A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The reduction ratio can range from 3 to 100, with single-stage units typically offering 3–10 and multi-stage units up to 100. The exact ratio depends on the number of teeth on the sun, planet, and ring gears.
Gears are often made from case-hardened alloy steel such as 20CrMnTi, while bearings may use bearing steel like GCr15. These materials provide durability and wear resistance.
Backlash is typically up to 0.1 degrees, which is suitable for precision positioning. Lower backlash may be available for applications requiring higher accuracy.
You must confirm model-specific parameters such as rated output torque, reduction ratio, efficiency, input speed, operating temperature, protection class, and housing material with the legal manufacturer or supplier. These values are reference ranges and may vary by model.
