Quotations are built against the specific BOM position — quantity, traceability expectation, and whether a repair exchange or a new-in-box unit is acceptable all factor into the RFQ response, because EOL stock is lot-specific and the available quantity varies with each pull.","metaTitle":"Siemens 1FK7044-4CH71-1QA0 Servo Motor, 7.26 kg","metaDescription":"1FK7044-4CH71-1QA0 Siemens 1FK7 high-dynamic synchronous servo motor, listed at 7.26 kg.
