Lifecycle read on this 1FK7-CT frame
The 1FK7060-2AF7.-.... is flagged EOL/HOT on the Siemens Servo Motors line, so the OEM channel is in last-time-buy territory and most active quotes route through independent surplus and broker stock rather than factory-direct. For a maintenance buyer that means the BOM line is still fillable today, but the clock on fresh-factory supply is the binding constraint — not the spec sheet.
What the rating line says about fit
On paper the 1FK7060-2AF7.-.... is a SIMOTICS S 1FK7-CT compact synchronous servo: 1.5 kW rated power on a 600 VDC bus link, 6 Nm continuous torque at the 100 K thermal class, 3000 rpm rated speed, naturally cooled. That combination — 600 VDC drive bus, M0 = 6 Nm, NN = 3000 rpm — sizes it for mid-range point-to-point axes, small indexing tables, and feeder/auxiliary drives on a SINAMICS S120 line-up where a water-cooled or forced-ventilated frame would be overkill. Naturally cooled is the spec that actually drives mechanical integration: no fan cowl, no blower cable, and the motor can be mounted in sealed cabinets or next to a gearbox without provisioning a cooling-air path. The trade-off is continuous-torque derating in a fully enclosed panel — the 6 Nm figure holds at 100 K winding temperature rise only when the surrounding air path actually lets the housing shed heat.
Sourcing posture for a hot part
EOL/HOT changes the procurement flow: the right move is to specify against the BOM, confirm current availability at quote time, and lock the variant suffix (the trailing -.... on this code covers shaft, holding brake, and encoder options) before release. Independent distribution carries 1FK7060-2AF7.-.... against an RFQ with lot-traceable stock; the cross to a still-active 1FK7 successor or a 1FK2-frame replacement needs a real cross-reference, not a guess at the spec table.
