SKF PHG639-3M-6 — Timing belt (synchronous drive belt)
SKF · Bearings & Power Transmission · Timing Belts
SKF PHG639-3M-6 timing belt (synchronous drive belt). Synchronous drive belt engaging matched-pitch sprockets to transmit torque with a fixed shaft-to-shaft speed ratio and no slip. Trapezoidal (MXL / XL / L / H / XH / XXH), curvilinear (HTD / STD / RPP), and modified curvilinear (Poly Chain GT) tooth profiles. Tension member glass-fibre or aramid cord; body chloroprene or hydrogenated nitrile rubber (HNBR). Standards ISO 5296, ISO 13050, DIN 7721, RMA IP-24. 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.
