Endless manufactured rubber timing belts are produced without connecting links and enable synchronous power transmission with a constant gear ratio. Due to their homogenous structure, they are suitable for high-performance drive systems, especially with high torque, extreme acceleration, and low rotational speeds or high belt speeds.
Compared to open-ended timing belts or double-sided timing belts, they offer higher performance and operational reliability. They are suitable for continuous drives in mechanical engineering, conveyor technology, or automated systems.
Depending on the application, polychloroprene or HNBR compounds are used. These are characterized by high tensile strength, good flexural properties, and low running noise. Furthermore, they offer good vibration damping and are temperature resistant from -40 °C to +120 °C and electrically conductive according to ISO 9563.
For detailed technical specifications of the individual timing belts, please refer to the respective data sheet.

More informations
Endless rubber timing belts are manufactured in one piece without splices. This creates a homogeneous structure that enables uniform power transmission, high dimensional accuracy, and smooth running.
Endless rubber timing belts offer consistent, uninterrupted power transmission, high tensile strength, and exceptionally smooth operation. They are durable, require minimal maintenance, and enable high efficiency with virtually frictionless operation.
They are especially suitable for high-performance drives, such as those involving high torques, high belt speeds, or dynamic applications with strong acceleration forces. Typical applications include mechanical engineering, conveyor technology, and industrial drive systems.
Endless rubber timing belts are available in HTD, STD, CTD, inch, and HOT profiles. The profile selection depends on torque, speed, and power requirements to ensure optimal power transmission and smooth operation in the drive.
Endless rubber timing belts consist of polychloroprene or HNBR (hydrogenated nitrile rubber) with tensile members made of glass cord or aramid, as well as an abrasion-resistant polyamide fabric.
Endless rubber timing belts have a continuous structure without joints. This ensures particularly even power transmission, higher dimensional accuracy, quiet operation, and lower preload compared to finite or double-toothed belts. They are more durable, require less maintenance, and enable high speeds and dynamic applications.
HNBR timing belts are used in applications with higher thermal and mechanical loads. They offer better resistance to temperature, oil, and wear, making them suitable for demanding industrial applications.
Depending on the material, they are suitable for temperatures from approximately -30 °C to +130 °C and can also be used in demanding environments.
