V-belts are named for their distinctive “V” shape, which allows for a more effective grip on pulleys, reducing slippage and increasing efficiency. They are commonly made from rubber, fabric, and synthetic materials, which contribute to their strength, flexibility, and durability. As machinery operates, V-belts endure considerable tension and exposure to a variety of environmental factors, making their reliability crucial for industrial and commercial functions.
