Pulleys and Belts SIT HI-PERFORMANCE Pd® Plus / HPPD PLUS

SIT Hi-Performance Pd® Plus synchronous belts provide a reliable, economical, and trouble-free alternative to transmit power. With reduced drive weight and cost when compared to classic V-belts. Lubrication and tensioning devices are not required thus creating a cleaner, maintenance free synchronous drive. SIT Hi-Performance Pd® Plus belts have been designed for performances exceeding the traditional limitation of the first generation of HTD belt drives.
