ADR

What ADR does

ADR is a French industrial manufacturer established in 1925 in Thomery, near Fontainebleau, specializing in bespoke high-precision ball bearings and integrated rotating systems. Its core offering comprises custom-engineered bearings (thin-section, high-speed, high-temperature, and corrosive-environment variants), integrated ball bearings, servomotors and motorised bearings (SVM80, SVM140), and electromechanical sub-systems including the G3AC composite carbon 3-axis gimbal. Manufacturing is anchored by an in-house precision grinding workshop and a 1,200 m² clean room facility, enabling production to aerospace-grade tolerances for defence, space, aeronautics, energy (including nuclear fusion), medical, and industrial customers.

The company operates on a project-based, make-to-order revenue model: prospective customers submit technical specifications via a 'Definition of Needs' form, ADR engineers a custom solution, and pricing is delivered as a bespoke quote under multi-year contracts. Go-to-market combines direct sales coverage in France and China with exclusive country-specific agents in India, Israel, Italy, South Africa, South Korea, and Ukraine — driving an export ratio of approximately 60% of turnover. The product portfolio is certified to ISO 9001 and EN 9100 (aerospace) standards, and ADR holds a 91/100 French Gender Equality Index.

ADR has been a wholly-owned subsidiary of the French diversified technology group ALCEN since 2004, providing access to technical synergies across ALCEN's health, fusion, systems, and defence verticals while ADR remains operationally independent at its Thomery site. The company employs 101-250 people and is currently celebrating its 100th anniversary with an Assembly workshop renovation and expansion completed in 2025.
