Polyurethane V Belts
Polyurethane V belts are durable and flexible power transmission belts made from thermoplastic polyurethane (TPU). Their V-shaped cross-section fits into matching V-groove pulleys. These urethane drive belts transfer power and motion between rotating shafts in machinery. They provide superior flexibility, strength, and resistance to abrasion and chemicals, ensuring long-lasting performance.
