BSF

What BSF does

BSF, Incorporated is a US-based designer and manufacturer of custom electro-mechanical and hydraulic flange-to-flange connection products, founded in 1975 and headquartered in Vandalia, Ohio. The company builds fabricated steel pump/motor adaptors (C-Face, IEC/Metric, D-Flange, Vertical Mount, Bolt On Base, Cast Aluminum, foot mounts, mounting plates, shaft extensions) from ASTM A53 Grade B ERW pipe and ASTM Grade A36 steel plate, machined to precision tolerances of 0.003 inches TIR. BSF operates as a vertically integrated custom manufacturer with in-house CAD/Solidworks design, CNC machining, and custom engineering services that deliver line drawings within 24 hours and standard adaptors in 10-12 working days. The product line is complemented by value-added distribution of shaft couplings from Magnaloy (one of the largest US stocking distributors), Lovejoy, Guardian, KTR, and Hayes, including patented products such as the Hayes Hex-Flx coupling.

The company monetizes through one-time sales of custom-built adaptors (priced per specification), per-unit sales of distributed couplings at markup, and bundled custom engineering services included with quotes. All sales are conducted direct-to-customer with no distributor intermediation, through the company website (including the BSF Adaptor Configurator for instant 3-5 minute quotes with drawings), toll-free and international phone lines, and email, with global drop-ship fulfillment. The customer base spans fluid power, oil & gas, industrial hydraulics, motion control, and broader industrial manufacturing, with named enterprise accounts including Bosch Rexroth, Colfax Engineered Systems, Sunsource, Womack Systems, and National Petroleum Oilfield Products.

BSF is privately held by President Kathryn Keel (with the company since 1980), employs 20+ people, has held ISO 9001:2015 certification continuously since 1998, and operates with no disclosed outside funding, subsidiaries, or M&A activity. Distribution and engineering partnerships with five coupling brands and a single in-house patent (US 7,645,089 B2, held via the Hayes distribution relationship) anchor the broader product offering beyond proprietary adaptors.

Revenue model

1. Custom Adaptor Manufacturing: Design and manufacture of custom-built-to-order pump motor adaptors, bell housings, foot mounts, and related components. Products are fabricated to customer specifications with unique part numbers. Revenue is generated through one-time product sales with pricing based on complexity, materials, and specifications.
2. Coupling Distribution: Distribution of shaft couplings from partner manufacturers including Magnaloy, Lovejoy, Guardian, KTR, and Hayes. BSF acts as a stocking distributor for Magnaloy couplings (one of the largest in the US) and distributes other brands. Revenue from markups on distributed products.
3. Custom Engineering Services: Engineering design services included with adaptor quotes - design team works with customers to develop custom solutions with engineered drawings. Customers receive quotes and line drawings within 24 hours of request.

Core offering

BSF designs, engineers, and manufactures custom-built fabricated steel pump motor adaptors, bell housings, foot mounts, mounting plates, and shaft extensions that connect hydraulic pumps to electric motors across non-standard flange combinations. In addition to its own manufactured line, BSF distributes shaft couplings from leading brands (Magnaloy, Lovejoy, Guardian, KTR, and Hayes) to serve as a one-source supplier for motor-to-pump connection components.

Product overview

BSF Inc. is a premier supplier of electro-mechanical and hydraulic flange-to-flange connection products, founded in 1975. The company manufactures a comprehensive portfolio of pump motor adaptors (including C-Face, IEC/Metric, Vertical Mount, Bolt On Base, and Cast Aluminum variants), distributes shaft couplings from partner brands (Magnaloy, Lovejoy, Guardian, KTR, and Hayes), and provides foot mounts, sound reduction products, mounting plates, and shaft extensions. The core product line centers on connecting motors to pumps and hydraulic equipment, complemented by an online Adaptor Configurator tool and custom engineered solutions service. BSF operates as both a manufacturer of proprietary steel and aluminum adaptors and a distributor of branded coupling products from established partners.

Functional benefit

Products and services

• C-Face Adaptors (Steel) Fabricated steel adaptors that mount a NEMA C-face electric motor to a hydraulic pump flange, enabling flexible motor-to-pump pairing for industrial hydraulic systems.
• IEC/Metric and D-Flange Adaptors Adaptors that connect IEC/Metric frame electric motors to hydraulic pumps with D-flange mounts, supporting international motor standards.
• Vertical Mount Adaptors Custom-designed adaptors for vertical motor-to-pump mounting configurations where horizontal space is constrained.
• Bolt On Base Adaptors Adaptors with an integrated bolt-on base that simplifies mounting of the motor-pump assembly to a frame or skid.
• Hayes Engine Housing Bell housings that enclose and align the coupling between a motor and pump, providing protection and precise shaft alignment.
• Cast Aluminum Mounts Cast aluminum motor-to-pump mounting components offering lighter-weight alternatives to fabricated steel adaptors.
• Sound Reduction Adaptors Adaptors with integrated sound-absorbing barriers designed for noise-sensitive installations such as agricultural sprayers and other applications where hydraulic noise must be minimized.
• Magnaloy Shaft Coupling Magnaloy-brand shaft couplings distributed by BSF to connect motor and pump shafts with misalignment tolerance.
• Lovejoy Jaw Type Coupling

Expansion highlights4 records

Broad incumbents

• Regal Rexnord: Regal Rexnord is a large diversified power transmission and motion control manufacturer whose couplings, gear drives, and bearing products overlap with BSF's adaptor and coupling offerings. Operates as a broad portfolio incumbent rather than a niche specialist.
• Flowserve Corporation: Flowserve is a global leader in pumps, valves, and seals for industrial flow control. Its pump products are among the end devices that BSF's custom adaptors connect to motors and power transmission systems, making it an adjacent incumbent in BSF's served ecosystem.
• Baldor (ABB Motion): Baldor (now ABB) is a major manufacturer of industrial electric motors and mechanical power transmission products including C-Face motors that BSF's adaptors mate to. Overlaps with BSF at the motor-to-pump interface but at vastly larger scale and broader portfolio.
• TB Wood's (by Altra Industrial Motion): TB Wood's, part of Altra Industrial Motion, supplies couplings, belted drives, and power transmission products competing with BSF's distributed coupling lines (especially Lovejoy). Serves the same industrial pump/motor customer base at much larger scale.

Emerging players

• Bailey International: Bailey International manufactures hydraulic adapters, manifolds, and cylinder components for mobile and industrial hydraulics. Comparable to BSF in custom-fabricated hydraulic adapter space, though with broader focus on cylinders and manifolds rather than pump/motor adaptors.
• Air-Way Manufacturing: Air-Way Manufacturing produces hydraulic fittings, adapters, and fluid power components serving mobile and industrial equipment markets. Overlaps with BSF in custom metal hydraulic/pneumatic adapter fabrication for OEM and aftermarket customers.

Direct peers

• Magnaloy: Magnaloy manufactures shaft couplings and pump/motor mounts — products that BSF both distributes (one of the largest US stocking distributors) and competes with as a fabricator of pump motor adaptors. Closest comparable in coupling technology and pump mount design.
• KTR Systems: KTR manufactures flexible shaft couplings (Bowex, Rotex) that BSF distributes to US customers. Both serve industrial fluid power and power transmission customers needing precision coupling solutions for pump/motor assemblies.
• Guardian Coupling: Guardian manufactures curved-jaw and gear-style shaft couplings that BSF distributes. The two companies compete in the same flexible coupling product category and share many of the same pump/motor and motion control end customers.
• Lovejoy (by Timken): Lovejoy is a leading manufacturer of jaw-type shaft couplings and power transmission components. BSF is an authorized Lovejoy distributor, and both companies sell into the same industrial pump/motor coupling market with overlapping end customers.
