What Is a Rubber Round Belt?

Rubber round belt is made from natural or synthetic rubber compounds.

Key features:

• Softer and more flexible
• Good grip performance
• Lower cost
• Heat resistance

Typical Applications:

• Light-duty machinery
• Traditional equipment
• Low-speed transmission

PU vs Rubber Round Belt: Main Differences
