HTD Rubber Timing Belt
High-Torque Synchronous Drive Solution for Industrial Power Transmission
The HTD Rubber Timing Belt is a high-performance synchronous belt designed for heavy-load and high-torque industrial applications. Featuring a curvilinear (arc-tooth) profile, HTD belts provide improved load distribution, reduced stress concentration, and stable power transmission compared with traditional trapezoidal tooth designs.
At Conxu, our HTD rubber timing belts are manufactured using precision molds, high-quality rubber compounds, and reinforced tensile cords to ensure consistent pitch accuracy, reliable torque capacity, and long service life in demanding industrial environments.
Product Overview
The defining feature of the HTD profile is its curvilinear tooth shape, which increases the contact area between belt and pulley. This design reduces tooth shear stress and improves torque transmission efficiency, making HTD belts ideal for medium to high torque applications.
Belt Structure & Materials
1.Belt Body Material
Our HTD belts are manufactured using high-quality synthetic rubber compounds such as:
• Chloroprene rubber (CR)
• EPDM (upon request for enhanced heat resistance)
Key properties:
• Excellent flexibility
• Good fatigue resistance
• Stable performance under cyclic loading
• Resistance to moderate oil and heat exposure
2.Tensile Cord Reinforcement
Inside the belt body, high-strength tensile cords ensure dimensional stability and load-carrying capacity.
Available cord materials include:
• Fiberglass cords (standard)
• Polyester cords
• Aramid cords (for higher load requirements)
3.Tooth Fabric Layer
The tooth surface is protected by wear-resistant fabric that:
• Reduces friction between belt and pulley
• Enhances tooth durability
• Improves noise performance
• Protects against abrasion

Key Performance Features
High Torque Transmission Capacity
The arc-tooth profile distributes load more evenly across the tooth surface, reducing stress concentration and improving torque capacity.
Precise Synchronous Operation
Positive tooth engagement ensures zero slip transmission and stable speed ratio.
Reduced Vibration and Noise
Curvilinear tooth geometry improves meshing smoothness compared with trapezoidal profiles.
Excellent Fatigue Resistance
High-quality rubber compounds and tensile reinforcement provide reliable long-term performance under cyclic loads.
Long Service Life
Controlled rubber formulation and precision manufacturing extend operational lifespan in industrial environments.
Stable Dimensional Accuracy
Accurate pitch control ensures reliable engagement with matching HTD pulleys.
Typical Applications
Textile Machinery
Packaging Equipment
Printing Machinery
Automation Systems
CNC Equipment
Industrial Conveying Systems
The HTD profile is particularly suitable for applications requiring higher torque than trapezoidal T-series belts.
Why Choose HTD Rubber Timing Belt Over Other Profiles?
HTD vs T Series (Trapezoidal)
• Better load distribution due to curved tooth design.
• Reduced stress concentration at tooth corners.
HTD vs RPP Profile
• Suitable for general heavy-duty industrial applications.
• RPP may offer optimization for specific performance scenarios, but HTD remains a versatile high-torque solution.
Rubber HTD vs PU HTD
• More cost-effective for many general industrial applications.
• Suitable for dynamic load conditions.
