# SAM #80NSSC27944391Q NASA sole-source requirement for stainless 50-ton machine screw jacks and blast-door hardware **Buyer:** NASA Shared Services Center **Posted:** October 26, 2026 **Respond By:** October 28, 2026 **Identifier:** 80NSSC27944391Q **NAICS:** 332999, 333923 NASA Langley needs specialized stainless-steel screw-jack hardware to restore operation of a 40-ton blast door at its scramjet test facility. - **Requirement:** A set of lifting screw jacks and associated couplers, protective shields, and limit switches. The notice also describes the item as a stainless jack screw; quantities and part numbers are not stated. - **Key specifications:** Each jack must provide 50-ton vertical capacity, stainless-steel construction, and at least 150 inches of installed travel. The assembly requires clevis ends, a 32:1 direct-drive coupling, protective bearing boots, and compatibility with the facility’s selected motor system; jack input-shaft and limit-switch positions vary by jack. - **Sole-source approach:** NASA intends a sole-source award to Motion Industries, Inc. The supporting documents recommend MiMotion and describe its site evaluation and specialized design proposal as the basis for a sole-source negotiation. The documents do not clarify the relationship between Motion Industries and MiMotion. - **Vendor rationale and support:** MiMotion was the only vendor identified as willing to conduct a site visit and evaluate unusual operating and drag conditions. Its Chesapeake office committed to commissioning and post-commissioning technical support. - **Schedule and response:** Estimated delivery lead time is 16 weeks. Interested organizations may submit capability statements by October 28, 2026, at 7:00 a.m. Central Standard Time; quotes are not requested or evaluated. Re-solicitation could delay repairs to the non-operational access door by weeks or months and increase costs. ### Description
