High Temperature Belting (Heat Resistant Belts)

Dura-Belt’s High Temperature Belts are probably the only elastic belts that work well at hot temperatures. These round, heat resistant belts come in two options:
  1. Ultra High Temperature Urethane Belts. Tan color. 90A durometer. Works up to 230oF (110oC). Stretch 4%. Exceptionally strong, durable and long lasting, but relatively expensive. Available only as endless or connectable round belts. Not weldable in the field.

  2. Jacketed Spring Belts. Works up to 450oF (230oC). Stretch 20%. Available only as endless or connectable round belts.
Jacketed Spring Belts* are designed for light duty applications and are not recommended for use on pulley diameters of less than 2" (50mm). These belts are composed of an external plastic or rubber jacket and an internal metal spring. The heat resistant spring provides the elasticity, while the flexible jacket is actually under compression, so it does not have to be elastic.They come in two different temperature ratings:
