RESISTANCE TO SEPARATION
Due
to the special chemical components in the rubber covering, oil resistant
belts are less adhesive than our standard belts.

ELONGATION UNDER STANDARD LOAD
To determine tension course of a belt, the technical conditions of the installation must be taken into account. As a guideline, the DIN 22.102/89 norm establishes the following values:
