Automatic belt tensioners heavy duty

The Dayco Gold Label "NO SLACK" Heavy Duty Tensioner has been designed to meet or exceed Original Equipment requirements. Specifically, this translates into a heavy-duty cast aluminium body for extra strength and durability; heavier pulley arms to withstand greater torque load; a patented "flat spring" design specifically engineered to meet the higher torque and power pulses exerted by today's diesel engines; and rugged pulleys with two lifetime lubricated bearings to deliver long-lasting dependable service. In addition, virtually all Dayco Gold Label Heavy Duty Tensioners feature "externally dampened" designs using a wave spring and a metal ring with bonded rubber surface to act as a "radial shock absorber" for the tensioer arm.
