By actively enhancing friction between the belt and pulleys, these belts ensure efficient power transmission, even under heavy loads. Mitsuboshi's expertise is evident in our use of advanced materials, coatings, and pulley modifications, all of which contribute to higher grip and improved efficiency. These belts are particularly well-suited for demanding industrial applications where reliable torque transfer is crucial for performance and longevity.  # Products - All - Wrapped - Raw Edge Cogged - Banded - Flat - V-ribbed - Variable Speed - Polyurethane - Rope V-belt ##### Classical ![Conventional](https://www.mblusa.com/hs-fs/hubfs/Belts%20(photos,%20graphics,%20profiles,%20etc.)/Belt%20Photos/Conventional.jpg?width=575&height=300&name=Conventional.jpg)**Classical** V-belts are economical, highly versatile, and are extensively used in a wide range of applications.
