The number of flanges is given as either 0, 1 or 2. Should a pulley with hub, have only one flange, then it should be designated as follows: Flange on hub side (diagram left) - 1a Flange on the side opposite to the hub (diagram right) - 1g

PULLEY SELECTION SUGGESTIONS
• Pulley diameter should not be smaller than the belt's width.
• If centre distance is more than 8 times the diameter of smaller pulley, both the pulleys should be flanged.
• Never crimp fibre glass cord belts. Crimping will cause damage to fibres, resulting in premature belt failure.
• Pulley diameter should not be smaller than the belt's width.
• If centre distance is more than 8 times the diameter of smaller pulley, both the pulleys should be flanged.
