In addition to Dayco spun steel pulleys, Dayco also provides specially formulated glass-filled polymers to insure a high strength, wear-resistant plastic pulley designed to replace serpentine and V-belt idler and tensioner pulleys. The Dayco No Slack idler and tensioner pulleys are designed to replace serpentine and V-belt idler and tensioner 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 therefore longer belt life. Lubricated bearings and high temperature seals assure peak performance, the most critical element of a pulley's service life.

Since 1905, Dayco® has been a leader in the automotive parts manufacturing industry. During the early 1900s, Dayco was the first and only company manufacturing the airless tire. By the 1920s, the company had a robust tire manufacturing process in Dayton, Ohio for cars, large trucks and buses. From its founding to today, the company has followed its primary business strategy to anticipate and satisfy all the needs and requirements of its customers by providing innovative, quality, and durable products. Today its wide product line includes belts, tensioners, pulleys and hydraulics equipment for the automotive, construction, trucking, ATV, agricultural, snowmobile, and industrial markets.
