Swing gearboxes, also known as slewing gearboxes, are robust transmission systems built by TEBSA in Argentina for heavy-duty machinery needing strong, precise rotation. Since 1997, we’ve engineered these components to power equipment like excavators, cranes, and industrial machines across Argentina’s construction sites and farms. They allow the upper structure of these machines to pivot a full 360 degrees around a fixed base with reliability you can trust. Crafted with high-grade alloy steel and advanced forging techniques, TEBSA’s swing gearboxes deliver lasting performance at 50% less cost than original brands—backed by our 100% quality guarantee, perfect for tough jobs from Buenos Aires to the Pampas.

Technical Features and Advantages
TEBSA’s swing gearboxes, or slewing gearboxes, stand out as top-tier transmission solutions for heavy machinery in Argentina and beyond. With over 25 years of expertise since 1997, we’ve honed these components to meet the toughest demands of excavators, cranes, and industrial equipment. Here’s what makes our swing gearboxes a smart choice:
- Materiales de alta resistencia: Built with alloy steel or optional stainless steel, our gearboxes resist wear and corrosion—perfect for Argentina’s humid Pampas fields or dusty construction sites in Córdoba. Advanced forging and heat treatments like carburization ensure they last through years of hard use.
- Ingeniería de precisión: Featuring finely tuned gear ratios (e.g., 1:50 to 1:100 depending on model), these gearboxes deliver smooth, accurate 360-degree rotation. Whether you’re swinging an excavator arm in Buenos Aires or a crane boom in Mendoza, you get steady control every time.
- Heavy-Duty Torque: Designed to handle high torque loads—up to 10,000 Nm in some models—our swing gearboxes power large machinery without strain. This means reliable performance for digging trenches or lifting steel, even in rugged Patagonia conditions.
- Compact and Efficient Design: Their space-saving structure reduces weight (starting at 20 kg) while maximizing power transfer. This efficiency cuts fuel costs for Argentine farmers and builders, aligning with TEBSA’s 50% cost advantage over original brands.
- Opciones personalizables: Need a specific ratio or material? Our skilled team, responding within 24 hours, crafts swing gearboxes to your exact specs—whether for a 50 HP mini-excavator or a 200 HP crane. From prototype to production, we adapt to your drawings.
- Bajo mantenimiento: Sealed with durable tapered roller bearings and pre-lubricated with high-quality oil, these gearboxes need minimal upkeep. A quick oil check every 500 hours keeps them running smoothly, saving you time and repair costs.
