For high-precision automation equipment, what range should the return clearance (backlash) be controlled in when selecting the FAD series planetary reducer?

The selection of return clearance (also known as backlash) for FAD series planetary reducers is crucial for high-precision automation equipment.

For high-precision applications, the return clearance of FAD series planetary reducers should be controlled within 3 arc minutes.

1、 Suggestions for high-precision selection

The FAD series planetary gearbox meets the needs of different applications through different precision levels. According to its product model description, the backlash level is mainly divided into:

P0 level: Ultra precision backlash

P1 level: Precision backlash

P2 level: standard backlash

2、 Accuracy level and application scenario reference

The industry standard roughly divides the backlash accuracy of planetary gearboxes into the following levels, which helps you make more accurate selections:

3、 In summary:

To ensure the positioning accuracy and operational stability of high-precision automation equipment, when choosing FAD series reducers, you should clearly specify the required backlash accuracy of ≤ 3 arc minutes and select products with P0 or P1 accuracy levels accordingly. For example, in scenarios such as industrial robot joints and precision CNC machine tools that have strict requirements for repetitive positioning accuracy, the backlash value even needs to be controlled within 1 arc minute.
