SKF PHG4PJ550 — Ribbed drive belt (Poly-V)
SKF · Bearings & Power Transmission · Ribbed Belts
SKF PHG4PJ550 ribbed drive belt (poly-v). Multi-rib longitudinally-grooved friction belt (Poly-V) combining the shock absorption of a V-belt with the flexibility of a flat belt. Rib profiles PH, PJ, PK, PL and PM per ISO 9982. Suitable for accessory drives on marine diesel engines, HVAC blowers, industrial fans and pumps. 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.
