Conveyor Belt Designations Information

Belt Width

Belt widths are stated in millimeters (mm), (also in meters and preferred widths) and are international standard.

Standard Widths in mm:

300       400      500      650      800      1000

1200    1400    1600    1800    2000     2200

Other belt widths are available on request.

Permitted width tolerances according to international standards

Belt width 300 - 500 mm + 5 mm.

Belt width 650 or wider + 1 %

Number of Plies

The number of plies in the carcass indicates the figure for the nominal tensile strength.

Standard values for the nominal tensile strength of each individual ply:

63     80     100     125     160     200

250   315    400    500    630    (N/mm)

The nominal strength of the belt carcass is indicated by the strength of each ply multiplied by the number of plies rounded off to the nearest nominal tensile strength. The number of plies is left out in belt types, where the carcass is determined by the type description; for example, two plies and three plies.

Cover Thickness

The thickness of top and bottom cover is stated in millimeters (mm).

Permitted tolerances of the cover thickness according to international standards:

Belt thickness up to and including 4 mm: - 0.2 mm.

Belt thickness over 4 mm: - 5%

Belt Thickness

The total belt thickness is the sum of top and bottom covers plus carcass thickness.

Permitted tolerances of the total belt thickness according to international standards:

Belt thickness up to and including 10 mm: + 1 mm

Belt thickness over 10 mm: + 10%

Belt Length

The belt length is usually stated in meters (m), either open or endless.

An open belt length means the circumference of an installation plus the extra length for splicing. The endless belt length is the inner circumference of the spliced belt.
