Import Tips

Specify inner/outer diameter tolerances (±0.001mm typical) in technical specs to validate precision ceramic classification

For mixed alumina-zirconia, provide composition breakdown; pure zirconia preferred for highest durability

Watch for reclassification if sleeves exceed size limits or lack fiber alignment channel opening
