Description
Upgrade to the Gates Poly Chain® GT™ Carbon™ Belt System
Give yourself a competitive advantage by designing with the Gates Poly Chain™ GT™ Carbon™ drive system. Engineered as a superior alternative to traditional roller chains, this belt utilizes a patented carbon fiber tensile cord to provide increased horsepower ratings, exceptional power density, and a highly compact footprint. The result is a lightweight, long-lasting, and completely maintenance-free power transmission solution.
Key Features & Benefits
- Extreme Durability: Polyurethane construction heavily resists chemicals, oil, pollutants, and general abrasion.
- Carbon Tensile Cord: Delivers extraordinary strength, maximum load-carrying capacity, and minimal stretch.
- Optimized Tooth Profile: The patented curvilinear design ensures high shear strength and significant noise reduction.
- Maintenance-Free: Nylon tooth facing eliminates friction, meaning zero lubrication or re-tensioning is required.
- Direct Replacement: Offers equivalent capacity to roller chains in the exact same width but operates much quieter.
- Wash-Down Ready: Enables easy, rust-free wash-downs when paired with Gates® Stainless Steel hardware.
Application Advantages You Can Count On
- 5% Energy savings over standard V-belts
- 30% Higher power ratings than previous constructions
- 99% Efficiency maintained for the life of the drive
- 400% Greater capacity than traditional HTD belts
Industrial Markets & Applications
Perfectly suited for all industrial markets, this belt is the ultimate choice for replacing high-maintenance roller chain drives. The belt's narrow width significantly minimizes reducer overhung loads. When paired with Poly Chain® GT® 2 sprockets, the left-justified hubs seamlessly accommodate short shaft lengths.
⚠ Important Compatibility Warning
Always utilize Taper-Lock® type Poly Chain® GT® 2 Sprockets when designing a new Poly Chain® GT® Carbon™ belt drive system. The use of non-Gates manufactured sprockets is strongly discouraged. Gates sprockets are specifically manufactured and tested to support the full capabilities of this belt; performance cannot be guaranteed if alternative sprockets are used.
