Description Technical Specs
 

Premium quality is what you need in an A19 belt. Find your system's solutions in our large stock at USA Roller Chain. Every 4L210 V-belt is made with a cotton-poly blend for the cover, high-strength polyester for the cord and combination rubber for the main body. In fact, the A19 V-belt uses a quality mixture of styrene-butadiene rubber and natural rubber in order to maintain its shape. The 21-inch V-belt also offers flexibility for those applications with looser specifications or vibrations. At USA Roller Chain, we can make nearly any application more productive with our high-quality products.

This 21-inch drive belt comes with a 40-degree angle that helps it maintain its position in your pulley system. Stretch the belt over your assemblies and watch it come alive. USA Roller Chain stands behind every product that we sell. It's time to see your profits rise with V-belts that last.

  • Cover - High-quality cotton/ polyester blend

Note: We also have Cogged V-Belts which include longer operational life, cooler running, and around a 2% higher efficiency raring than a standard v-belt.
