Barden Corporation

What Barden Corporation does

Barden Corporation, legally HQW Aerospace (UK) Ltd, is a UK-based manufacturer of super precision ball bearings established in 1947 and headquartered in Plymouth, Devon. The company designs and produces bearings to ABEC 7/ISO P4 tolerances as a minimum, with an advanced materials portfolio spanning ceramic hybrid bearings (steel rings with ceramic balls), high-nitrogen steel AMS5898, and silver-plated steel and bronze cages. Engineered product families include deep groove, angular contact, spindle (3mm–180mm OD), full complement, hybrid, thin/extra thin section bearings, plus bespoke custom designs supported by MESYS dynamic analysis and finite element modelling. Application expertise extends across aerospace and defence (aircraft starter generators rated to 10,000–30,000 rpm, airframe systems), medical systems (imaging, surgical and diagnostic), vacuum technology, space and satellites, nuclear control-rod actuation, oil and gas drill heads, autosport, and high-speed industrial spindles.

The firm operates a vertically integrated B2B model: bearings are engineered and manufactured in Plymouth, where over 300 skilled jobs were retained following the June 2019 divestiture from the Schaeffler Group to German strategic buyer HQW Precision GmbH. Commercial reach combines direct enterprise sales from UK headquarters with regional sales offices in France (opened November 2021) and India (opened December 2020), a global network of authorised distributors, and co-marketing with parent HQW Precision under the 'Partners in Precision' umbrella. Barden markets through industry trade shows (EMO Milano, Space Comm Expo UK), downloadable technical catalogues and direct enquiry handling. Geographic distribution is restricted to Europe, India and explicitly excludes the USA and the rest of the Americas per the company's published terms.

Revenue is generated through hardware sales of bearings on a quote-based B2B pricing model tailored to OEM specifications and volumes; no public pricing or revenue disclosure is available. ISO 9001 governs quality management at the Plymouth facility, and nuclear, aerospace and defence products carry additional traceability and process certification. The company does not disclose revenue, has no recorded funding rounds (being a wholly-owned subsidiary of HQW Precision GmbH), and leadership comprises Managing Director Damian Dunne alongside applications engineering and regional sales staff.
