About the company
Ringfeder Power Transmission USA Corp, a foreign-owned manufacturer of mechanical power transmission equipment and springs based in Bolton, Connecticut, operates primarily as a prime contractor (79% of recent awards) and secondarily as a subcontractor on defense manufacturing programs, with work concentrated in production of ordnance and ground combat systems components for the Department of the Army and the Defense Logistics Agency.
Ringfeder's customer base is heavily concentrated in Army acquisition. The top five customer entities account for 71% of recent awards by count, dominated by the Department of the Army Acquisition Support Center PEO Ground Combat Systems (3 awards) and the Defense Logistics Agency (3 awards), with additional work from the Department of the Army, TACOM Life Cycle Management Command, and the Army Corps of Engineers. Dollar concentration is thin — the combined potential value across all 14 awards in the source data is $36,000, but the vendor has obligated $1.6 million across those same awards, indicating substantial delivered value relative to the nominal contract ceilings. The Defense Logistics Agency Land and Maritime and Troop Support Construction and Equipment accounts account for $26,000 and $10,000 in stated potential value respectively.
Ringfeder's capability footprint aligns with its manufacturing base. The top NAICS categories are Small Arms, Ordnance, and Ordnance Accessories Manufacturing (4 awards), Spring Manufacturing heavy and light gauge combined (3 awards), and Mechanical Power Transmission Equipment Manufacturing (2 awards). Recent subcontract work exemplifies the ordnance focus: three delivery orders from Northrop Grumman Systems Corporation, dated May, July, and August 2025, cover production orders for the XM813 cannon incorporated into the Stryker 30mm Engineering Change Proposal program. Ringfeder places task orders under an Indefinite Delivery Contract (W56HZV20D0108) with 3 task orders recorded in the source data.
The vendor's award activity in the source data is sparse and episodic — one award in 2004, two in 2005, isolated awards in 2007 and 2010, and a concentration of three awards in 2025. The corporate structure includes a subsidiary, The Carlyle Johnson Machine Co, LLC, also foreign-owned and a manufacturer of goods. Ringfeder does not hold a parent federal contract vehicle; its prime work operates through individual task orders and standalone contracts issued by Army acquisition and DLA supply-chain vehicles.
