SHF / SHG output-bearing selection depends on the full reducer designation and flange arrangement. Use the existing dimension table to identify a candidate, then check the output interface and load case. These references describe output support, not the wave-generator flexible bearing.
SHF / SHG output-bearing selection depends on the full reducer designation and flange arrangement. Use the existing dimension table to identify a candidate, then check the output interface and load case. These references describe output support, not the wave-generator flexible bearing.
CSG / CSF references use another reducer-family interface. Keep the drawing and rated conditions together when comparing alternatives. Compare the related series.
Individual model pages are being added. Use the series table or send the complete model number and drawing for review.
Read all dimensions against the matching drawing. Blank values mean unspecified, not zero. Reference numbers do not establish full interchangeability.

The existing published LYDL table covers sizes 14–50. Other sizes, including 65, require a separate drawing and availability confirmation.
Technical reference: Harmonic Drive official gear-unit information. Brand names identify reference families only. Supplied LYDL dimensions, tolerances, load ratings and acceptance requirements are defined by the drawing and quotation agreed for the order.
