True Zero Backlash Onvio reducers are designed with cantilevered needle bearing cam followers and rollers- not with pins and bushings found in other cycloidal designs. This allows for a controlled pre-load between the cam and cam followers, assuring zero backlash. This design permits the pre-load to be maintained throughout the L10 life of the bearings.
High Torsional Stiffness With every cam follower in contact at all times, the load is equally shared. This guarantees consistently high torsional rigidity independent of load position.
Accuracy All bearings are precision class bearings. The cam follower bolt circles are held concentric to 0.0002". This gives positional accuracies down to seconds of arc.
Low Compact Profile Onvio reducers offer a hollow bore input and low profile design. Coupled to a pancake motor, they can be installed in the smallest of spaces.

Onvio's authentic planetary, AP, provides designers with the greatest positioning accuracy and highest torsional stiffness, along with the lowest backlash gearbox available. The AP design incorporates single or two stages of planetary gearing to create five frames sizes with rated torque from 40 Nm up to 900 Nm. Standard backlash is 5 - 8 arc minutes and reduced backlash is 3 - 5 arc minutes, so designers can choose the appropriate level of precision for each application. Available in twelve standard ratios from 4:1 to 90:1 with optional ratios upon request. With a two-piece modular design, Onvio's AP gearbox can be customized to meet your OEM requirements.
Custom housing designs
Washdown environments
Integrated servo motor design
Various lengths of output shafts
Wide range of operating temperatures
Select Onvio's AP gearbox when low backlash and dynamic response are critical.

PG planetary gear units are divided into 21 basic groups depending on the different torques that are to be transmitted to the output shaft, which can vary from 0.05 to 65 kNm.
In fact, the product modular construction permits the coupling of bevel gears, worm gears, hydraulic brakes and a variety of input shafts to the planetary units, as well as providing for a wide choise of coupling flanges for hydraulic or electric motors.

The universal motor coupling is available by the means of a clutch fitting and input flange and bush adapters.
The series RG is made in 4 sizes (RG050 - RG070 - RG090 - RG120), one and two stages, reduction ratios 3/1 to 100/1 and nominal output torque 12Nm to 220Nm.
The planetary gearboxes Series RG give a remarkable precision (angular backlash lower or equal than 8 minutes of arc for one stage and lower or equal than 12 minutes of arc for two stages) and quietness (lower than 70 dB-A for the sizes RG050, 070 and 090, and lower than 75 dB-A for the size RG120).

Planetary gearboxes (PLG) have the highest continuous torque capacity of all types of gearbox; at the same time they have a very compact form, low weight, and excellent efficiency. Self-centering planet gears ensure a symmetrical force distribution. The ring gear also forms the housing of the gearbox. The gearbox output shaft is supported in two ball bearings so that it can withstand high axial and radial loads. The gearboxes are customized, e.g. for use in especially low ambient temperatures, or as high-power gearboxes with reinforced output shafts, or with special lubricants for very long service life.
