Precision Slewing Drives for Defense and Surveillance Systems
TGB Group designs and manufactures high-performance motion components – including slewing rings, slew drives, rotary actuators, linear guides, and precision bearings – engineered for dual-use applications in both civil and defense sectors.
These components provide controlled rotation and precise linear motion for systems operating under demanding conditions. Technical engineers and defense procurement specialists rely on TGB’s solutions for their reliability, performance, and customization in harsh environments.
Engineered for Dual-Use Applications
TGB’s motion solutions are truly dual-use: they excel in civilian industries like renewable energy and heavy machinery, and in advanced defense systems.
The same slewing rings used in wind turbines or cranes are trusted in military platforms like tanks, missile launchers, and radar stations, enabling 360° rotation and accurate target tracking.
This cross-sector approach means components proven in industrial environments are deployed confidently in defense equipment — always built to withstand harsh conditions and deliver smooth, precise motion.
Trusted in Critical Defense Systems
Defense applications demand more than just performance — they require proven reliability. TGB’s rotary components, adapted from heavy-duty civil use, offer the strength, longevity, and precision needed in:
Weapon stations
Sensor platforms
Radar and tracking systems
Mobile missile launchers
Naval turrets and mounts
Unmanned ground or aerial vehicles
Across land, sea, and air, TGB motion solutions deliver repeatable precision and stable performance under fire, shock, or vibration.
Built to Perform in Harsh Environments
TGB designs every component to perform in extreme conditions: temperature shifts, dust, humidity, shock loads, and continuous duty cycles.
Slew drives come sealed and protected, ensuring internal gears and bearings stay clean and functional in the most punishing settings.
All motion components are built with tight tolerances, low backlash, and long service life, making them ideal for radars, turrets, and launcher systems that cannot fail in the field.
Complete Range of Motion Products
TGB’s portfolio covers both rotary and linear motion, designed for integration in demanding systems:
Slewing Rings
Single, double-row, or even triple-row with internal/external gear or no gear. Options in lightweight aluminum for compact platforms, or forged steel for heavy loads.
Slew Drives
Ready-to-install, IP-rated drive units. Available in high-torque or lightweight configurations, with low backlash and easy motor integration.
Rotary Actuators
A rotary actuator converts hydraulic pressure into controlled rotational motion for defense applications such as turrets, weapon systems, hatches, attachments, and stabilized platforms.
Lightweight or Heavy-Duty – Always Precise
Whether it’s a lightweight flanged slewing ring in an unmanned turret, or a planetary gear + slewing ring modulerotating a missile launcher — TGB products deliver precise, reliable movement with minimal maintenance.
Modular configurations and custom adaptations ensure the exact performance your platform needs — from low-profile UAV gimbals to heavy tracked weapon stations.
