Overview
The Gates 28008MGT20 PowerGrip GT2 is a high-performance synchronous timing belt engineered for precision positioning and torque transmission in industrial automation and motion control systems. With 350 teeth and a 110.24-inch pitch length, this belt combines Gates’ proprietary curvilinear tooth profile with dual-sided tooth geometry to deliver superior load carrying capacity and consistent timing accuracy.
Key Features
- Double Load Capacity: Double loading capacity over equivalent Twin Powerâ„¢ PowerGripâ„¢ HTDâ„¢, enabling more compact and lighter drive designs.
- Dual-Sided Teeth Design: Dual-sided teeth to provide equal load carrying capacity on either belt surface, suitable for contra-rotating drives.
- Neoprene Construction: Made of neoprene for resistance to dirt, grease, oil, and moisture, ideal for demanding industrial environments.
- Fiberglass Reinforcement: Fiberglass tensile cords for strength, durability, and resistance to elongation and a nylon tooth facing for quieter operation and resistance to wear.
- Low-Noise Operation: Running at low noise compared to chain drives and older belt systems.
- Wide Temperature Range: Temperature range: -30°C to +100°C (-22°F to +212°F).
