Long Synchronous / STS Belts (LSB-R) are high-precision open-end and seamless timing belts engineered for extended-span power transmission, factory automation, and indexing conveyance. Manufactured with chloroprene rubber, glass fiber tensile cords, and low-friction nylon tooth facing, these belts serve as a lightweight, clean, and maintenance-free alternative to chain drives by eliminating the need for lubrication and reducing operational noise.
