Bemsco

What Bemsco does

Bemsco Inc. is a privately held precision manufacturer founded in 1967 and headquartered at 1193 South 400 West, Salt Lake City, Utah. The company produces complex machined components and electro-mechanical assemblies for the aerospace and commercial industries, with documented programs spanning the Blackhawk UH-60 helicopter (Main Landing Gear), Boeing KC-135/707 (Carriage Assembly Center Flap), the B-52 bomber (Main Landing Gear components), and the Erickson S-64 Aircrane. Assemblies range in size from two-component builds to functional assemblies comprising roughly three hundred components, with all flight-critical items subjected to 100% Pressure and Cycle Testing in an in-house FOD Free Clean Room.

The company operates a single-site manufacturing facility built around predominantly Mazak CNC equipment, including a five-axis Mazak VTC-800/30-SR full contouring machining center, multiple four-axis Mazak Nexus vertical machining centers, three-axis CNC mills, four-axis CNC lathes, and high-speed horizontal machining centers with 20-second automatic pallet changers. Quality assurance is performed on Zeiss/DCC Coordinate Measuring Machines, and engineering is supported by Solidworks 3D solid modeling under an approved Digital Product Definition (DPD) Plan. The Quality Management System is certified to AS9100 Rev D and ISO 9001, and the company is ITAR registered, qualifying it for U.S. defense supply-chain participation.

Bemsco runs a direct, sales-led go-to-market with no e-commerce or self-serve channel; customers request quotes via [email protected] for projects ranging from single components to full assemblies. Revenue is generated through project-based manufacturing contracts with aerospace OEMs and defense contractors, with pricing structured per quote. The company maintains approved integrations with REDARS (electronic drawing access), Exostar (secure document exchange), and FTP for digital data interchange, supporting program management from design data through machining, assembly, environmental testing, and finishing (prime and paint).

Core offering

Bemsco manufactures complex machined components and electro-mechanical assemblies for the aerospace and commercial industries. The company produces landing gear parts, structural fittings, carriage assemblies, and similar precision components using CNC milling, turning, and assembly operations. Programs range from single components to complex functional assemblies comprising up to roughly 300 components, with 100% pressure and cycle testing performed in an in-house FOD Free Clean Room.

Product overview

Bemsco is a precision manufacturer of complex machined components and electro-mechanical assemblies for the aerospace and commercial industries. The company offers a unified manufacturing platform with five interconnected core capabilities: Assemblies (electro-mechanical assemblies ranging from 2 to 300+ components including landing gear, carriage assemblies, and structural components), Milling (CNC precision milling with 5-axis and 4-axis capabilities), Turning (CNC turning with multi-axis lathes), Electrical (electrical and connector assemblies), and Solid Modeling (3D CAD model creation using Solidworks for manufacturing process support). The company utilizes predominantly Mazak CNC equipment and Zeiss CMM technology, and maintains AS9100 and ISO 9001 quality certifications. Services extend from single-component light milling to complex functional assemblies requiring heat treat, welding, environmental testing, and finishing.

Broad incumbents

• TransDigm Group: TransDigm designs, produces, and markets proprietary aerospace components and systems. While more proprietary and higher-margin than Bemsco, it represents the strategic destination profile for a precision aerospace components supplier scaling into proprietary content.
• Howmet Aerospace: Howmet is a large-cap aerospace components manufacturer producing engine and airframe parts. Operates in the same precision aerospace components category but at vastly larger scale and broader program coverage than Bemsco's narrow Tier-2/-3 footprint.
• Curtiss-Wright Corporation: Curtiss-Wright provides engineered products, systems, and services for defense, commercial and industrial markets including aerospace components. A broad incumbent whose defense/aerospace segment overlaps with Bemsco's structural and precision components business.
• Precision Castparts (Berkshire Hathaway): Precision Castparts (now part of Berkshire Hathaway) is a major Tier-1 manufacturer of complex aerospace components including machined airframe and engine parts. Serves as a larger-scale incumbent reference point for Bemsco's product category.

Direct peers

• Magellan Aerospace: Magellan manufactures complex aerospace assemblies and machined components for civil and military aircraft programs. Like Bemsco, it specializes in tight-tolerance machined parts and assemblies supplied into established aerospace platforms and MRO cycles.
• Ducommun Incorporated: Ducommun is a US-based Tier 2/3 aerospace manufacturer of structural components, assemblies, and engineered solutions serving Boeing, Lockheed Martin, Sikorsky, and Raytheon. It is the closest publicly traded analog to Bemsco's profile of precision machined and assembled aerospace parts delivered direct to primes.
• Senior plc: Senior is an aerospace components specialist producing high-precision fluid conveyance, structural, and mechanism assemblies. Comparable in being a Tier-2 supplier of complex engineered aerospace parts and assemblies to major OEMs.
• HEICO Corporation: HEICO's aerospace segment manufactures FAA-approved parts and components used in aircraft — a directly parallel operating model of building bespoke, qualified aerospace parts supplied into the same aftermarket and OEM value chains Bemsco serves.
• Triumph Group: Triumph designs, engineers, manufactures, repairs, and overhauls aerospace structures, components, and assemblies. Direct overlap with Bemsco in supplying structural/aerospace machined components and assemblies, though at considerably larger scale and program breadth.

Emerging players

• Stellex Engineering & Manufacturing: Stellex (subsidiary of Stealth suk) is a precision machining and assemblies supplier focused on aerospace and defense. A more direct size-comparable competitor pursuing similar tier-2/3 contract machining and assembly work as Bemsco.
