Full definition
Traditional V-belt design with a woven fabric cover (jacket) wrapping the entire cross-section, protecting the rubber compound from oil, abrasion, and environmental damage. More economical than raw-edge belts but delivers 5-15% lower efficiency due to reduced sidewall friction. The fabric layer prevents the rubber from directly contacting the groove, slightly reducing grip. Per ISO 4184, DIN 2215. Still widely used in light-duty, non-critical, and replacement applications. Standard profiles: Z, A, B, C, D, E (classical) and SPZ, SPA, SPB, SPC (metric). Available in standard or antistatic versions. Suitable for general HVAC, agriculture, and light industrial drives.
