Buying Notes

Specification check: confirm OD, ID, SOD, FH, EH, voice-coil group, and material code instead of ordering by model alone.

Sample matching: send clear photos, drawings, or key measurements when the original model is unclear.

Quote support: share quantity, destination market, and sampling needs so pricing and lead time can be confirmed.
