Description

Material
Neoprene with polyester tensile cord.
Note
Endless V-belt acc. to DIN 7753 (narrow V-belts). Electrically conductive acc. to ISO 1813. The V-belts are of equal length (from 1000 mm).

Narrow V-belts are more efficient than classic V-belts.

The V-belts have limited oil resistance. Avoid continuous contact with mineral oils and grease as these will reduce the service life.
Temperature range
-55 °C to +70 °C.
Service life is reduced if the V-belts are exposed to continuous temperatures above +60 °C.
Assembly
The belts need to be tensioned after installation. Re-tensioning is required after an initial run time of 15 - 20 minutes.

If, by a drive with several belts, one belt requires changing, then the full belt set should be replaced.
