C-flex Bearing Co Inc

What C-flex Bearing Co Inc does

C-Flex Bearing Co., Inc. is a privately held precision manufacturer founded in 1988 in Frankfort, New York, employing 1-10 people. The company designs and produces frictionless pivot bearings and flexible shaft couplings based on a proprietary flexure technology in which flat spring internal structures permit limited-angle rotary motion without contacting parts, lubrication, or backlash. Standard products include 10, 20, and 30 series pivot bearings in sizes A through J offered in single cantilever and double end configurations, alongside lattice, servo, and superplastic flexible couplings in 48+ standard sizes, plus clamp bushings and bespoke custom designs for loads above 5,000 lbs.

The company's customer base spans aerospace and defense (missile guidance, rocket thrust vectoring, laser designators, drone gimbals), space (NASA NEOWISE, Vera C. Rubin Observatory), semiconductor manufacturing equipment, medical devices, and broadcast/cinema stabilization. Materials include 400 series stainless steel standard with optional titanium and inconel for extreme temperature or vacuum applications; operating range is -100°F to 375°F continuous, up to 450°F intermittent. The bearings offer indefinite cycle life when operated within rated specifications and a minimum 30 million cycle life expectancy below the indefinite life curve.

C-Flex operates a sales-led, distributor-amplified go-to-market model. Products are sold through three US distributors (Stock Drive Products in New York, Norman Equipment in Illinois, Ondrives US Corp in New York) and international sales representatives in Germany (GAD Elektronik), the United Kingdom (Automation International), and Singapore (EM Fusion), supplemented by direct inquiry-based sales via phone and email. Pricing is quote-based and not publicly disclosed. Custom engineering, accelerated life cycle testing, and flat flexure designs for solenoid applications extend the revenue mix beyond catalog products. The company is privately held with no disclosed funding rounds or institutional investors.
