Dayco idler/tensioner pulleys are built with smoother surfaces and tighter dimensional tolerances, which translates to less vibration and longer belt life. In addition to stamped, forged steel and powdered metal pulleys, Dayco also designs ultra-strong plastic pulleys with specially formulated glass-filled polymers that resist wear and tear. Premium lubricated ball bearings and double high temperature seals ensure peak bearing performance, the most critical element of a pulley’s service life.

Product Features:

• Designed for the majority of automotive vehicle applications on the road today
• High-quality materials help resist wear and improve belt life
• Features premium lubricated bearings to extend service life
• Meets or exceeds OE quality

The Dayco automatic belt tensioner features Dayco’s original, patented flat spring design to provide less operating range variation. It reduces the risk of premature accessory bearing failure due to high tension and lessens the risk of belt noise and slippage – or poor performance caused by low tension. A PTFE string wound within the spring resists abrasion and dampens noise. Dayco’s tensioner is also designed with a heavy-duty cast aluminum spring case and arm, which helps resist cracking and fatigue and offers additional strength, lessening the risk of distortion. Additional premium thermoplastic rubber spring slot plugs and rubber O-ring seals help keep contaminants out and zinc coated mounting bolts resist rust.
