Description
# Polyflex™ Belts
High Modulus Polyurethane compound resists fatigue, wear, ozone and most environmental conditions. It also improves adhesion to the tensile cords.
## BIG POWER FOR SMALL SPACES.
Polyflex™ Belts were specially designed to transmit maximum power for a variety of small precision v-belt drive applications. The belt’s ribs are designed to reduce bending stress on miniaturized drive components, while their 60° angle construction provides added support for even load distribution. This enable their use in high-performance, precision applications, accommodating shaft speeds in excess of 10,000 rpm.
## Features and Benefits
– The 60° angle results in better support of the tensile section, and provides a more even load distribution.
– Design freedom and space savings which are not possible with conventional rubber construction belts.
– Ribbed backing provides greater lateral stability and relieves bending stress.
– Polyurethane is extremely resistant to heat, chemicals and oil.
– Low maintenance cost as belt needs less re-tensioning.
– Improves adhesion to the tensile cords.
– Long belt life on compact drives.
## A MATERIAL DIFFERENCE.
Every Gates power transmission product is made at the leading edge of material science and manufacturing processes. Gates® Polyflex™ Belts are precision cast, using our own proprietary process that forms the belt in a seamless, single layer. Their HDPE compound construction provides material properties that combine strength, flexibility, and high temperature tolerance. The result is a precision application belt that provides exceptional load-carrying capacity, application versatility, and durability.
