Welded Endless & Open Ended Urethane Timing Belts

Details

Description

Urethane has become a workhorse in countless production situations around the world. Why? It is tough, can be made to any length, and stands up to the harshest industrial and environmental conditions. That makes it an outstanding value. Ask us about it.

Urethane BeltsOpen-ended roll lengths can be thermally welded to almost any required length, or fixed end to end with our clamping plates. Truly endless is the strongest construction, recommended for drive and high torque applications.
Urethane Construction and TeethMolded integrally the urethane protects the cords and provides a strong, flexible and excellent wear-resistant belt. Various urethane compounds are available depending on construction. To ensure correct engagement with the pulley grooves, the teeth are precisely formed and accurately spaced. They are precisely located so that the tooth root line lies substantially on the pitch line; thus, the tooth spacing of the belt is not altered by flexing. Low friction nylon fabric on the tooth and/or back side, is available on thermal weldable urethane.
Tensile MemberThe parallel cord tensile member is the secret of the belt’s enormous strength, its excellent flex life, and high resistance to elongation. Various tensile members are available depending on construction and belt pitch, such as Steel, Kevlar® and Polyester.
