The IDEF International Defence Industry Fair, taking place at the Istanbul Expo Center from 22–27 July 2025, stands out as one of the most significant global events where the heart of defense technologies beats. As Akar Rulman, we will be at Booth B21 in Hall 1, showcasing our high-precision bearing technologies and innovative solutions tailored for the defense industry to sector professionals.
Every component used in defense projects must minimize margin of error, withstand harsh environmental conditions, and reduce the risk of malfunction to nearly zero. The high-precision bearing series designed and supplied by Akar Rulman deliver reliable performance across a wide range of applications—from military land vehicles to smart munition systems, from naval platforms to radar systems. Our procurement processes, compliant with ISO 9001, AS9100, and MIL-STD-810 standards, ensure the level of quality and traceability meticulously required by the defense sector.
At IDEF 2025, we will present our product range and capabilities specifically designed for industry needs, including special alloy steels, thin-section bearings, and aerospace control bearings. These bearings maintain minimal heat buildup at high speeds thanks to their low friction coefficient, ensuring uninterrupted performance even during extended missions. In addition, our coatings that withstand harsh atmospheric and terrain conditions significantly extend bearing life, even under aggressive environmental factors such as salt air and humidity.
The FEM analyses and test scenarios conducted at Akar Rulman’s R&D center support all phases—from prototyping to mass production—with scientific data. This allows users to rely not only on quality certifications but also on real field data, ensuring maximum continuity in their projects.
During your visit to IDEF, you can meet with our expert engineering team for one-on-one consultations to explore tailored solutions, and get detailed information about our sample and demo programs. At Booth B21 in Hall 1, we will also hold product presentation sessions covering bearing assembly, lubrication, material selection, life testing, and cost advantages.
In the defense industry—where a reliable supply chain is of critical importance—Akar Rulman provides uninterrupted support to your projects with robust supply capabilities and a flexible logistics infrastructure. Our fast delivery, inventory management, and custom packaging solutions ensure your operational continuity throughout the procurement process.
Visit us at Booth B21 at the Istanbul Expo Center between 22–27 July to discover how we contribute to defense projects and the national defense industry with high-precision bearing technologies. We look forward to shaping the future of defense and custom manufacturing solutions together!

What is IDEF – 17th International Defence Industry Fair?
IDEF 2025, taking place for the 17th time at the Istanbul Expo Center from 22–27 July 2025, will once again open its doors as Eurasia’s largest gathering in the field of defense technologies. The event is hosted by the Republic of Türkiye Ministry of National Defense, supported by the Presidency of Defence Industries, and organized by KFA Fuarcılık Inc. under the management and responsibility of the Turkish Armed Forces Foundation.
Held biennially, IDEF brings together a wide range of products under one roof—from land, sea, air, and space defense solutions to border security, cyber defense, and logistics support systems. The 16th edition in 2023 was visited by 94,198 professionals from 107 countries and featured 1,461 companies showcasing their latest products and technologies—figures that signal the potential for new records in the 2025 edition.
Throughout IDEF 2025, delegation meetings, B2B sessions, signing ceremonies, and live product demonstrations are planned. Leading defense manufacturers, procurement authorities, and decision-makers will gather in Istanbul to explore opportunities for modernization projects, joint production agreements, and technology transfer initiatives.
The fair serves as an unmissable platform for all defense professionals seeking to follow the latest trends, build strategic partnerships, and expand their export channels. Registration is carried out through the official IDEF website; early registrants can benefit from the appointment system to schedule meetings in advance with leading companies.
As IDEF 2025 puts the present and future of the defense industry in focus, the event will highlight innovation, sustainability, and the vision of domestic and national production as its core themes. By securing your place at this major gathering, you’ll have the opportunity to witness first-hand the developments shaping the future of the global defense industry.
Our High-Precision Bearing Technologies
Every component used in the defense industry requires the flawless integration of parts manufactured with tolerances as precise as a thousandth of a millimeter. At Akar Rulman, our high-precision bearing series are engineered to meet these critical requirements using advanced production techniques such as special alloy steels, ceramic ball combinations, and vacuum melting. Our thin-film coatings, which provide a low coefficient of friction, minimize heat generation at high speeds, while our solid lubricant-reinforced bearing housings eliminate the risk of lubrication loss even during long-duration operations.
Our process control systems, compliant with ISO 9001 and AS9100 quality standards, test the geometric accuracy of each bearing using laser interferometers—maintaining axial and radial clearance values within a ±0.5 µm range. Corrosion-resistant passivation layers provide full protection against salt, sand, and high humidity in marine and desert environments, while our MIL-STD-810 compliant vibration and shock tests ensure absolute reliability for vehicle and platform integrations.
Our smart bearings, which can be integrated with real-time monitoring sensors, report temperature and vibration data instantly—laying the foundation for predictive maintenance strategies and significantly reducing maintenance costs. In short, Akar Rulman’s high-precision technologies combine durability, efficiency, and safety in a single solution, elevating the performance of your defense projects into the future.
