The Benz NBS Abrader meets and exceeds specifications, described in ASTM D-1630, for abrasion resistance of vulcanized rubber or other compounds. This abrasion machine consists of a 6" diameter drum; three arms, pivoted at one end, with a mass suspended from the other end; three dial thickness gauges with 0.001" graduation; an internal blower and vacuum; a digital cycle counter; and a controlled abrasive (40 grit, No. 1-1/2 garnet paper; 6" in width)
  • clean, uncontaminated specimens - internal blower and vacuum
  • precise cycle measurement - digital display counter
  • simple to use - ready-to-test within minutes
  • increase test volume - three samples tested at once
Benz services and calibrates every instrument we sell, as well as most major manufacturers' models.
