Pacamor Kubar Bearings

What Pacamor Kubar Bearings does

Pacamor Kubar Bearings (PKB), the operating trade name of S/N Precision Enterprises Inc., is a privately held, veteran-owned small business that manufactures high-precision miniature and specialty ball bearings. From a single facility at 145 Jordan Road in the Rensselaer Technology Park, Troy, NY, the company produces 440C stainless steel bearings in multiple configurations — straight, flanged, angular contact, full-complement, thin-section (Thinex), metric, and duplex-paired — alongside ceramic-hybrid variants using silicon-nitride (Si3N4) balls. Supporting the catalog, PKB sells bearing components including retainers/cages (crown, ribbon, phenolic, Meldin, Delrin, Rulon, PEEK, Torlon, AlumBronze), closure types (shields, Teflon, rubber, Viton seals), and ball options (steel, TiC-coated, ceramic/silicon-nitride). The largest metric outside diameter the company can produce is 28.57mm, anchoring it firmly in the instrument-grade miniature segment. Custom and specialty bearings with non-standard bores, widths, and internal geometry extend the catalog into engineered-to-order work.

The commercial focus is aerospace and defense. PKB supplies bearings for weapons optics, guided missiles, and military platforms, and for private, commercial, and general aviation applications; the company's short description additionally references space vehicles, satellites, and flow-control units. Quality credentials are central to its positioning: ISO9001:2015 and AS9100D aerospace certifications, DoD Cage Code 14927, and SAM registration for federal procurement, alongside a US/Canada Joint Certification dated November 2025. The go-to-market is direct B2B — quote-based sales conducted over phone (518-283-8002) and email ([email protected]) with a website catalog for top-of-funnel awareness — supported by organic social presence on LinkedIn, Facebook, X/Twitter, Instagram, and YouTube. There are no disclosed distributors, resellers, or channel partners.

The business model is one-time hardware sales of standard catalog products and custom-engineered bearing solutions to aerospace, defense, and aviation buyers, with potential recurring orders from established customer relationships. Pricing is quote-based; no public list pricing exists. Headcount is in the 11–50 range (per firmographic data), the company is privately held with no disclosed parent, subsidiaries, institutional investors, M&A, or funding rounds, and it is described as actively operating with all bearings manufactured at its Troy facility.
