SKF PHGSPZ637 — V-belt (wedge belt)
SKF · Bearings & Power Transmission · V-Belts
SKF PHGSPZ637 v-belt (wedge belt). Classical (A, B, C, D, E) or narrow-section (SPZ, SPA, SPB, SPC / 3V, 5V, 8V) endless V-belt for friction-drive power transmission. Polyester or aramid tension cord in an oil-and-heat-resistant chloroprene body. Dimensioned to ISO 4184 / RMA IP-20 classical and ISO 4184 / RMA IP-22 narrow. Set-matched belts identified by a common numeric drive-number code so multi-belt drives share tension. Designation follows the SKF alphanumeric identification convention where the numeric block encodes the boundary plan and the suffix declares execution options (material, sealing, cage, precision, clearance, lubricant). Genuine SKF supply carries the SKF logo etch or moulded mark and hologram-authenticated packaging.
