Redflex GEN III belts are made from an advanced red polyurethane compound that provides up to 50% longer flex fatigue life, enhanced shock absorption, improved abrasion resistance, and a higher continuous operating temperature (+100°C vs +80°C) compared to standard polyurethane timing belts. They are designed for the most demanding high-speed, high-cycle, and elevated-temperature applications.

GEN III belts can operate continuously at temperatures from -30°C to +100°C, compared to +80°C for standard polyurethane. Short-term peak temperatures up to +120°C may be tolerable depending on load conditions. This makes GEN III the right choice for drives in elevated-temperature environments such as near ovens, dryers, heat-treating equipment, or in hot ambient conditions.

GEN III belts provide up to 50% longer flex fatigue life compared to standard polyurethane under equivalent operating conditions. The improvement is most significant in high-speed, high-cycle applications where heat generation accelerates standard belt degradation. In 24/7 production environments, this translates to significantly longer intervals between belt replacements.

GEN III compound is available in AT3, AT5, and AT10 curvilinear profiles, ATP10 high power profile, and T5 and T10 trapezoidal profiles. These cover the most common pitches for high-speed and high-dynamic applications. Contact Texas Belting at 888-203-2358 for availability in other pitches or custom configurations.

Yes. GEN III belts use the same tooth profiles and dimensions as standard polyurethane belts. They are a direct drop-in upgrade on existing AT, ATP, and T-Series pulleys. No drive modifications are required. Simply replace the standard belt with a GEN III belt of the same profile, width, and length.

In applications with continuous high-speed operation (high-speed packaging lines, printing presses, textile machines), the extended service life typically saves 2 to 3 times the cost premium through reduced downtime and replacement frequency. For moderate-duty applications running at standard temperatures and moderate speeds, standard polyurethane is more cost-effective. Contact Texas Belting at 888-203-2358 to discuss whether GEN III is justified for your application.

Currently, GEN III high-performance compounds are separate from FDA-compliant materials. For food processing applications requiring elevated temperature resistance, contact Texas Belting to discuss the best material option for your specific temperature and compliance requirements. Standard FDA-grade polyurethane operates to +80°C.

Consider GEN III if your application involves any of the following: belt speeds above 30 m/s, ambient temperatures above 60°C, continuous 24/7 operation with no scheduled stops, acceleration rates above 20 m/s², drives with heavy shock loads or sudden start/stop cycles, or if you are experiencing premature belt failure with standard polyurethane compounds. If none of these conditions apply, standard polyurethane is typically sufficient.
