IKO Super Thin Linear Roller Bearing SR25 from China
IKO SR25 super thin linear bearing uses needle rollers caged between raceways for space-constrained applications like semiconductor probe cards. While primarily roller-type, certain ball variants fall under HTS 8482.10.5012 as linear bearings.

Import Tips
• Confirm roller vs ball configuration via cross-sectional drawings for correct 8482.10 vs 8482.40 classification
• Document allowable moment loads (Mc, ML, MP) as they determine linear bearing designation
• Cleanroom packaging specifications required for semiconductor import documentation
