If top cover and pulley cover are balanced (i.e., 3/16 in.x3/16 in. or 5mm x 5mm) or less than 1/16 in. (2mm) differential (i.e., 3/16 in.x 5/32 in. or 4mm x 3mm), add 6 in. (150mm) to the
minimum belt width. 6 in. (150mm) narrower widths are possible if the belt is broken in for an extended period of time fully loaded. Consult your Sales Representative. Additional break-in
time is required when the belt has been stored prior to insulation in ambient temperatures of less than 50°F (10°C).
Above tables are based on top cover gauge equal or greater than the bottom (pulley) cover gauge.
