AT20 are reinforced polyurethane timing belts CONTI® SYNCHROFLEX AT profile with trapezoidal profile in a metric pitch for a higher load capacity.

The excellent bond between the hard-wearing polyurethane teeth and the constant-length galvanised steel tension members is the basic on which the high power output potential is built. The range of polyurethane compounds available also enables operation at low temperatures, in clean rooms and in the food industry.
