Goodyear Engineered Products dual synchronous belts have
precision teeth on both sides. This allows the design of more
sophisticated, more efficient, and more compact drives where a
single belt is needed to provide accurate timing from either side,
rotation direction changes, or both.
Since a Dual Hi-Performance Pd or Dual Positive Drive belt can
replace two or more single-sided synchronous belts, less space is
needed. This reduction in space means smaller sprockets can be
used, bringing the weight and component cost of the drive system
down considerably, contributing to a more efficient drive system.

Dual Hi-Performance Pd belts, with their unique round tooth
profile, drop into corresponding HTD sprockets. They were
designed to minimize interference between belt and sprocket
during mesh, providing greater horsepower capacity without
slippage or speed variation. By designing the tooth to disperse
critical stresses and create a positive engagement with the
sprocket, belt performance is improved along with assuring longer
belt life.

The tension-carrying member in Dual HPPD and Dual Positive
Drive belts is twisted from multiple strands of fiberglass cord which
are high in tensile strength, flex life, and resistance to elongation.

Our dual synchronous belts are made with specialized compound
technology designed to resist damaging environmental factors that
can shorten belt life. This compound technology has excellent
oil, heat, ozone, and abrasion resistance, increasing durability and
preserving belt flexibility leading to extended belt life.
