Manufacturers Assocation (CEMA) recom-mends that wing pulleys not be used on belts traveling over 2,25 meters per second (450 ft/min). A better choice than the conventional winged tail pulley is a spiral-wrapped tail pulley (Figure 6.5). These pulleys have an additional steel strip wrapped in a spiral around the pulley circumference. The steel
