STAFFORD MANUFACTURING CORP

What STAFFORD MANUFACTURING CORP does

Stafford Manufacturing Corp., founded in 1975 and headquartered at 256 Andover Street, Wilmington, Massachusetts, is a privately held precision manufacturer of shaft collars, rigid shaft couplings, flanged devices, and motion control components used to position, hold, and transmit torque on shafts. The company offers more than 4,000 standard products across imperial (1/16"–6") and metric (8mm–80mm) bores, in materials including steel, stainless steel, aluminum, brass, and engineered plastics, manufactured in an ISO 9001:2015-certified facility. Its proprietary sub-brands — SPARC™, Accu-Flange™, Accu-Clamp™, Accu-Mount™, Python™, Staff-Lok™, SlipKnot™, Grip & Go™, and Flip-Lok™ — address use cases ranging from one-piece and two-piece clamp collars to quick-adjust, hinge, threaded, flanged, set-screw, weldable, square/hex bore, and inch-metric conversion configurations, with Heavy Duty variants delivering roughly 2–3x the holding power of standard parts. SPARC™, in particular, pairs 3D-printed inserts with machined master collars to deliver working prototypes within hours.

Revenue is generated through one-time unit sales of standard SKUs (e.g., stainless steel Accu-Flange collars priced $56–$113 and steel variants $69–$216, with volume discounts) and quote-based custom and modified products including standard part modifications, machined components, sheet metal components, and fully custom builds. Distribution combines an owned e-commerce storefront (with CAD downloads, an online Rigid Shaft Coupling Configurator, and free 2nd-day air shipping on US orders over $50), an authorized distributor network, an independent sales representative network, and an inside sales team handling RFQs and custom inquiries. End markets are horizontal and diversified across animatronics and themed entertainment, warehouse automation (conveyors, AGVs, robots, sorting), robotics, food processing, packaging, hospital and rehabilitation equipment, and general industrial machinery, with no named enterprise customers and no disclosed revenue figure.

Broad incumbents

• McMaster-Carr: Dominant industrial MRO supplier with an enormous catalog of shaft collars, rigid couplings, and mechanical components; competes for the same broad-base SMB and engineer-driven demand with same-day fulfillment.
• MISUMI: Global industrial catalog distributor with configurable shaft collars, couplings, and motion components sold direct-to-engineer with CAD downloads and rapid delivery, directly competing with Stafford's e-commerce and configurator offering.
• Boston Gear (Altra Motion): Established broad-line industrial power transmission supplier offering shaft collars, couplings, gears, and drives under the Altra Motion portfolio; competes with Stafford in couplings and collars while serving a much wider product catalog.
• Martin Sprocket & Gear: Large incumbent industrial manufacturer offering shaft collars and couplings as part of a much broader power transmission and material handling catalog; serves similar industrial customers but with a far larger footprint and brand portfolio.
• Lovejoy (by Timken): Established power transmission brand (now part of Timken) producing rigid and flexible shaft couplings used in industrial, automation, and processing applications; a broader incumbent competitor in the coupling category.

Regional players

• KHK (Kohara Gear Industry): Japanese manufacturer of gears, couplings, and shaft collars serving global automation customers via catalog distribution; a comparable catalog-driven precision components supplier with strong presence in Asia.

Direct peers

• Climax Metal Products: Direct peer producing shaft collars, set screw collars, and rigid couplings in steel, stainless steel, and aluminum with custom machining services, overlapping substantially with Stafford's standard product line.
• Ruland Manufacturing: Closest direct peer: a U.S. precision manufacturer of shaft collars, rigid couplings, and motion control components with overlapping product categories (one-piece/two-piece clamp collars, rigid couplings), serving very similar robotics, automation, and industrial OEM customers.
• Helical Products Company: Manufacturer of flexible and rigid couplings, shaft collars, and machined motion control components, competing directly in coupling-based power transmission for precision industrial and aerospace customers.
• Ondrives.US: U.S. precision manufacturer of shaft collars, rigid couplings, and worm gear clamps targeting OEM and automation customers with comparable customization and small-batch machining capabilities.
