Drive Systems & Mechanics

Where Motion Meets Precision

When gears engage, transmissions lock into place, or a servo finds its path with absolute accuracy – that's when you see how much engineering goes into the smallest details. Drive systems and mechanical components form the functional heart of many model building projects: they transmit force, control movement, and bring realistic dynamics to life – whether in a 1:14 scale excavator, RC truck, or a high-precision custom model.

Drive Technology That Delivers – at GHW Modelbau

Our product range in Drive & Mechanics is tailored to all who don’t leave model engineering to chance. Whether you're a hobbyist or a professional working on a custom build – you’ll find components that keep their promise: dimensionally accurate, robust, and built to last.

With hands-on expertise and one of the deepest assortments in the German-speaking market, we’re here to support your project. Got questions about gear ratios? Need the right driveshaft for a 6x6 vehicle? Looking for differentials for a custom chassis?

We're happy to help – by phone Monday to Friday from 9:00 to 14:00 CET, or anytime by email at info@premacon.com.

⚙ Gears & Transmissions – Because the Right Ratio Matters

You want to control the lifting motion of a dump truck or design a slewing gear for an upper structure? One thing is key: the correct transmission ratio. We offer a wide selection of gears, including spur gears, bevel gears, worm drives, and internal gear rings in various modules, materials, and sizes.

At GHW Modelbau you’ll also find complete gearbox components and rack gears for linear motion – allowing you to transmit movement smoothly, powerfully, and with minimal backlash.

• Spur gears, bevel gears, worm drives & internal gear rings in different modules and materials
• Customizable transmission components – from servo drives to full chassis mechanics
• Rack gears for defined, linear motion

Whether it’s smooth startup, durable power transmission, or ultra-compact miniature drive systems – our components mesh perfectly.

🔗 Power Transmission – Controlled, Reliable, Strong

Planning a leadscrew for height adjustment? Need a quiet but powerful belt drive? Or a rugged chain system for a tilting mechanism?
Our power transmission components are built for efficient movement:

• Timing belts, chain drives, threaded spindles
• Matching connection parts for functional integration
• Scalable from servo mechanics to large mechanical assemblies

🧭 Bearings & Guides – For Precision Without Play

Designing a gearbox, mounting a swivel arm, or upgrading a suspension system? Bearings are essential wherever parts rotate. We carry a wide range, precisely tailored for model-scale applications:

• Ball bearings (radial & axial), plain bearings, rod ends, and specialty bearings
• Optimized for miniature diameters, high speeds, or combined loads
• All bearings are dimensionally accurate, low-friction, and pre-lubricated – ideal for tight installation spaces

🌀 Springs – For Controlled Return Motion

In model mechanics, movement often needs to return with precision or maintain tension under load. We offer a well-balanced range of:

• Compression springs
• Tension springs
• Torsion springs

All designed for technical model applications – from lever reset to suspension damping or preloaded mechanisms. Our springs perform reliably, even under continuous stress.

🔧 Servos & Accessories – When Every Movement Counts

Precise motion control is the heart of modern model technology – and servos are central to that. We offer not only high-quality servos but also a wide range of servo accessories, such as:

• Servo electronics
• Servo cables
• Servo testers

No matter the scale, load, or installation constraints, we have the right solution – from simple actuation to complex kinematics.
