Overview
The Gates 28008MGT20 PowerGrip GT2 timing belt is a high-performance synchronous belt engineered for applications requiring precise timing and reliable power transmission. With dual-sided teeth configuration, this belt delivers 100% load capacity from either side, enabling contra-rotating drives and flexible system configurations. The modified curvilinear tooth profile—Gates’ proprietary GT tooth design—ensures superior engagement with matching pulleys and reduced backlash compared to trapezoidal belt systems.
Key Features
- Dual-sided tooth design — equal load capacity on both belt surfaces for bidirectional drive applications
- Non-slip positive drive — fiberglass tensile cords and nylon tooth facing eliminate slip in timing-critical systems
- Neoprene body — resists moisture and contaminants, extending service life in harsh environments
- Low-noise operation — running at low noise due to nylon-faced teeth and modified tooth profile
- Extended temperature range — rated -30°C to +100°C (-22°F to +212°F) for industrial environments
- Higher torque capacity — double loading capacity over equivalent Twin Power PowerGrip HTD

Typical Applications
The Gates 28008MGT20 PowerGrip GT2 suits precision motion control systems across industrial automation, manufacturing equipment, and power transmission drives. Ideal for applications such as 3D printers where precise synchronization is critical. Eliminates lubrication and re-tensioning reduce maintenance and labor as compared to roller chain drives. Commonly used in:
- Industrial automation and robotics
- Packaging and labeling machinery
- Textile and printing equipment
- Precision positioning systems
- Contra-rotating drive systems
- Low-speed, high-torque applications
