Eliminate conventional belt issues in spiral applications with our friction-driven solution.
A remarkable retrofit option for capstan drive systems, the Intralox Series 2900 Spiral 1.6 belt features a modular plastic design that ensures easy maintenance and cleanability. Its robust outside edge protects against premature fatigue failures, while its modular construction enables simple, quick repairs.
- Performs within a continuous temperature range of -50°F to 200°F (-46°C to 93°C)
- Minimum turn radius of 1.6 times belt width
- Open area aids product freezing and cooling

- This belt has pinch points. See the Safety section in the Intralox Conveyor Belting Installation, Maintenance & Troubleshooting Manual for more information.
- Contact Intralox for precise belt measurements and stock status before designing equipment or ordering a belt.
- Belt openings pass straight through the belt to simplify cleaning.
- Relatively uniform open area across the width of the belt aids product freezing and cooling.
- Robust edge feature adds strength to the outside edge of the belt.
- Cage-friendly inside edge and frame-friendly outside edge
- Enhanced beam stiffness.
- Each belt material has a default rod material. Other rod materials are available. Intralox can help identify the best belt and rod material combination for your application.
- Detailed material information is provided in Product Line.
- Eliminates product contamination from metal-wear debris.
- Enables simple, quick repairs and changeovers.
- Designed for friction drive, capstan drive spiral applications with a minimum turn radius of 1.6 times the belt width (measured from the inside edge).
- Contact Intralox for a spiral analysis and the preferred run direction on spiral applications.
- Minimum sprocket indent from the inside belt edge and from the outside belt edge can vary. Contact Intralox Customer Service to determine exact placement.
