                    • ★Rounded teeth supply low backlash and wear, as well as good load distribution to ensure high performance, torque force and precision tooth meshing. The traits provide excellence in rotary and linear positioning, and power transmission applications.

                      ★ Deep tooth engagement causes slightly noise, but it provides greater transmission power.

                      ★Small tooth pitches are applied for high torque conveying.

          • Ordering example
            • Structure:

              	Back 	Hard-wearing PU backing protects cords from exposing at belts edges. Also belts are thin enough to lower heat and increase belt life.	Body Highly flexible polyurethane (PU).  Because of the casting method and the capillary effect, allowing the superior bonding with tensile cords.  Integrally formed profiles, providing belts with accuracy and strength.	Tooth 	Hard-wearing and tough PU teeth and backing are integrally formed and resistant to break. For this reason, cords are completely protected. The teeth rigidity and strength enhance shear resistance against tooth slip.	Tensile cords Galvanized steel cord and aramid tensile members are available.    A: steel cord 	It will not stretch or fatigue during continuous operation, providing tooth shear strength and load capacity under shock applications.  	Stainless steel cord is also available and particularly suitable in the erodent environment.  B: aramid fiber 	Since aramid tensile cord combines extraordinary strength and superior shock load capacity, it is flexible and counterbending; therefore, it is favorable for oridinary or non- magnatic driver.  	Compard with steel cord, lightweight is characteristic of aramid fiber.

              ● Cleanness
                High wear resistant PU minimizes dusting and is especially suitable for clean rooms, food and beverage industry.
              ● Non-Slip
                Belts teeth mesh with pulleys, assuring the smooth transmission against tooth jump, friction and speed variation.
              ● Free of Maintenance
                Compared with chains or gears, the cost of lubrication and maintenance is few.  
              ● Low Pre-tension
                Only low initial tensioning, motor and bearing loads are minimized, enjoying longer belt life.

              ●

              Constant Tension
                No retensioning required.
              ●

              A wide Range of Load Capacities and Speeds

               
              • Speeds range from 0 to over 20000 RPM.
              • Ideal for low, medium and high power range. For example, sustained transmission of high torque level at low speed, high power transmission at high speed or shock loads. 
              • High degree of efficiency: allows friction-free drives with an efficiency of 99% and also lowering the operation costs.
              ● Dimensional Stability
                Excellent structure and bonding , constant belt thickness and width enable smooth running.  
              ●

              Oil Resistance

                Conditionally resistant to oils, grease and fuel.
              ●

              Temperature Range

                Under room temperature, it is from -20°C to 95°C.
              ● Climate Resistance
               
              • Suitable for tropical climates.
              • Resistant to aging, ozone, hydrolysis and UV.
              ● Bending Resistance
               
              • Special and high quality component.
              • Belts are suitable for bending applications.   
              ● Environmental Friendly
               
              • Certificated by RoHS compliance.
              • Low dusting, provided non-marking structure.
              • Free carbon black.
              ● Antistatic
               
              • Antistatic belt is made-to-order
              • The whole one is electronically conductive and conforms to ≤ 109 Ω
              • Resistance remains steady and will not lower following a long-run operation
              ● Acid and Alkali Resistance
                Conditionally resistant to acid and alkali
              ● Wear Resistance
                Ten times higher than rubber belts.
              ● Anti-solvent
                Conditionally anti-solvent.
