Belt drives. Grooved pulleys for narrow V-belts. Groove sections 9N/J, 15N/J and 25N/J (effective system) Ingestion-build-225643 Lorry-mounted variable-reach trucks1 Scope This International Standard specifies the principal characteristics of grooved pulleys (for groove sections 9N J, 15N J and 25N J) intended to take both single and joined narrow V belts for industrial power transmission drives. Some background information on the series of effective diameters is given in annex A. NOTE The effective width of a groove is regarded as the basic dimension of standardization in the effective system for grooves and
