"S" and "D" refers respectively to Single and Double Leather Belts; while “Ply" refers to Rubber Belting.

Rim speed should not exceed 5000 feet per minute for standard pulleys. To find rim speed, multiply diameter of pulley in feet by 3.1416 and again by the revolutions of the pulley.

Pulleys should be located sufficient distance apart to insure a slight sag in slack side of belt.

To insure long life of belt, care should be taken that shafting and pulleys are properly aligned and that there is sufficient clearance to outside objects.
