In machine building, servo motors deliver speed and control—but a servo gearbox is often what makes a machine truly productive. A properly selected gearbox helps you convert motor speed into usable torque, stabilize motion tuning, improve precision, and extend the lifetime of the drivetrain. For OEMs and system integrators, gearbox choice is not an accessory decision—it is a core performance and reliability decision.
As a local distributor of GearKo and TGB, we support machine builders with selection, sizing, and integration advice so your servo system runs smoothly from commissioning to long-term production.
Why a Servo Gearbox Matters (Real Engineering Benefits)
1) Higher Output Torque Without Oversizing the Servo
A gearbox multiplies torque at the output shaft, allowing a smaller servo to handle heavier loads. This is critical for axes that see high load demand such as presses, screw drives, rotary indexing, and heavy handling.
2) Better Inertia Matching = Easier Tuning and Smoother Motion
One of the most common servo problems in machine design is high load inertia (large tables, long gantries, large pulleys, belts, or high-mass payloads). A gearbox reduces the reflected inertia seen by the motor, making control loops more stable and enabling higher acceleration with less vibration.
3) Improved Positioning Resolution and Repeatability
With reduction, the motor rotates more for a given output movement. That effectively increases output resolution and helps maintain repeatability—especially in indexing and start/stop applications.
4) Mechanical Protection and Longer Service Life
A quality gearbox improves torsional rigidity, helps manage shock loads, and protects mechanical components during rapid reversals and frequent cycles—typical in packaging, pick-and-place, and automated assembly machines.
GearKo: Precision Planetary Gearboxes for Servo Axes
GearKo focuses on precision planetary gearboxes built for demanding automation. In the GearKo product positioning and datasheets, the themes are consistent: very low backlash, standardized interfaces for fast installation, and service life designed for continuous operation.
Key GearKo Highlights (from the manufacturer)
-
Low backlash: GearKo states gearboxes “have as little as less than 1 arc minute of backlash.”
-
Standardized flange interface: The TB/TBR series datasheet notes a standardized flange interface for convenient and fast installation.
-
Service life for continuous operation: The TB/TBR datasheet states that for continuous operation, service life is no less than 10,000 hours (per stated conditions).
Where GearKo Planetary Gearboxes Fit Best
-
Laser & CNC axes: X/Y/Z axes, feeders, high-speed contouring systems (inertia matching + stiffness)
-
Packaging machines: feed, cut, seal, indexing, and synchronized axes
-
Robotics & gantries: pick-and-place, belt-driven axes, rotary joints requiring low backlash
-
General OEM automation: anywhere you need compact torque density and reliable repeatability
TGB: Slew Drives for Heavy Rotary Loads and Harsh Environments
TGB’s slew drives are designed for robust rotary motion, with product pages emphasizing low backlash, globoid design, and enclosure protection—ideal for applications where the rotary axis must hold load and operate reliably in demanding environments.
Key TGB Highlights (from the manufacturer)
-
Low backlash + globoid design: TGB describes the BE Standard Series as a high-precision slewing drive offering low backlash and a globoid worm gear design for industrial applications.
-
IP65 protection: TGB states the BE Standard Series has a fully enclosed housing with IP65 protection.
-
Dust/water protection sealing: The BE series page describes external sealing for protection against dust and water.
Where TGB Slew Drives Fit Best
-
Heavy rotary tables / large turntables: high load holding and robust rotation
-
Industrial handling and positioning systems: rotating clamps, orienting mechanisms, large fixtures
-
Outdoor or harsh environments: equipment exposed to dust, water splash, or tough site conditions
-
Automation requiring compact rotary reduction: when you need a strong, integrated rotary reducer concept
