Optibelt's T5 27 (20-200ZA) is a type T5 synchronous toothed belt constructed with a knurled top (teeth) and a reinforced neoprene body. This high-quality, precision-crafted belt is designed to provide reliable, high-speed and low-vibration performance, even in the toughest industrial applications. It is resistant to water, oil, and dirt, as well as temperatures ranging from minus 22 F to plus 248 F. This belt is compatible with all Optibelt coupling systems and can be adapted to fit most non-Optibelt drives. It is designed to be vibration-frequency dependent, meaning that it will reach its maximum speed faster than traditional belts. The T5 belt comes in a variety of widths and lengths to fit specialized drive configurations.
