Full definition
Synonym for V-belt, named after the trapezoidal (wedge-shaped) cross-section that provides the characteristic friction-multiplying wedge action in the pulley groove. In Latin America and European ISO/DIN documentation, "correa trapezoidal" or "Keilriemen" is more common than "V-belt," which predominates in American (RMA/ARPM) catalogs. Technically identical products; the naming difference is purely regional. Per ISO 4184 (metric: SPZ/SPA/SPB/SPC) and RMA IP-20 (classic: A/B/C/D/E). When ordering, always specify profile, length designation (Li, Ld, La, or Lw), and whether wrapped or raw-edge.
