Dual Tooth
Double Sided Timing Belts

Our dual tooth double sided timing belts solve a specific integration challenge: equipment where one shaft uses arc-tooth (AT) precision pulleys and another uses classical trapezoidal (T-series) pulleys, but a single continuous belt loop is still the most efficient way to link them. Rather than forcing one profile onto both faces, this belt molds a genuinely different tooth geometry on each side, engineered so both mesh correctly with their respective pulley standard.

Material & Construction

Each face is molded with its own distinct tooth geometry — typically an AT precision profile on one face and a classical T-series profile on the other — using a dual-cavity molding process that cures both tooth forms simultaneously around a shared, centered tension cord layer. Tension member selection (steel or fiberglass) is chosen to satisfy the higher-load face's requirements while remaining compatible with both engagement geometries.

Design & Performance

Because the two tooth profiles differ in geometry and pitch, engineering the pitch relationship between faces requires careful design so that both sides remain synchronized to the same base belt length — our design team calculates this pitch relationship for each specific pulley combination rather than offering a generic catalog part. This makes the product inherently semi-custom, engineered around your specific pair of pulley standards.

Manufacturing Excellence

Dual-cavity tooling is manufactured specifically for each customer's profile combination and verified with both tooth geometries measured independently against their respective pitch standards (AT per DIN 7721, T-series per DIN 7721) before belts are released for shipment.

Customization & Flexibility

Because each project typically involves a unique pairing of tooth profiles, this line is engineered to order based on your specific pulley combination — AT/T-series, T-series/HTD, or other combinations. Our team will confirm feasibility and pitch compatibility before quoting.

Applications Across Industries

Our dual tooth double sided timing belts are deployed in:

• Retrofit Equipment Upgrades – linking new precision pulleys to legacy classical pulleys.
• Mixed-Generation Machinery – equipment combining old and new drive standards.
• Custom Machine Building – OEMs integrating components from different pulley standards.
• Specialty Automation – purpose-built machines with mixed-profile requirements.
• Laboratory Equipment Integration – combining precision and standard-duty drive stages.
• Prototype & R&D Equipment – flexible integration during development phases.

When your drive train has to bridge two different pulley standards on one loop, an engineered dual-tooth belt is often simpler and more reliable than redesigning the drive around a single profile. Two profiles, one integrated solution.
