Dayco ® No Slack™ spanroll/spanroll

Dayco's reputation for top performance tensioning and tensioning pulleys is the result of advanced automotive technology used in material research, design engineering and production of our pulleys. In addition to our spun steel pulleys, Dayco also supplies specially formulated glass - filled polymers to ensure a high-strength, wear-resistant plastic pulley designed to replace serpentine and V - string idler and tensioning pulleys.

The use of state-of-the-art three-dimensional computer-aided design (CAD) and finite element analysis (FEA) guarantees the optimal design and maximum structural integrity for both plastic and steel pulleys. Pulleys with smoother surfaces and tighter dimensional tolerances translate into less vibration and thus a longer belt life. High temperature lubricated bearings and seals ensure peak performance, which is the most critical element of a pulley's life.
