Onvio Speed Reducers Choose from Three Reducer Product Families AP Highest Performance In applications that demand the greatest positioning accuracy, highest torsional stiffness, and lowest backlash, Onvio's authentic planetary, AP, with its compact axial design, is the correct choice. • Precision, hardened, ground gears insure backlash down to 3 arc minutes • High torsional stiffness • Single and two stage construction for a wide range of standard ratios • Short, compact design HP Greatest Flexibility For applications requiring low inertia and low backlash for speed control and precise positioning,...

AP Speed Reducers Highest Performance 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. Select Onvio's AP gearbox when low backlash and dynamic response are critical. 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. Modular...

High Capacity Output Bearings Two output bearings, located forward in the gearbox result in higher bearing capacity and longer bearing life Low Backlash Hardened, ground gears guarantee low backlash - down to 3 arc minutes Universal Servo Interface Flexible slotted bolt circle and oversized pilot allow for easy motor installation and no adapters Floating pilot and high capacity input bearings guarantee alignment between motor and gearbox Cool Operation Unique fins dissipate heat from servo motor and help to lighten gearbox ONVIO • Servo Speed Reducers 4
