Eagle PD


Welcome to the exciting world of Goodyear Eagle PD, a unique and revolutionary concept in synchronous belts and sprockets.

Your first look at an Eagle PD Belt and Sprocket will tell you that this product is quite different than anything offered in the timing belt market today.

Outstanding Benefits:

  • Noise reduction
  • Reduced maintenance
  • Energy efficiency
  • Reduced vibration
  • Reduced downtime
  • Increased horsepower
  • Reduced drive width and weight

Quiet, Precise Power Transmission:

  • Hot ( Helical Offset Tooth) design of Eagle PD provides for a continuous rolling tooth engagement that helps reduce noise by up to 17 – 19 db vs. typical round tooth positive drive belts.
  • Eagle PD helps safety engineers meet OSHA noise standards
  • Silent partnership between belt and sprocket also provides for a reduction in drive vibration which means improved precision on finished parts.

Efficiency in power transmission drives reduces wasted energy dollars.

  • Eagle PD is the perfect compliment for today’s high efficiency rated motors. Because v-belt and chain drives quickly lose initial tension, they typically run in the lower portion of their efficiency range. Eagle PD will continually run at about 98% efficiency.
  • Eagle PD is especially effective in
    • High energy consuming drives
    • Drives that run continuously
    • Drives that inflate energy consumption during peak periods

Less maintenance compared to V-belts and roller chain

  • Typically 20% of the drives cause 80% of the maintenance problems. Eagle PD requires less maintenance which means a reduction in costly downtime.
  • Eagle PD requires no lubrication – a constant concern with chain drives.
  • Chain and V-Belt drives require constant retensioning – Eagle PD, once properly installed, never requires retensioning.
Advantages Over V-belts Advantages Over Chain
  • Reduced downtime and  maintenance costs
  • No stretch
  • Eliminates tensioning devices
  • Lower belt tension/ reduced bearing loads
  • High Mechanical efficiency
  • No slippage
  • Reduced noise
  • Reduced downtime and maintenance costs
  • No stretch
  • Eliminates lubrication system
  • Not affected by corrosion
  • Wide speed range
  • Longer service life
  • Greater precision

 Eagle PD™ Belt Construction Features/Benefits

Hibrex® rubber compound

  • Formulated to increase tooth rigidity and load carrying capacity.
  • Chemically stable to resist effects of oil, coolants heat, ozone and other chemicals

Flexten® Tensile Members

  • Excellent dimensional strength and high impact strength.
  • Optimal resistance to flex fatigue, elongation and shock loads while operating in high torque conditions.

Hibrex® Impregnated Plioguard® Fabric Facing

  • Reduces tooth engagement friction
  • Provides wear and abrasion protection

Eagle PD™ Sprocket Construction Features/Benefits

  • Designed to insure maximum service life
  • Statically balanced and surface tested for corrosion resistance
  • Sprockets and belts designed to run with minimum resistance between them leading to long, troublefree service life
  • Engineered for use with industry standard QD bushings

Color Coded Part Numbering System

Eagle PD™ color spectrum system incorporates a color coded part numbering system of belts and sprockets of the same size

  • Provides emergency down-time product selection flexibility
  • Faster part identification
  • Easier drive recommendations with simplified design process
  • Assurance that drive components match
  • Available in 8mm pitch (yellow, white) and 14mm pitch (blue, green, orange, and red)

Eagle PD Part Number Nomenclature

Notice that the first sprocket is a finished bore sprocket (there is no bushing designation). Finished bore sprockets are supplied with set screws and a key way. The second sprocket has a machine hub compatible with an "E" QD Bushing.
