Overview
The Gates 8MGT-1440-21 is a Poly Chain GT Carbon synchronous belt engineered for high-torque, low-speed industrial drives. This belt features a curvilinear tooth profile, polyurethane construction, and carbon reinforcement, delivering the durability and accuracy required in machine tool, conveyor, and compact automation systems. When combined with Gates Poly Chain GT2 sprockets, this provides a lightweight, long-lasting, maintenance-free system that’s more than a match for roller chain.
Key Features
- Patented carbon fiber tensile cord provides increased horsepower rating for greater power density and compactness, with increased flexibility allowing backside idlers
- Gates patented curvilinear tooth profile provides high shear strength and improved load carrying capacity
- Durable high-temperature polyurethane construction resists chemicals, oil, pollutants, and abrasion
- Nylon tooth facing reduces friction and eliminates the need for lubrication
- Robust carbon tensile cord combines minimal stretch with extraordinary strength while absorbing shock and surge loads
- Quiet, maintenance-free operation without re-tensioning or oil lubrication
