Each generation is different – GEN III is better. Its combination of highly rigid steel cord tension members and abrasion-resistant polyurethane make the CONTI® SYNCHROFLEX GEN III polyurethane timing belt incredibly accurate and hard-wearing. The CONTI® SYNCHROFLEX GEN III ensures maximum precision and reliability, even in temperatures of up to 100°C. GEN III has increased power transmission by 25% compared to the AT/ATP standard. The belt also has an economic advantage: All CONTI® SYNCHROFLEX GEN III polyurethane timing belts are suitable for use with standard AT/ATP synchronous pulleys.
