Thickened Timing Belt

Thickened timing belt (or reinforced thick-back timing belt) is a heavy-duty synchronous belt engineered with increased cross-sectional thickness—particularly in the backing layer—to enhance tensile strength, load capacity, and durability while maintaining precise tooth engagement.

 

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:

• Polyurethane(PU): Known for its high tensile strength and excellent wear resistance, making it suitable for high-load applications.
• Rubber: Often reinforced with fibers (like fiberglass or polyester) for added strength and durability.
• Nylon: Excellent wear resistance and low friction coefficient, suitable for some low to medium load applications.
• Reinforced Fiberglass: For added strength and stability, incorporate reinforced fiberglass cords. These cords prevent stretching and maintain the belt’s integrity under high loads.
• PVC: Non-Reinforced, low production cost, suitable for budget applications.

 

Types:

Thickened type: Structural Thickening: Extra-thick polyurethane (PU) or rubber layer to resist elongation under high tension.

 

Range of thickness:

• Polyurethane(PU): The thickness can reach 5 to 10mm. This thickened polyurethane synchronous belt is used when higher load capacity and wear resistance are required, or when extremely high transmission accuracy is demanded and the working conditions are more complex, such as in the transmission of high-precision CNC machine tools and industrial robot arms.
• Rubber: The thickness can reach 6 to 12mm. In some heavy-load and high-impact transmission scenarios, such as the transmission systems of heavy-duty conveying equipment and mining machinery, thicker chloroprene rubber synchronous belts need to be used to withstand greater tensile and impact forces.

 

Key Features:

• Higher Torque Transmission: Supports 30–50% greater loads than standard belts of the same pitch.
• Heavy-Duty Performance: Designed to withstand continuous operation in harsh environments, such as industrial machinery, construction equipment, or high-tension drives.
• Durability in Harsh Conditions: Improved resistance to abrasion, chemicals, and extreme temperatures (depending on material choice, e.g., heat-resistant rubber).
• Reduced Maintenance Needs: Long service life due to durable materials and construction, minimizing replacement frequency in demanding applications.
• Extended Service Life:Resists cracking/abrasion in gritty or high-temperature environments.

 

Simple Structure:

Easy to install, easy to assemble and disassemble.

 

Application Scope:

Thickened timing belts are valued in power transmission in applications requiring high torque and impact resistance (e.g., presses, mining conveyors, agricultural machinery). Systems where standard belts face premature wear due to heavy loads or abrasive conditions.

 

Logistics service advantages:

• Fast Delivery.
• Precise delivery: Cooperating with multiple well-known logistics companies, we have rich delivery experience and can achieve precise delivery across the country, even in remote areas.
• Safe transportation: Professional shockproof packaging materials, such as high-strength cartons and shockproof foam, are used to ensure that the synchronous wheels are not damaged during transportation.
