Fey laminar rings offer a particularly robust and dimensionally stable type of metallic sealing. The characteristic laminar structure creates defined sealing gaps that reliably protect against lubricant loss, dust, particles, and thermal loads. The different versions—single and multi-wound, open, closed, or combined with retaining functions—enable their use in a wide variety of machine and drive systems.
view laminar ringsSince 1946, Fey has been developing and manufacturing high-precision laminar sealing and retaining rings for demanding applications in drive technology, mechanical engineering, automotive and energy. Our speciality is metallic sealing systems that function reliably even under high speeds, temperatures and loads.
With more than 16,800 variants and deep engineering know-how, we offer solutions that are tailored exactly to the respective application – based on standards or individually developed. Fey stands for precision, technical safety and maximum reliability – Made in Germany.

Quality management
Guarantees stable processes, documented testing procedures and consistently high product quality. For customers, this means: reliable deliveries, reproducible results and minimal error rates.
Automotive standard
The world’s leading quality standard in the automotive industry. It demands the highest levels of precision, traceability and process reliability. Fey therefore meets all the requirements for OEM and Tier 1 supply chains.
Environmental management
Certifies a resource-efficient, sustainable and environmentally responsible production system. For customers, this means a reduced environmental impact and compliance with modern ESG requirements.
Fey stands for sealing technology that maintains consistent performance even under demanding conditions. Precise metal geometries, controlled preload and high dimensional stability ensure that the sealing effect is maintained even in the face of vibration, high speeds or fluctuating temperatures.
Thanks to the wide range of variants and carefully selected material options, FEY rings can be tailored precisely to the specific application. This reduces friction, extends the service life of bearing points and enhances the process and operational reliability of entire systems.
Fey sealing elements therefore offer not only sealing in the traditional sense, but also clear technical added value – wherever reliability and precision are crucial.
Fey laminar rings are used wherever classic sealing or retaining elements reach their limits. They work reliably under high speeds, temperatures, vibrations and tight installation space requirements – in gearboxes, bearings, drives, exhaust systems and precision machinery. Thanks to their metallic design, defined preload and flexible variety of variants, they offer a durable, low-maintenance solution for the most demanding industrial applications.
view applicationsOur laminar and sealing elements support key industries in making their systems safer, more efficient and more durable. Whether in mobility, power generation, manufacturing technology or heavy mechanical engineering – we supply components that can be integrated exactly into existing systems and perform crucial functions. For every industry, we develop custom-fit solutions that simplify development processes, reduce maintenance costs and increase operational reliability. In this way, our products make a measurable contribution to the performance of modern industrial applications.
