VC6X520 ( MB-520 ) V Belts are replacement belts. Major applications include household electric equipment, labor-saving equipment, chemical equipment, office machinery, optical machines, compact machine tools, electric tools.

MB-520 ( VC6X520 ) Polyurethane MB Belts consist of two components, including polyurethane body and tensile cord (Polyester or Aramid Kevlar available upon request).
More specifically, polyurethane body is extremely wear and fatigue resistant and highly flexible. Tensile Cords give high flexibility. So bonding of both components provides high performance.
