Subec PUR Integral Hardfoam Sheaves are precision-casted from high-density polyurethane integral rigid foam, combining a lightweight core with a tough, impact‑resistant outer skin. This construction provides wear resistance while keeping rotational inertia low, making them suitable for high‑speed and dynamic applications. Available in diameter 500 and D 800 with Radius or Flat grooves, Subec PUR Integral Hardfoam Sheaves deliver reliable performance with minimal maintenance in industrial environments.
