The Apexcoupling Double Sided Trapezoidal Tooth Synchronous Belt series offers a comprehensive range of high-performance double-sided toothed belts designed for applications requiring power transmission from both sides of the belt simultaneously. Featuring teeth on both the top and bottom surfaces, these belts enable bidirectional power transmission and are ideal for reversing drives, serpentine drives, and compact transmission systems where space is limited.

Available in a wide range of pitch profiles – D5M (5mm pitch), DL (9.525mm pitch), DH (12.7mm pitch), DXH, DT5 (5mm pitch), DT10 (10mm pitch), and DT20 (20mm pitch) – these belts are manufactured from premium rubber/neoprene with high-strength fiberglass tension cords for exceptional tensile strength and dimensional stability. OEM/ODM customization is fully supported – custom lengths, widths, and special profiles available.

✅ Double-sided toothed design – bidirectional power transmission from both belt sides. Trapezoidal tooth profile – reliable, slip-free synchronous engagement. Premium rubber/neoprene – excellent wear resistance, oil resistance, and ozone resistance. Fiberglass tension cord – high tensile strength, dimensional stability, zero stretch. Wide pitch range – D5M, DL, DH, DXH, DT5, DT10, DT20. OEM/ODM customization – custom length, width, profiles. 3-year warranty – quality assured.

Double Sided vs Single Sided – Why Choose Double Sided?

✅ Choose double sided for applications requiring power transmission from both sides of the belt, reversing drives, serpentine drives, and compact transmission systems where space is limited .

Product Structure

1. Rubber/Neoprene Body – Premium synthetic rubber with excellent wear resistance, oil resistance, ozone resistance, and heat resistance .

2. Fiberglass Tension Cord – High-strength cord embedded in the belt providing tensile strength, dimensional stability, and zero stretch .

3. Double-Sided Tooth Profile – Trapezoidal teeth on both top and bottom surfaces for bidirectional power transmission.

4. Nylon Tooth Surface Fabric – High-elastic fabric covering the teeth to reduce friction, noise, and wear .

💡 How it works: The double sided timing belt features trapezoidal teeth on both the top and bottom surfaces, allowing it to engage with pulleys on both sides simultaneously. This enables bidirectional power transmission – power can be transmitted from both sides of the belt, making it ideal for serpentine drives, reversing drives, and compact transmission systems where space is limited and multiple components need to be driven from a single belt.

Why Choose Apex Coupling for Double Sided Timing Belts?

FAQ

Q: What is a double sided timing belt?
A: A double sided timing belt (also called a double-sided synchronous belt or dual-sided timing belt) features teeth on both the top and bottom surfaces, enabling bidirectional power transmission from both sides of the belt. It is ideal for reversing drives and serpentine drive systems .

Q: What pitch profiles are available?
A: Standard pitch profiles include D5M (5mm), DL (9.525mm), DH (12.7mm), DXH (22.225mm), DT5 (5mm), DT10 (10mm), and DT20 (20mm) .

Q: What materials are used?
A: The belt is made of premium rubber/neoprene (chloroprene) with high-strength fiberglass tension cords and nylon tooth surface fabric .

Q: What is the difference between D5M and DT5?
A: Both have a 5mm pitch. D5M refers to the metric synchronous belt profile (HTD/curvilinear style), while DT5 refers to the trapezoidal tooth double-sided timing belt series .

Q: What is the difference between DL, DH, and DXH?
A: These are imperial pitch profiles: DL = 9.525mm pitch (0.375″), DH = 12.7mm pitch (0.500″), DXH = 22.225mm pitch (0.875″) .

Q: Can the belt be customized?
A: Yes. We offer OEM/ODM customization – custom length, width, and special profiles.

Q: What are the common applications?
A: Reversing drives, serpentine drives, conveying systems, packaging machinery, printing equipment, textile machinery, and factory automation .

Q: What is the warranty?
A: 3 Years – quality assured.
