WINertia™ AV-Air Vent Aluminum Dead Shaft Idler
Eliminate wrinkles and improve web stability with the WINertia™ AV-Air Vent Dead Shaft Idler. Its patented design removes entrapped air 7.5x faster, delivering smoother web handling, consistent tension, and superior material control at high speeds.
Key Benefits:
- Removes entrapped air 7.5x faster for optimized web handling
- Lightweight aluminum construction reduces inertia for precise tension control
- Minimizes web wrinkles, drag, and material distortion
- Reduces downtime, web waste, and long-term maintenance costs
- Short lead times available — ships in as little as 5 days
The WINertia™ AV-Air Vent Aluminum Dead Shaft Idler by Maxcess is engineered to dramatically improve web handling by removing entrapped air 7.5 times faster than traditional idler rollers. This advanced airflow technology minimizes web wrinkles, improves tracking, and maintains stable tension — even at high production speeds. Lightweight aluminum construction ensures low inertia, energy efficiency, and superior tension control, making it ideal for applications such as converting, laminating, flexible packaging, and high-speed printing.
Engineered for High-Speed, Precision Web Handling
With patented AV-Air Vent technology, WINertia™ idlers provide consistent, smooth web control by eliminating air entrapment during high-speed operation. The unique vent design reduces web distortion, enhances tension consistency, and extends product life through reduced wear. Use the Componex WINertia Calculator to easily configure your shaft size, length, and bearings.
