Diamoflex Conveyor Belting Information

Belt Widths

DiamoFlex belts are available in standard widths up to 1400 mm. Other widths are available on request.

Belt Type

This figure indicates the nominal tensile strength in N/mm. Other types available on request

Carcass Type

The carcass consists of 3 plies of 100% synthetic polyester-nylon (EP) fabric, making it impervious to moisture with low elongation and high tensile strength. The plies are bonded to extra-thick interply layers of tough, resilient rubber for maximum impact resistance


Elongation at break in warp
Elongation at T1*
* Elongation at T1 would occur if applied stress is equivalent to 10% of the nominal tensile strength.

Cover Quality

DiamoFlex is available in all DIAMOND cover qualities

Cover qualities:

Normal quality       DA, DS, DE Abrasion resistant
Special quality        HA, HS, HE Heat resistant
Special quality        OR1, OR2 Oil resistant

Pulley Diameters

Pulley diameters are determined by carcass thickness and tensile strength.

Weights and Thickness

To determine the total belt thickness add the sum of the cover thickness to the carcass thickness

Impact Resistance

One of the main advantages of the DiamoFlex conveyor belt is “sandwich” construction of the carcass, resulting in higher energy absorption capability and greater impact resistance than regular four or five-ply belts of the same tensile strength.

This feature is especially advantageous at the loading point as coarse material impacts the belt from great height.

In order to illustrate the high impact resistance of a DiamoFlex, here is a test under simulated service conditions to compare with a four or five-ply conveyor belting of the same tensile strength.

Test Procedure

A 10 kg weight falls from a height of 2.5 m onto a

pre-stretched length of belting. The belting is supported by an idler on the spot where the weight drops onto the belt. After each impact, the remaining tensile strength in the belt is measured as a percentage of the original tensile strength.
