Open-Ended Timing Belt

Open – ended timing belts are continuous power – transmission components with teeth on one side. They are not endless loops like traditional timing belts. Instead, they are of a specified length and are often used in linear motion applications or when a non – looped belt configuration is required. They ensure accurate power transmission and synchronization between components by meshing with corresponding pulleys.

 

Various Tooth Profiles Available:

• Trapezoidal toothed: MXL, XXL, XL, L, H, XH, XXH
• T-toothed: T2.5, T5, T10, T20
• Arc toothed: HTD3M, HTD5M, HTD8M, HTD14M, HTD20M, GT2, GT3, GT5
• S-toothed: S2M, S3M, S4.5M, S5M, S8M, S14M
• Parabolic-toothed: P2M, P3M, P5M, P8M, P14M
• Y-toothed: G2M, G3M, G5M, Y8M

 

Materials:

• Thermoplastic Polyurethane (TPU): High wear resistance (3 – 5 times longer lifespan than rubber), oil resistance, flexibility (-30°C to 80°C tolerance), low noise (<60 dB), and easy processing (weldable/open – ended connections).
• Rubber: High elasticity, wide temperature tolerance (-60°C to 200°C for modified types), good water resistance (for synthetic rubbers like NBR), and high surface friction.
• Nylon: Excellent wear resistance and low friction coefficient, suitable for some low to medium load applications.
• Fiber Reinforcements: FLightweight (density: 1.44 g/cm³) yet extremely strong.
• PVC: Low cost, chemical resistance but poor cold tolerance (-10°C).

 

Types:

• Open-Ended: Engineered with specific materials to balance durability, precision, and adaptability for diverse industrial applications.
• Endless: Extruded without welding, making them the most robust construction type for power transmission applications.
• Green Fabric Reinforcement: Enhances flexibility and durability.
• Double-Sided: Designed with teeth on both sides, allowing for bidirectional power transmission.
• Thickened type: Structural Thickening: Extra-thick polyurethane (PU) or rubber layer to resist elongation under high tension.

 

Key Features:

• Non-closed Structure: Adjustable length via open ends, enabling easy installation/removal without disassembling equipment, suitable for linear motion or non-loop.
• Precision Meshing: Tooth engagement ensures zero slip, high transmission accuracy (exact speed ratio), and positioning errors as low as <0.1 mm in reinforced types.
• Low Maintenance: Self-lubricating, no need for oiling, and resistant to chemicals/fatigue (10⁶+ cycles).
• Environmental Adaptability: Options for food-grade, high-temperature, or corrosive environments.
• Quiet Operation: Smooth meshing reduces noise compared to chain/belt drives, ideal for medical/semiconductor settings.
