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.
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.

Product Features
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.
Feature 4: Possesses a certain degree of conductivity.
Feature 5: Operating temperature range: -30 to 90℃ (MXL/XL/L/H), 0 to 80℃ (T5/T10).
Usage Method
■ Installation method for timing belt transmission
①Turn off the power supply, remove the protective cover, loosen the motor assembly timing belt, move the motor so that the belt is loose enough. The belt can be removed without prying. Never try to pry the belt down.
②Remove the old timing belt and check for abnormal wear. Excessive wear may mean that there are problems in the design or maintenance of the transmission device.
③Choose the right timing belt to replace.
④To clean the belt and pulley, wipe with a cloth dipped in a small amount of non-volatile liquid. Soaking in detergent or scrubbing the belt with detergent is not advisable. To remove grease, it is also undesirable to wipe with sandpaper or scratch with a sharp object. The timing belt must be kept dry before installation and use.
⑤Check the pulley for abnormal wear or cracks. If the wear is excessive, the pulley must be replaced.
⑥Check whether the pulley is linearly symmetrical. Linear symmetry of the pulley is essential for the operation of the timing belt, especially the timing belt transmission device.
Asymmetry of the pulley is shown as follows:
 Usage method Installation guide Complete selection Fit installation
⑦Check the remaining transmission device components, such as bearings and bushings, for symmetry, durability, lubrication and other conditions.
⑧Install a new timing belt on the pulley. Never pry or use too much force.
⑨Tighten to narrow the center distance of the transmission device until the tension tester detects that the belt tension is appropriate. Turn the driving wheel several times with your hands. Re-test tension.
⑩Tighten the assembly timing belt of the motor and correct the torque. Since any change in the center distance of the transmission device during operation will result in poor belt performance, it is important to ensure that all transmission components have been tightened.
⑪Start the device and observe the timing belt performance to see if there is abnormal vibration, and listen carefully if there is abnormal noise. It is best to turn off the machine and check the conditions of the bearing and motor.
Precautions
① Do not bend the timing belt by force.
It is strictly forbidden to bend the belt, which easily causes breakage
② Do not use in direct contact with water, solvent, oil, acid, alkali, UV, ozone, etc.
Do not directly contact water in operating environmentDo not use in acidic environmentsAvoid contact with alkaline solventsTry not to touch oil liquidsAvoid exposure to strong UV rays
③ Please avoid using or keeping at extreme high or low temperatures beyond the operating temperature range, or in humid environments.
④ During installation and maintenance, be sure to cut off the power supply and confirm that the machine is completely stopped before proceeding.
⑤ When there may be impurities, be sure to set the guard.
