OPEN END POL YURETHANE TIMING BEL T S
POWERING GLOBAL INDUSTRY
Open Ended Timing Belts are linear extruded thermoplastic polyurethane (TPU), reinforced with high strength reinforcement cords. Available in imperial and metric pitches and in a number of tooth shapes. Our standard product is made with polyester thermoplastic polyurethane, however polyether polyurethane is also available on request.
Our belts are made with several reinforcement options, however our standard product is made with Zinc coated steel cords.
Nylon can be added to the tooth and conveying side of the belt, providing benefits such as low noise and reduced slip stick on the tooth side and easy glide benefits on the top side for accumulation conveying applications.
Anti-static facings are also available for use in applications where an electrical charge build-up would be detrimental to the product conveyed or the application environment.

POWERING GLOBAL INDUSTRY
Thermoplastic Polyurethane Flex (Truly Endless) Timing Belts are manufactured with helically wound cords. They are especially suited for power transmission and conveying applications with high torque loads and speed. The addition of a nylon fabric on the teeth during production enhances the running properties for specific applications and reduces noise. An extra thickness of special backing is also possible on the back of the belt, offering extra protection against abrasive or heavy products being conveyed. The tensile member cord is continuously spiraled across the width of the belt, increasing power transmission capability and breaking strength - unlike spliced belts where the cords are cut to make the splice.

POWERING GLOBAL INDUSTRYFDA silicone materials allow for use in the transport of hygienic goods and medical related parts and components. Silicone is an excellent cover material where the use of glues and adhesives are present in product manufacture. Neoprene rubber can be formulated to provide good chemical and wear resistance, anti-static features, and self-extinguishing (UL94V) non-flammable properties for use in precision conveying applications. Our Neoprene Rubber Coatings can be applied to various substrates. Coated belts can be further modified with holes to assist in vacuum draw applications.
COATINGS
Silicone on woven polyester with holes and slots Silicone coated foam on a polyurethane timing belt Megadyne has developed state-of-the-art processes for applying silicone and neoprene to a wide range of belt
substrates; both stable and elastic. Coated belts are commonly used in product transport applications where environmental conditions such as temperature would have an adverse effect on fabricated covers. Additionally, the coating of certain material substrates allows for the finished product to move across low profile conveyors where designs such as knife edge pulley transports are common.

MOLDED COVERS
Megadyne offers a wide selection of covers for every customer’s individual needs. For our molded covers, we mold uncured rubbers onto base belts, autoclave and grind them to gauge, producing a seamless cover and ensuring a uniform structure. This creates a belt without bumps, splices, seams or hard spots, drastically reduces delamination, increasing belt life and creating uniform wear surfaces.
In addition to many industry standard materials which can be molded, BCA has
POWERING GLOBAL INDUSTRY
developed its proprietary DuraTaq™ cover, which offers a very high coeicient of friction and low wear resistance. It's the perfect choice for applications requiring superior wear performance in diicult abrasion settings, leading to extended life and greater machine uptime performance.
Molded covers can be further modified with holes, slots, ground impressions, grooves, pockets and other designs to assist in enhancing product handling and movement. See our modification page for additional details.

In many cases, the chosen belt substrate and cover material do not lend themselves to a cured homogeneous bond. In these cases, depending on the base belt type we can fabricate or extrude a cover to assist in product handling.
Cover materials available offer enhanced performance in applications where: high or low friction is desired, non-marking of product conveyed is essential, heat resistance is required, compressibility is essential for fragile
