These ribs provide a larger surface area for contact, which allows for improved traction and reduces slip compared to traditional V-belts. The TB2 designation typically refers to a specific design variation or dimension suitable for certain pulley systems. These belts are utilized in a wide range of applications, from automotive engines to industrial machinery, where they transfer power efficiently and effectively.
