Our high-precision cycloidal gears provide excellent performance and long service life. Our service team ensures fast delivery, short response times, and professional commissioning to integrate your systems smoothly and efficiently.
RD2 Series – Precision Nabtesco Gearbox
- Backlash less than 1 arc/min
- Complete gearhead version ready to mount (lubrication included)
- Easy-to-install motor mounts
- Highly compact with high torsional rigidity
- Integrated angular bearings for increased load capacity
- Wide gear ratio availability (up to 258:1) without increasing gearbox size
- Torque capacity up to 5 times nominal torque (E-Stop)
RS Series – Precision Nabtesco Gearbox
RS gears are specifically designed for reliable and precise positioning of heavy loads up to 9 tons. The cast iron base ensures stable and durable floor mounting. Their high performance and precision make them superior to conventional helical gears.
GH Series – Precision Nabtesco Gearbox
Gear reducers (based on RV gear sets) designed for high output speeds, making them ideal for robot axis automation, machine tools, and conveyor systems.
Advantages of Nabtesco Gearboxes
Nabtesco’s Cycloidal Gear technology is the far superior choice when compared to traditional planetary and cam indexing devices.
The Nabtesco Reducer consists of a patented two-stage cycloidal design that provides large torque, high-ratio and significant shock-load capabilities with extreme precision and excellent quality. The RV gear utilizes rolling contact elements to reduce wear, extend life and lower backlash with the unique pin and gear structure of the cycloidal design providing higher shock resistance than traditional reducers and further reducing backlash.
The reducer also incorporates a set of large, internal angular support bearings that provide large moment capacities and negate the need for external support devices
Other advantages
- Best load capacity in the market
- Compact size to optimize machine space
- Unmatched movement accuracy
- Highly compact with high torsional rigidity
- Integrated angular bearings for greater load capacity
- Wide gear ratio availability (up to 258:1) without increasing gearbox size
- Torque capacity up to 5 times nominal torque (E-Stop)
Nabtesco’s Patented 2-stage Cycloidal Gearbox
A. Integrated Angular Ball Bearings
- Allow for support of external loads
- Increase Rigidity and allowable moment
B. 2 Stage Reduction Mechanism
- Reduces vibration: Slower rotational speed of the RV gears
- Reduces inertia: Reduced size of input coupling (input gear)
C. Dual-Sided Crankshaft Support
- High torsional stiffness, lower vibration & high schock load capability
D. Rolling Contact Elements
- Excellent Starting Efficiency
- Low wear and longer life
E. Continuous Gear Teeth Contact
- Very low backlash (less than 1 arc-min)
- Higher shock load capability (5x rated torque)

Frequently asked questions about Nabtesco Gearbox
What is the difference between Cycloidal Gearbox and Traditional gear mechanism?
Loads
- Planetary Gears may run at higher speeds.
- Cycloidal Gears are very good for extremely heavy loads.
Ratios
- Planetary Gears will work with very low Ratio’s.
- Cycloidal Gears work at higher ratios allowing them to be driven with less power.
Accuracy
- Planetary Gears are good if positioning accuracy and lost motion are not a concern.
- Cycloidal Gears are best in applications for high positioning accuracy and a minimum lost motion is required.
Maintenance
- Planetary Gears are ok if regular “monthly maintenance” is acceptable for the application.
- Cycloidal Gears are best if little maintenance and long gear life are required.
How do I choose the right Nabtesco Cycloidal Gearbox for my application?
Things to consider when choosing a Gearbox. After many years developing Cycloidal Gears our engineers have created some basic questions to help you in the beginning steps of selecting a gearbox for your application.
- What environmental conditions will the gear box need to endure? (Operating temperature, dust, moisture exposure, etc.)
- What physical size envelope does your gear box need? (any shape or space requirements)
- Maintenance and lubrication access? (After the application is assembled how will you maintain the gear box?)
- How much torque do you require to do the work required by the application? (Weight it needs to move.)
- What, if any, speed requirement does the application require? (How fast you need the gear box to go.)
- Angle of the gearbox mounting? (Horizontally ,vertically or angled.)
- Moment rigidity? (Weight deflection of the gear box shaft due to the fixture and work load.)
- Torsional rigidity? (Shaft deflection, stopping and starting the application load.)
