RW 630/4 6+2 (In Stock)

4-ply belt, thickness 12.4 mm, 630 N/mm, for heavy duty applications

4-ply belt, thickness 12.4 mm, 630 N/mm, for heavy duty applications
General Features:

  • Increased adhesion between layer package and covering layers - Homogeneous covering layers (scrapers work well)

  • Entire belt produced and tested in the Narviflex Lab so that it meets the highest class according to DIN 22102 type W

  • DIN 22102 type W tires are the most wear-resistant (wear value guaranteed < 90 mm3). Usually the tires that are on the market in the Benelux only have a very moderate wear value of < 150 mm3 (Type Y). In this case, the lower the wear value, the less volume loss during the abrasion test according to DIN standard and the less material that can be abraded during the test, the more wear-resistant the tire!
