SST plastic pulleys are commonly used in power transmission, fitness equipment and motor transfer applications, among other industries. These pulleys are well-suited for high-speed belt idlers found in the lawn and garden industry along with conveyors. SST pulleys are made with high-quality materials that minimize noise and vibration. All caps for pulleys are ultrasonic welded to ensure quality assemblies. Our plastic pulleys are manufactured using a conductive plastic construction, along with either precision ABEC-1 bearings and/or bushings. Various sizes are available immediately from inventory to minimize downtime.
