Description
HTD 3M Open Timing Belt with Green Fabric is a specialized linear drive belt designed for high-precision, low-noise, and low-friction automation applications.
The core profile follows the 3mm High Torque Drive (HTD) curvilinear tooth standard, which ensures maximum power transmission and minimizes tooth jump,
Key Specifications & Geometry
- Tooth Pitch: 3 mm from the center of one tooth to the next.
- Tooth Shape: Curvilinear (arc) design for anti-slip performance.
- Total Belt Thickness: 2.40 mm.
- Tooth Height: 1.17 mm to 1.22 mm.
- Standard Widths: Available in 20mm,
-
Material Composition
- Base Material: Thermoplastic Polyurethane (PU) or Neoprene Rubber. PU offers superior wear and chemical resistance.
- Internal Tensile Core: Lined with high-strength Steel Wire Cords or Kevlar to prevent stretching under tension.
- Surface Layer: Covered with a specialized Green Polyamide (Nylon) Fabric bonded to the tooth side
-
Purpose of the Green Fabric
- Noise Reduction: Softens the mechanical contact between the belt teeth and the metal pulley, providing silent operation.
- Friction Reduction: Drastically lowers the friction coefficient, increasing system efficiency.
- Wear Resistance: Protects the underlying polyurethane or rubber core from premature abrasion.
- Smoother Engagement: Dampens vibrations at high linear travel speeds
