The new high torque Panther Plus outperforms chain and gears as well as conventional synchronous belts. Strong ULTRA-CORD is a non-aramid fiber tensile member that delivers strength and dimensional stability. It doesn?t retain moisture and won?t shrink. It shrugs off shock loads. Resilient the uniquely designed parabolic profile teeth are made of ABLE, an advanced polymer compound which increases both the strength and abrasion resistance of the teeth. Energy Efficient The smooth, quiet performance of Panther Plus absorbs shock loads and softens surges. Operating efficiency is 98 - 99% through a wide range of operating speeds. Panther Power with Panther Plus, you get high torque power transmission with less wear, less noise and less maintenance from a less expensive and more compact drive.</p>
