The OPTIBELT 31 AT10 28-200ZA belt is a high-performance, Kevlar-reinforced synchronous belt designed to deliver superior power transmission and improved belt life. It has an angle tooth profile, a 3M-12 tooth pitch, and is designed to provide superior efficiencies over traditional round/flat belts. It is constructed with an aramid tensile cord and an advanced compound rubber to ensure maximum strength and durability. The precise tooth profile allows for a precise fit and superior flexibility, making it ideal for applications that require precise synchronization, dynamic load carrying and low vibration. The belt is rated for speeds up to 4,000 feet per minute and temperature ranges from -34°F to 257°F.
