Welded Endless and Open Ended Urethane Timing Belts

Versatile Power Transmission Solutions

Welded Endless and Open Ended Urethane Timing Belts offer a versatile and durable solution for motion control and power transmission applications. Built with high-quality thermoplastic polyurethane, these belts excel in strength, flexibility, and resistance to wear, making them ideal for demanding environments. Their design ensures precise motion control and reliable performance across a range of industries.

Traditional timing belts are available in two primary configurations: Welded Endless, which are seamless for high-tension applications, and Open Ended, which provide flexibility in length for linear motion and custom setups. Welded Endless belts are formed by joining open-ended belts to create a continuous loop, offering the strength of molded belts with customization options. Open Ended belts, supplied in rolls, allow for cut-to-length versatility in linear and conveying tasks.

Key Features

Seamless Construction

Welded Endless belts eliminate splices, ensuring consistent performance in synchronized applications.

Durable Urethane Material

Resists abrasion, oils, and chemicals, enhancing longevity.

Reinforced Tension Members

Options like steel, aramid, or Kevlar cords provide high tensile strength and minimal stretch.

Precision Operation

Designed for accurate and consistent motion transfer in power transmission.

Customization Options

Available in various lengths, widths, tooth profiles, and backings to meet specific application needs.

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.
