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 flexible bearing is used in harmonic drive systems to transmit torque from the input shaft to the flexspline while accommodating controlled elastic deformation. It creates the elliptical wave motion needed for gear reduction.
Common materials include high-carbon chromium bearing steel (e.g., SUJ2, 52100), stainless steel for corrosion resistance, and ceramic for high-speed applications. The specific material should be confirmed for the intended application.
Typical ranges include bore diameter 10–100 mm, outer diameter 30–150 mm, width 8–25 mm, dynamic load rating 5–50 kN, static load rating 10–100 kN, radial clearance 0.005–0.020 mm, tolerance class P5–P4, maximum speed 3000–10000 rpm, operating temperature -40–120 °C, vibration level V1–V3, and weight 0.05–2.5 kg. These are reference ranges and must be verified for the specific model.
You should consult the legal manufacturer or supplier to confirm model-specific values such as dimensions, load ratings, clearances, and standards compliance. Always verify that the bearing meets the requirements of your harmonic drive system.
