AT5 GEN III CONTI® SYNCHROFLEX polyurethane timing belt

Standard version:

  • Single-sided
  • High performance polyurethane mixture (colour: red) for higher performance, longer longevity and better temperature resistance up to 100 °C
  • Bifilar design of the steel tension members for optimised straight belt run
  • Higher packing density of tension members for a higher overall stiffness
  • Highly flexible tension member design for a better flexibility (E tension members)
  • High performance AT profile with metric pitch and trapezoidal teeth
  • Preferred timing belt widths: 6, 10, 16, 25, 32, 50, 75, 100 mm

On request:

  • In-between widths, larger widths and other dimensions
  • Reinforced belt back

Please consider our warranty.

b& = {F_U \over {z_e \cdot F_{Uspez}}} && F_U [N] \\
b& = {100 \cdot M \over {z_1 \cdot z_e \cdot M_{spez}}} && M [Nm]\\
b& = {1000 \cdot P \over {z_1 \cdot z_e  \cdot P_{spez}}} && P [kW]
