The unique chemical and mechanical characteristics of ELATECH® belts together with the possibility of a wide variety of backings in
different materials make ELATECH® belts ideal for all conveying applications where synchronization is required. The engineer desi-
gner has unlimited possibilities to make unique designs.
Minimum pulley diameter
The raccomanded pulley diameter shown for each type of backing, are valid for application with speed up to 1m/s and temperature
of 20° C. When smaller pulley diameter are needed please consult with Elatech technical department.
Drive with reverse bending
Elatech polyurethane timing belts are suitable for drives with reverse bending. Tension should be adjusted, depending on backing
hardeness.
Temperature
Hot items may be conveyed when a correct backing is selected. In such a case, ensure that the belt toothed structure does not over
come 80° C.
The special polyamide fabric backings allow a reduction of the
friction coefficient and when applied on teeth, decrease noise in
high speed drives. They are very useful in applications with sli-
ding surfaces or product accumulation.
PAZ: Polyamide backing on tooth side
Reduces coefficient of friction and allows a smother
tooth engagement.
PAR: Polyamide backing on back side
Reduces coefficient of friction.
