Precision drives progress. Behind every smooth motion and every perfectly controlled system is a gearbox that performs flawlessly under pressure.

GearKo’s high precision planetary gearbox portfolio is built to meet that challenge—bringing together accuracy, durability, and smart design to power modern automation with confidence.

From high-rigidity systems to value-optimized designs, each series is engineered with a clear purpose: deliver dependable performance where it matters most.

 

TB/TBR Series — Quiet Precision, Solid Performance

The TB/TBR Series is where precision engineering meets refined operation. Designed with an integral structure, these gearboxes offer outstanding rigidity and stiffness, ensuring stable, repeatable motion even in demanding environments.

With backlash as low as 0–5 arcminutes, they deliver the accuracy required for high-performance applications, while maintaining impressively low noise levels. A self-sealing design helps prevent grease leakage, reducing maintenance concerns and supporting long-term reliability.

With a wide range of ratios available, the TB/TBR Series is a flexible solution—well aligned with industry standards set by leading global brands.

TD/TDR Series — Built to Carry the Load

When applications demand more strength, the TD/TDR Series rises to the challenge. Engineered for higher axial load capacity, this series maintains smooth, quiet operation without sacrificing precision.

Low backlash and a broad ratio selection make these gearboxes a strong fit for heavy-duty automation systems where both accuracy and durability are essential. It’s a dependable choice when performance under pressure is non-negotiable.

TE/TER Series — Strength Meets Smart Investment

The TE/TER Series strikes a thoughtful balance between rigidity and value. Built to deliver high stiffness and consistent performance, it also emphasizes long-term cost efficiency—making it a practical choice for businesses focused on total ownership value.

With its robust construction and versatile ratio options, this series offers reliable performance without overengineering the solution.

TCB/TCE Series — Practical Design, Proven Value

Not every application needs complexity. The TCB/TCE Series embraces a simplified, value-driven design that focuses on what truly matters: dependable performance at a competitive cost.

Targeted at the medium-end market, it maintains low backlash while streamlining the overall structure. The result is a gearbox that delivers solid, consistent output—ideal for applications where efficiency and affordability go hand in hand.

TF Series — Ready for Demanding Conditions

The TF Series is built for environments where loads are higher and expectations are tougher. With enhanced bearing support, it offers increased axial and radial load capacity, making it well-suited for more demanding operational conditions.

Despite its strength, it maintains low backlash, ensuring that precision remains uncompromised. It’s a robust solution designed to perform reliably under pressure.

TDP Series — A Step Forward in Design

Innovation takes center stage in the TDP Series. Featuring a one-piece gearbox-pinion design, it reduces runout while significantly increasing rigidity and overall system reliability.

This integrated approach simplifies assembly and enhances performance consistency, setting the TDP Series apart as a forward-thinking solution with no direct equivalent. It’s designed for applications where precision engineering truly makes a difference.

THA/THG Series — Precision That Lasts

For applications requiring long-term accuracy, the THA and THG Series deliver lasting performance. Specially heat-treated gears ensure durability while maintaining low backlash over time.

Available in frame sizes 047–110 and with optional motor integration, this series offers both flexibility and endurance—making it a reliable choice for systems that need to perform consistently over extended periods.

Engineered for Real-World Demands

GearKo’s planetary gearbox portfolio reflects a deep understanding of real-world industrial needs. Whether the priority is ultra-precise motion, heavy load handling, or cost-effective performance, each series is designed with clarity and purpose.

The result is not just a lineup of gearboxes, but a cohesive portfolio—one that helps manufacturers, engineers, and system integrators achieve reliable motion, efficient operation, and long-term value.
