The document contains several tables providing information for the transmission of power using pulleys and belts. Table 1 lists common machines and their recommended service factors. Table 2 recommends belt section sizes for normal motor speeds and powers. Table 3 lists the recommended diameter ranges for drive pulleys depending on the belt section. Tables 4A, 4B and 4C provide belt power transmission data for different belt sections and diameters at various line speeds.
