Automatic Belt Tensioners Heavy Duty

Dayco Heavy Duty Automatic Belt Tensioner designed for heavy duty diesel engine accessory drive applications

As the major supplier to heavy duty original equipment manufacturers, Dayco’s Heavy Duty Tensioners are guaranteed to be engineered and manufactured to the strictest design specification. The heavy-duty cast aluminum body and pulley arms translate into extra strength and durability. Dayco’s Heavy Duty Tensioner features a patented “flat spring” design that’s engineered to handle the higher torque and power pulses exerted by today’s diesel engines. Rugged pulleys with double lifetime lubricated bearings deliver long lasting, dependable service. In addition, virtually all Dayco Heavy Duty Tensioners feature “extremely damped” designs using a wave spring and a metal ring with a bonded rubber surface to act as a “radial shock absorber” for the tensioner arm.
