in a complete stop state before performing any operation.
(5) If there is a possibility of impurity entrapment, be sure to install a guard.
